Meet Artist and Industrial Designer Brooke M Davis

We’ve been following Brooke M Davis’ work since 2012 after she purchased her full size ShopBot. Brooke has continued to design and fabricate beautiful, organic, functional furniture that can easily be categorized as art. In fact, Brooke’s work can be found at the CraftTexas 2018 show at the Houston Center for Contemporary Craft, September 29, 2018 — January 6, 2019.


“Pilo Side Table” • Wood Side Tables 2019 • Walnut, Swarovski Crystal, Steel

Brooke’s newest work includes the plush tufted walnut side table (above) that is both elegant and inviting. Not only will it be displayed in the Texas Furniture Makers Fair at Kerr Arts Cultural Center in November, she will be showing it in Milan at the Salone Del Mobile in April 2019.

Keep an eye on her website: for more exciting work to come.

MakeShift, her design consulting service and production facility, continues to thrive and regularly sees a wide variety of work through the shop that keeps things interesting. Brooke and her team handle prototyping work, product development classes, design consultation, and more to the Austin, TX area—and beyond. This is a unique space where real product ideas come to life.

We are looking forward to seeing what’s next for Brooke.


Take a look back at the story about Brooke from 2012 below.

Brooke M Davis Design blurs the line between artisan and designer by combining artistic expression with design precision to produce luxury craftsmanship. The process involves coupling mass production techniques like computer aided design with hands on master craftsmanship to create new and exciting results. With individuality in mind, this process allows for ease of customization at the client’s request.

Brooke’s process of discovery and creation for Tablescape No. 1 is much like it is for all her original works. “It’s a fluid process, and it always involves my ShopBot CNC,” notes Brooke. “I always have in mind that CNC is going to be integrated into my process. I’ll often start by making a 2D pencil sketch, then build on the idea by doing quick modeling in wet clay, to see where this takes me. I’ll photograph the models, and bring them into computer and use CAD to hone and clean up the lines … It’s a fluid process. I’ll then go back to clay to continue to play with the work. Sometimes I’ll draw on top of the photographs and bring that into the computer to further develop the design.”

Brooke’s collections range from high-end one-of-a-kind pieces to limited run productions. With quality craftsmanship and attention to detail, every piece is made to order with quality in mind. She works with individual clients, interior designers, and architects to offer a variety of services to meet innovative project needs. Specialties include limited run CNC production, industrial design, furniture design, and custom architectural installations.

“I’d worked with ShopBots throughout my education and teaching positions, so I was very familiar with their tools and capabilities. CNC technology became ingrained into my creative processes from the start, and I always integrate it into my design and production process. I finally bought my own ShopBot in May of 2011 and it’s been everything I knew it would be.

One of the things I really like about ShopBot is the community that surrounds it. The people at ShopBot are great — very helpful if I ever have a question. And there’s a very supportive and active group of users on the forum, so you feel like you’re part of a larger group that’s very much into CNC and helping one another succeed.”

Brooke also founded the community hacker space, make+SHift in 2011. ” It’s the only Design on Demand Shop for product developers in Texas!” says Brooke. “We provide you with the necessary design resources to make your ideas a reality. We offer design consulting services, CNC prototyping, and classes to advance professional development, plus comfortable work-space all in one place.”

Brooke notes, “One of the things that’s been wonderful about opening make+SHift is that I learn something new all the time from my customers. They bring new projects and challenges to the table, and my team gets to think of new ways of solving problems. It energizes my own design thinking as well.” 

ShopBot in the Theatre: USITT Master Class – Southeast Section 

The scene shop at Coastal Carolina University in Conway, South Carolina, has been making good use of their 4’x8’ ShopBot PRSstandard for creating various props for stage productions, including plywood forests of trees. Recently, the theatre department asked ShopBot to conduct a series of Master Classes for the Southeast Section of USITT (United States Institute for Theatre Technology) to learn more about, and share the capabilities of, their CNC machine with other theatre programs throughout the southeast.

One topic that seemed to spark everyone’s interest was 3D carving. With that in mind, the first demonstration was how to import a 3D file, in .stl format, into the VCarve Pro software, which is shipped with each ShopBot tool. Placing the “component” into the software in the correct orientation is a simple process. The model we chose to make was thicker than the 1.5” pink insulation foam that we had available, so we foreshortened the Z-height in the model to create a “bas” or low relief that would not be evident when looked at straight on. Another option to create the effect would be to use the slicing feature available in VCarve to create a series of carvings (slices) that could be stacked up after machining. Since we went for speed rather than detail, we used the same .25” ball nose bit to do a roughing pass over the entire model, and a finishing toolpath over the right side of the model.   

The bas relief of the imported Dia de los Muertos skull was subjected to two different tool paths. The entire model inside the larger rectangle was given a roughing pass to clear away the excess material. For the finishing pass, a smaller rectangle was selected. The stepover and feed/rate were changed to enhance the final result.


Another option is to use the slicing option available in VCarve Pro/Aspire to slice the model into sections that are the thickness of the available material, and stack them up after 3D carving.

Even experienced ShopBot operators learned something new when going over the basics of ShopBot set-up and the tools within VCarve Pro. Want to join all the open segments in an imported .dxf file or change all the individual segments into a sweeping curve? Want to trace a bitmap? Want to recalculate all the toolpaths in one go? Want to get an estimate of the time to machine a part? There’s a tool for that.

While the skull was being 3D carved, we split up and worked with smaller groups on different projects on different machines. On the big ShopBot gantry tool that belongs to Coastal Carolina University, we worked on a shop stool project that is available on the ShopBot website.

Screen shot of shop stools laid out so that the slot size can be adjusted for the actual thickness of the material.


Finished shop stools.

On the other Desktop, we worked with a V-bit. Richard demonstrated how to import a bitmap, trace it, and VCarve the result.  The CC was an example of how to use the VCarve toolpath tool to create a raised design by selecting the design, and a border. The CC is reversed so that the carving can be used as a stamp for textile design.

By painting the board first, then carving into it, one can easily create a two-color sign or design. (Or perhaps you have a piece of scrap material, and the board was already painted and placed back in the material pile.)

Session 2 of the Master Class included some additional options. VCarve Pro is 2D CAD and 2D/3D CAM software, so you can import 3D files and toolpath them, but you cannot design them or manipulate one that you have imported. Aspire is the big sister of VCarve Pro, and is a 2D/3D CAD and CAM software. In other words, you can “puff up” 2D vectors into 3D models. Another of one of the tools in Aspire allows you to import a black and white image and create a 3D component based on the grayscale of the photo. As an example, we snapped a photo of a fish on the wall at our restaurant, and used Aspire to create a 3D carving.

With the small size of the second session, attendees could get some in-depth instruction on options or ideas that they were interested in. Two-sided machining, setting up jigs for multiple copies, and the rotary indexer for machining in the round were but a few of the topics that had heads spinning and ideas flowing as folks headed back to their own shops.

48 contestants. 48 hours. One winning idea.

Make48 Film Crew at Work

As a product design student walking into an event where teams are tasked with designing a product, I didn’t quite know what to expect. Every day at school we brainstorm ideas, sketch them out, prototype them over and over, and then at the end of the project, market and present a finished prototype to our peers. As I looked around the empty shop in the quiet hours before the competition began, I wondered how closely what I was about to witness would resemble the process of product development that I had grown so familiar with. I was in Towson, Maryland at the Stanley Black & Decker Makerspace for Season 3 of the TV show “Make48” in which 48 contestants have 48 hours to develop a product, produce a working prototype, create a short promotional video for that product, present it to a panel of judges, and do it all within the given challenge category and specific budget constraints. Sounds easy enough, right? This year, the contestants were all college students from universities all over the country—but I wasn’t there as a contestant. I was invited as a tool tech for ShopBot Tools, there to help the teams realize their ideas through physical prototypes and to guide them through the process of 3D modeling and 2D vector design for CNC machining.

Once the contestants began to arrive and I had a chance to talk with them a little, it became apparent that the competition drew a heavily engineering-based crowd. Of course, there were outliers who didn’t fit into this category, and there was one team that didn’t have a single engineering or design-based member. Those were the teams I was most interested in following. Sometimes throwing people out of their element and having them do things they wouldn’t normally do can yield surprising and positive results.

Right before noon on Friday, we all gathered around the huge stop clock at the front of the room, eagerly waiting for the 48 hours of chaos to begin. The giant steam whistle blew loudly, like the start of a factory workday in days gone by. It’s then time for the teams to get down to business and time for the tool techs to stand at the ready once the prototyping begins. Straight out of the gate, each team tackled the brainstorming phase in different ways. Within the first two hours, one team had created a model and 3D printed a rough prototype while many other teams struggled to narrow down the category of products that they wanted to focus on. Some teams immediately turned to sketching out their thoughts, while others pulled their ideas together into ordered lists, and one team had a mess of notes scattered across the table with no rhyme nor reason. Unfortunately for me as a tool tech, I was merely a spectator in these first few hours as teams decided what they wanted to create. It wasn’t until they began thinking about prototyping that my expertise came into play. One-by-one, the teams began to send their members out to the tool techs to begin fabricating their ideas.

Cutting prototypes for the TV camera.

For me, that was when the most rewarding part of the whole weekend began; the first contestant came to us with their idea, and we helped them translate their idea into a real, tangible product. We worked with them to create or edit their CAD files and guide them through the process of converting those vectors into a ready-to-cut .sbp file. As the machine warmed up and we zeroed the axis to the new material, I watched the whole team gather around the tool. As the spindle began to cut away at the material, there was a visible change in their expressions as the magic of technology brought their vision into reality. Watching their faces light up with pride as they watched the ShopBot cutting out their product or their logo was rewarding.

If there’s one thing I’ve learned about design in my time at school, it’s that presentations matter. There were many rapid prototyping techniques available at this event to bring these teams’ projects to life. In addition to the two ShopBot CNC machines, there were twelve Ultimaker 3D printers, an Epilog laser cutter, a large vinyl cutter, a Bridgeport mill, and a CNC plasma cutter, as well as a well-stocked wood and metal shop filled with many Stanley Black & Decker power and hand tools. Although several universities represented have ShopBot tools in their programs, the teams unfamiliar with CNC technology found some machines intimidating. Once we cut out a few things on the ShopBot ourselves, you could see the curiosity and confidence in the faces of the contestants begin to grow as teams got excited about the potential of prototyping on CNC. On the last day, as I looked out on the stage as each team presented their products to the panel of judges, I admired all the work we’d done with the ShopBot. Without our ShopBot Desktop and large PRSalpha 5’x10’ gantry – or any of the other digital manufacturing machines – the outcome of this competition would have been very different, and certainly would have taken longer than 48 hours. In the world of design, an idea is nothing if you can’t see it through to a working product.

I really wish that I could tell you more about all the incredible products that the teams produced, but I’m not allowed to share that information until the show is released next year, so you’ll have to wait until then.

Timeless design and old-fashioned customer service lead to Durham Bookcases’ success

We recently popped in for a quick visit with Phillip Fletcher to see how his business, Durham Bookcases & More, is doing and to take a peek at his 17-year-old ShopBot. Rest assured, his business and his ShopBot are looking good and continue to be ready to take on customer needs today and into tomorrow.

Fletcher’s shop sits just beside the railroad tracks in Downtown Durham. He’s been working in this space since the early 70’s when Durham was a tobacco town and Main Street was still a gravel road. The area has changed a lot since then. He now finds himself surrounded by pricey new condos and busy boutique restaurants – brimming with college students and professionals alike.

For more than 30 years, Phillip and the crew at Durham Bookcases & More have continued to produce and sell quality bookcases, as well as other real wood furniture items, that fit in both contemporary and traditional homes. Foot traffic is still an important part of the business and allows the Durham Bookcases staff to really connect with customers. However, internet presence via their website and through online retailer, Etsy, have enabled them to expand their sales footprint – selling all over the world. As many businesses and manufacturers have similarly been affected – especially since 2008 – Durham Bookcases has navigated shifts in material pricing and availability due to economic conditions that are still present today. However, they remain committed to reasonably priced furniture that customers can feel good about investing in, furniture that stands the test of time.

The ShopBot that Phillip purchased in 2001 continues to be an integral part of his manufacturing process. Over the years, he has amassed thousands of files – standard and custom jobs – that he runs on a ticketing system. Staff are able to systematically move projects through the shop using a combination of traditional shop tools and the ShopBot; and are able to scale up to accommodate demand.

Durham Bookcases believes in making quality products that last, just like ShopBot does.

Take a look back at the original story we ran on Phillip in 2011 below.
Written & Published by: Michael Berliner

Business: Durham Bookcases (& Other Cool Wood Stuff)
Where: Durham, North Carolina
ShopBot Tool:
 96 X 48 PRSalpha (purchased in 2001)

Furniture maker Philip Fletcher founded Durham Bookcases back in 1995. “Our goal from the beginning was to build bookcases at competitive prices with high quality workmanship.” As time has passed, Durham Bookcases has grown their offerings to include custom-built entertainment centers, wall units, office furniture and bedroom furniture, and increased the variety of woods, sizes, & options to continue to please their customers.

Fletcher says his guiding philosophy has always remained the same. “I’m a custom maker. It always works best if my customers meet with me one on one, to discuss their needs fully. That way, the customer is pleased with the outcome. I know my furniture is going to last — so I want the customer to be happy with their purchase for a long, long time!”

It was about 10 years ago that Fletcher added digital fabrication technology to the core of his manufacturing process. He contacted Durham neighbor ShopBot Tools and has been pleased with the tool, and his relationship with ShopBot, ever since.

“My ShopBot is a workhorse,” says Fletcher. “Quite simply, it’s reliable.” Over the years Fletcher has found that the ShopBot’s easy interface is a boon because it’s easy to train employees how to use the software. Asked how long it takes to bring a new employee up to speed, Fletcher didn’t hesitate to answer: “Twenty-four hours.”

When it comes to technical problems, Fletcher smiles and says, “It usually turns out to be a user issue, not a problem with the tool. Customer service has always been friendly and available when we need it.”

Durham Bookcases has been in business long enough to have experienced busy times and quieter times, and has witnessed shifts in customer attitudes and interests. “There was a trend in recent years for customers to want only ‘green’ materials,” notes Fletcher. “I like to point out that by using quality woods is the best way to be green — because furniture that lasts for 25 years and more doesn’t ever need to be recycled!”

Why We Build Our Tools Ourselves

You may know that ShopBot Tools sells CNC tools, serving small-to-medium sized manufacturing companies. What you may not know is that we build our digital fabrication tools ourselves – using digital fabrication. We design and build our own tools, the electronic controls for the tools, as well as the software that runs the tools, which differentiates ShopBot from most other companies selling affordable CNC equipment.

As a potential CNC owner, the fact that we design and build our own tools makes a meaningful difference to you. With a ShopBot, you get a tool from the people who designed and manufactured the tools and the software that runs it. You get your help and support from the people who know and understand the equipment and its control. The equipment, the design, the wide range of training and support resources that we make available to you – all are based on our own continual involvement in small manufacturing using the digital technologies of the equipment itself.

We use the tools ourselves all day, every day. That’s why we understand how CNC, digital fabrication, and robotics are used in production. We make use of that knowledge in the development of our products and in the technical support we provide to you for your production success.

Our involvement in design and manufacture, combined with our full engagement in customer support, creates a cycle of product enhancement that we think of as our “Turbine of Innovation.” Here’s how it works:

There is a continuous loop of integrated feedback between our manufacturing and our customers’ manufacturing. We learn from our production. We learn from your production, and we learn from you. We integrate this learning and discovery into our design, development, and improvement process. This process efficiently drives the innovation that provides you with greater productivity, product reliability, and ease of use.

An advantage of building our own tools rather than importing and reselling others’ equipment is that we’re able to rapidly make iterative improvements and enhancements to tools and software. We continuously integrate these improvements into our products and keep ShopBot owners in an upgrade loop. When we develop something new, it does not obsolete your previous investment; instead we focus on upgrade paths to keep your tool in that Turbine of Innovation loop. Even 18-year-old ShopBots have been updated to have many of the capabilities of new tools – they keep working year-after-year. Because of this longevity, ShopBots keep their value and usefulness rather than becoming a financial and logistical burden to your shop.

We are currently in the process of rolling out our next generation controller for digital tools and equipment. Representing several years work, it’s both hardware and software that improves motion, making fabrication faster, smoother, and easier. It allows monitoring and tuning of tool performance and tracking usage and job flow. We call it FabMo (digital Fabrication and Motion platform). FabMo will first be available on our small tools this summer, then we will begin shipping on full size tools, and, shortly after, will be available as an enhanced, drop-in-controller for older ShopBots – giving them new features and capabilities.

And yes, we get a kick out of developing and building the tools ourselves. We like hands-on. We like production. We enjoy using technology to stay competitive – and we enjoy producing the kind of product that will empower your competitiveness and appreciate the opportunity to help you succeed.


Digital fabrication technology is the key to making small manufacturing competitive again

Over 20 years ago, we had an idea to bring digital control to production tools, but at a human scale —digital fab technology at the time was only available for large industrial applications. We wanted to make the technology accessible to entrepreneurial individuals, small shops, and small-run manufacturing. 

History shows that our idea caught on. The press now calls this concept of digital technology being used competitively by small manufacturing: “The next industrial revolution.” Checkout how digital fab works for our own manufacturing:  “Eating Our Own Dogfood … ”.

Returning small manufacturing to our communities can restore their vitality. Manufacturing is the single most effective economic activity for producing value. It preserves our quality of life; it keeps us creative; and it keeps us competitive. Small manufacturing is especially effective because of its close relationship to the local economy, its proven role in education and workforce training, and its integration within a community.


We believe in small manufacturing and we practice it.

We use digitally controlled equipment (often our own ShopBots) to produce ShopBot tools. We utilize the continuum of digital fabrication technologies – from the digital model of our tools, to digital prototyping, to full CNC production of almost everything we make. As well, we use digital technologies in our marketing, logistics, and other business activities. We believe that it is these technologies that will make small manufacturing realistically competitive again, right here in the US.

In short, we are small manufacturers of digital fabrication equipment and we use digital fabrication to produce that equipment. We live the idea. We help it work for you!

Popular Pastime Reintroduced by ShopBot Tools at the Maker Faire Bay Area

The 13th Annual Maker Faire Bay Area, which took place May 18th-20th, once again did not disappoint. The weather was beautiful and there was an estimated attendance of 90,000! Packed with hands-on and how-to sessions, makers young and old were inspired and excited. New programming was added this year: Thursday After Dark at the Exploratorium; Industry, Career, & College Day on Friday (See: The World Needs more Makers article on; and there was the addition of the Learning Lab in Fiesta Hall.

The ShopBot booth was converted into a pop-up factory; creating a start-to-finish production line using the ShopBot Desktop MAX, Handibot® Large Sheet Tool and Handibot Smart Power Tool – Adventure Edition tools to make yo-yos. Yes, yo-yos!! We painted and pre-cut baltic birch 1/2” plywood into sheets to fit on the Desktop MAX. Then, we handled the cutting, drilling, and carving as a batch process for the insides of the yo-yo pieces. Engraving and edge round overs on the painted side of the yo-yo pieces (the fronts) were then processed on one of the two Handibots. After the machining operations were complete, we lightly sanded the pieces, then completed assembly using a dowel pin and string to then pop the sides together and…voila! Using our booth as a live production and assembly shop was a demonstration of how many products can be designed, then manufactured, using CNC (digital fabrication) in a systematic, consistent, and highly efficient manner.

Close to 1,000 yo-yo’s were distributed to attendees at Maker Faire over the 3 day event!

We were thrilled with the abundance of social media posts generated at Maker Faire. Posts were shared by makers with the yo-yos created at the show and pics of themselves with our giant 44” foam yo-yo (cut on a 4×8 PRSalpha tool and assembled pre-show) with the hopes of being selected as the drawing winner for the Handibot Smart Power Tool giveaway. We selected at random from all the social media posts shared publicly and tagged with #goShopBot, #goHandibot, @ShopBotTools, and @HandibotTool. And the winner is… Heather Taylor Price! Heather is a maker and works at a library makerspace at a high school in Utah – she has been considering adding CNC to the makerspace for quite some time and now has the opportunity to do so. We can’t wait to see what she comes up with for the students to tackle! You can follow Heather on Twitter: @skyridgelibrary and @heathertaylorprice.

Midday Saturday, our very own Bill Young participated in a panel discussion at the MAKE: LIVE stage. Experts in digital fabrication including Josef Prusa (Prusa Research s.r.o.), Dan Shapiro (Glowforge), and Bill Young (ShopBot), moderated by Matt Stultz, discussed the current state of digital fabrication and where they see it moving forward.

One of our big highlights was Saturday afternoon, at the MAKE Center Stage. Ted Hall presented: “How Digital Fabrication Promises to Make Small, Fulfilling, Local Manufacturing Competitive Again.” Ted talked about an invention his uncle had designed 30+ years ago and how, until very recently, there wasn’t an affordable way to produce this or many other inventions without excessive upfront costs and huge production numbers. Today, however, with the availability of enabling tools in the digital fabrication realm (CNC, 3D printers, laser cutters, etc.), Ted’s uncle and makers all over the world can be competitive.

Ted’s presentation was based on a series of Medium articles that he’s been writing. Learn more about these themes: leapfroging current mass-production and replacing it with methods that can make the small producer competitive again, Digital Fab Renews Small Mfg, Complexity Comes Free, Leveraging Agility & Entrepreneurial Energy.

The next opportunity to hear Ted Hall, ShopBot’s Founder & CEO, speak will be at the CNC Symposium at IWF, August 21st.

Maker Faires are popping up all over the world. While we can’t be at all of them, we encourage ShopBotters to take their Handibot, Desktop, or Desktop MAX to a Maker Faire nearby so you can show off what you design and make. You get to watch kids of all ages light up, they learn about how to make a classic toy (like what we did) or another object, and it provides an opportunity to get to know other makers in your area.

Taking my business in a new direction

Well the last four years have been challenging to say the least. To get caught up as quickly as possible, in early 2014 we moved into a 6,000 sq ft space and purchased a large CNC machine to grow our custom closet business. In short, business has continued to increase and we have a growing base of happy customers for both our retail closet installations and our wholesale closet parts.

Designing, manufacturing and installing custom closet systems like this one has been the main focus of our business for the past several years

However I have not found it easy to keep up. We immediately ran into problems with the fancy new CNC machine, along with almost everything else that I purchased. And unfortunately while I have been lucky enough to have a couple of good long-term employees, I have not been able to build a capable team to help us scale or even to keep up with the daily workload effectively. Along the way I’ve learned a lot about working with people and running a business that I wish I had known 30 years ago when I was just getting started. I’ve also learned a lot about myself, what I’m good at and not so good at, and what I like to do and don’t like to do.

Wholesale customers, including contractors and other closet companies, have become a sizable part of our revenue

And so I’ve come up with a plan. I’ve decided to close my shop and team up with two other local businesses to serve both our residential and wholesale customers. One is a former competitor who is handling all our retail leads (in exchange for a small percentage of whatever they sell). The other local company, with whom we will be partnering on the wholesale closet business, is another manufacturer who has a very substantial production facility but has been lacking a coherent order entry system or any way to price out a lot of small jobs efficiently.  The online catalog/order entry/customer management system that I’ve been building fits the bill perfectly.  Combining our customer base and ordering system with their production capacity will enable us to grow together – and the best part is that I can work from home, without the headaches or overhead of maintaining my own production facility.

I’m excited to be making this huge transition, but a little nervous about the next step, which is to sell all our equipment and get the space cleared out. After some consideration I’ve decided to use an online auction service to liquidate everything at once. Here is the sale info (bidding ends July 20 2018). Highlights include our big throughfeed router, two edgebanders (one for curves!), forklift, scissor lift, and plenty of router bits, hand power tools, storage cabinets and displays, office furniture and cabinetry, and much more!  And yes, I am selling my ShopBot.  It’s a pretty big deal after owning a CNC machine (or two) for almost 19 years.

Several dozen pieces, parts and projects of various nature, all custom designed and cut with a ShopBot CNC machine

Family reunion: a few examples of the hundreds of projects completed on my ShopBot over the last two decades

I know I’m going to get asked 1,000 times why would I ever want to sell the ShopBot? It’s been a huge part of what I am and what I’ve been capable of, not to mention one of the primary tools I’ve been using to earn a living, for almost 20 years. Well, it’s complicated, but essentially, I’m ready to no longer be the person that runs the machine. Or that even employs the person who runs the machine. I’m ready for a simpler, less stressful stage of my life where my income is not tied to how many hours I have available to work in the shop, or to being able to keep a bunch of other people productive and out of trouble.

      In a nutshell, here are the  Top 10 reasons to sell the ShopBot too

10.  It’s a good time to be selling good used equipment. Adding the ShopBot to the auction increases the overall interest in the auction and may lead to increased activity on the other items.

9.  Combining the additional auction income with saving the time and cost of moving the ShopBot to the house and setting it back up, I would have to bid and execute a lot of work just to repay the initial cost of keeping the machine

8. We may be selling the house in the next year or two and the machine would have to be sold or moved again

7.  I can still sell profitable work and have other shops cut it

6.  I know at least 6 other businesses that own CNC machines that I can call on to cut whatever I might need

5.  Selling the machine will force me to be serious about moving on to the next phase of my life

4.  I need to concentrate on less physical ways to earn money, preferably some that earn residuals

3.  I want to spend more hobby time with my wife and less time in the shop

2.  I won’t miss the noise or the dust

1.  It’s only a 4×8

My first ShopBot selfie!

Memories of my ShopBot will always bring a smile to my face. It’s been about the most reliable piece of machinery in the shop.

You might notice there are no traditional woodworking power tools in the auction. I still have all of my personal tools and basic woodworking equipment at the home shop, so other than not having my own CNC (at least for a while) my capabilities have not diminished, but my motivations and desires have changed.

So will this be my last column? Maybe and maybe not. I still have plenty of photos of projects I’ve cut that I haven’t written about yet, and just because I have a plan doesn’t mean it will work out exactly as expected. It rarely does.

Former ShopBot COO Takes CNC to the Woodworking World

Interview from 2014 IWF in Atlanta, GA

ShopBot’s former operations manager, ‘head camp counselor,’ and the penultimate editor of American Woodworker, Randy Johnson, is out championing CNC to woodworkers across the country. As an enthusiast of traditional woodworking, Johnson caught the CNC bug and has become an inspiring proponent of digital fabrication, CNC, and how to bring it all into the woodshop. His new book with George Vondriska, CNC Router Essentials, introduces readers to the technology and craft of CNC with presentations focusing on Vectric software and highlighting ShopBot projects.

The book is organized to get new CNC users going quickly, leveraging the ease of use of VCarve Pro from Vectric, Ltd. and the best practices for introducing CNC, as developed by the ShopBot training team working with new CNC users over the last 20 years. There is a lot of good detail in the book with illustrations of dozens of projects from our shelves right here at ShopBot World Headquarters.

One of the last chapters in the book features a wooden box with a beautiful 3-D, domed lid that George, along with the WWGOA (Woodworkers Guild of America), developed as a ShopBot project. George produced a fascinating video that will step you through how the work was done and impress you with the CNC skills and strategies he has developed.

ShopBot Offers Free Training for Imported CNC Routers

ShopBot Tools is opening its highly-regarded webinar training to owners and operators of imported CNC routers. Whether you bought an imported tool on eBay, or purchased from a US importer of Chinese tools such as Laguna, ShopBot invites you to join us for our online webinar trainings.

We’ve come to recognize that some importers (and even some US manufacturers) feel that once they’ve shown you how to start and run your CNC tool, their responsibility ends. We know that several dealers even boast of a short, “free” training session for their tools.

But as anyone familiar with CNC tools and digital production will tell you, taking a file to a CNC and starting it up is not the toughest part of CNC. Rather, it’s the conceptualizing and executing efficient CAD/CAM projects, and integrating digital fabrication into the production process, that can be a challenge to any shop. There are just a lot of interesting components of CNC to learn about – from design concepts to machining issues to material-holding. You’ll want to be able to develop an efficient workflow that fits your style. Everyone can benefit from access to key production information and resources. ShopBot would like to help … particularly shops that are just getting started with CNC. We can help new users avoid a lot of frustration. We recognize that the value of CNC is often less related to how much it weighs or what you paid for it, than whether you can put it efficiently to work in your facility. We’ve trained a lot of people to operate CNC routers over the last 20 years – we have a pretty good idea how to do it.

ShopBot is positioned to help because we design, develop, and manufacture CNC routers ourselves, right here in North Carolina, and not just the machines. We make the software, the electronic controls, and the tools themselves. So we know CNC from a lot of different angles. Maybe even more important, in our own shop we use CNC and digital fabrication across the entire manufacturing process. Our tools are digitally modeled, digitally prototyped, and digitally manufactured using CNC. We have a strong commitment to digital fabrication and robotic production assistance and believe it can be the key enabler for realistically competitive small manufacturing.

How to join the training:

And, hey, why are we doing it?

ShopBot’s CEO, Ted Hall, has stated:  “… If we can provide the training and resources that others are not offering, we feel like we are helping everyone in CNC, including ourselves. It’s that old ‘raising the water level’ thing.”

Non-ShopBot owners are also welcome to sign up for our in-house and regional trainings. In attending one of our trainings, whether online or in-person, you will also learn about items available in our web store—bits, accessories, and other supplies—most of which are appropriate for all CNC tools. And, ShopBot also offers CNC production services and consulting that can be helpful in setting up production with any CNC equipment.

Reports suggest that only 20-30% of production shops that could really benefit from CNC or production robotics are putting these to use. We have been making the case for years that it is robotics that will give the small shop and small manufacturing the chance to be competitive again. ShopBot is happy to lend a hand to all new CNC tool owners.

Building Boats, and a River to Float Them On

Assembling the Weekend Dinghy

Imagine being a high school student and having the opportunity to pilot a plane or a boat, learn how to design and model planes and boats, and understand the businesses behind the aviation and marine industries—all while taking core high school courses. Davis Aerospace and Maritime® High School, a unique partnership between Cleveland Metropolitan School District and PHASTAR Corp. presents that opportunity for students in Cleveland, Ohio.

In April, under a contract with TIES, I was able to spend two days at Davis to work with the teachers and digital fabrication lab managers. Our goal: to use the ShopBot CNC router (a PRSalpha) to build boats and create a model of the Cuyahoga River to float them on. Doing the research for how to make that happen was part of the fun.


PROJECT 1: Building Models of Boats

Danny and Nick, digital fabrication lab managers, showed me the progress that they had made translating designs on paper into models of boats. As shown in the photo, cutting out the models by hand, then taping the models together, regardless of how the plans were generated (photocopies or CAD drawings generated from paper copies), had its drawbacks.


First attempts at creating models from paper plans.


Joining Long Pieces Together
Once a CAD file of the designs had been generated in Fusion 360, Danny and Nick (with Scott acting as cheerleader) had used the ShopBot to cut out a sample in plywood. With the intention of eventually making boats bigger than either the bed of the 4’ x 8’ ShopBot or a standard sheet of material, they had created their own version of a scarf joint. It was a great idea to use the precision of the CNC to create curves to interlock and join shorter pieces into longer panels. But there’s more!

Bill Young, a boat builder from Virginia who early on realized the potential of CNC woodworking, would add another dimension to the scarf joint. For his boat kits, he created scarf joints that beveled the edges of the material where two shorter pieces joined together to make a long panel.


Scarf joint options. Straight butt joints, or beveled edges.


Then, Bill realized that he had the option of 3D carving (though he didn’t call it that) the scarf joints to increase the precision of the fit, reduce the chance of breaking off the tips during shipping, and disguise the joint in the finished product. Here is a link to Bill’s blog about his creative technique for creating “wavy” stepped scarf joints.

Holding the Parts Together During Assembly
Stitch-&-glue is a technique used by many boat builders who are creating “hard chine” boats: Panels cut out of flat material are designed or lofted with “developable surfaces” so that the curves of the panels will fit together when “folded” into 3D boats.

With a CNC machine, the panels can be cut very precisely so that there are no gaps or overlaps between the edges of the panels. As the panels are being cut, a series of holes can be added so the panels can be “stitched” together with cable ties until they have been glued in place.

Once again, I looked to Bill Young for inspiration. A number of years ago, Bill had created a file to cut a 1/4 scale model of the “Weekend Dingy,” a 9’ skiff designed by Karl Stambaugh of Chesapeake Marine Design. The original skiff was built during several of the Woodenboat magazine community boatbuilding events, and Bill’s model kits and instructions were given away during the early Maker Faires. For this trip to Cleveland, Bill was able to find the original .sbp files, convert them to a .dxf, then import them into a Vectric file for us to try out at Davis.


VCarve Pro or Aspire CAD file generated from original .sbp code.

  • In the ShopBot Control Software, the FC command will convert a .sbp file to a .dxf file. That .dxf can then be imported into the Vectric software.
  • The .sbp file includes the compensation for the waste from the bit. To get the true size of the design, the vectors that mark where to cut out the parts have to be offset to the inside the radius of the bit used in the original .sbp file.
  • Anything that is just a plunge into the material, like a hole for the stitches, would not have to be offset.
  • Once the true size of the design is determined, the model can be scaled up or down and re-toolpathed to take into account material and bit size as needed.
  • Note the layers in the design file. Many of the layers were created from the .sbp to .dxf conversion. Some, Bill created to keep track of his work


At Davis, we first scaled the model even further and tested the concept with tempered hardboard, easily available from the big box stores. Using a 1/8” bit, we used the drill toolpath to create the marker and through holes for the stitching (the size of the bit determines the size of the hole), and the profile-to-the-outside toolpath for cutting out the pieces. Didn’t quite get the cut depth correct, but not bad for re-engineering a 10-year-old file.


First test and detail of smaller model cut out of 1/8” tempered hardboard.


For the ¼ scale model, we used .25” inch Luan, again from the big box store. Without the vacuum hold down table and template that Bill had used for his Maker Faire kits, we marked where it was safe to put a hold down screw in the CAD file, had the ShopBot run a file to mark those locations on the board, and screwed the board to the sacrificial table. Since adding tabs to hold the parts in place while they were being cut out might mar the clean edge of the cut, we instead added a ramp to the profile toolpath to create a temporary functional tab at the start point of the cut. Nick also provided a physical assist to keep each piece in place while the cuts completed.


Vacuum template used by Bill Young for original Weekend Dinghy kits given out at Maker Faire. One could create a mini vacuum table much like the one described here, lay a template like this on top, then the material. When the parts are being cut out, the toolpath cuts into the template, and the parts are held in place by the vacuum.


Nick is using a board as an assist to hold the parts in place as they finish cutting.


Parts ready for assembly.


Members of the after school club assembled the boat using cable ties and intuition. (So why did Bill provide instructions?)

The school now has a project that they can share with their students, and with the community at large. It was also a terrific opportunity to revisit the ShopBot website for ideas and information about boatbuilding, including the original inspiration for why Ted Hall created ShopBot Tools.


PROJECT 2: A River to Float Them On

Danny and Nick showed me the 3D printed and laser cut boats the kids had designed, and a hand-carved model of a big bend in the Cuyahoga River lined with a plastic table cloth and fake turf. Danny reported that it was successful at first, but the plastic table cloth was water resistant, not water proof. All too soon, the water leaked out of the model. Still, the students were able to test concepts about size of craft, displacement and maneuverability around the objects, and geography of the river.


First attempt of creating a model of the Cuyahoga River in downtown Cleveland.


With the ShopBot, Davis wanted to create a bigger version of the Cuyahoga River to test larger models. Adding semi-realistic information on the depth available to float a water craft, and the height of the bridges they have to get under, would make the model more meaningful.

The first step was to locate a digital model of the river that flows through Cleveland and into Lake Erie. I tried Terrain2STL, a website that takes information from Google Maps and turns it into 3D files that can be printed with a 3D printer or 3D carved on a CNC. Cleveland is too flat for much detail, and the site wouldn’t give underwater data either. I also looked at Google Maps, USGS (US Geological Services) for topographic information, and NOAA (National Oceanic and Atmospheric Administration) for a chart of the Cleveland area that would be useful for mariners piloting Lake Erie and the Cuyahoga River. No one source was sufficient, but combined, they gave us a lot to work with.

Once we got a semi-clear image of the banks of the river, we brought it into VCarvePro for tracing. With the vectors, we could select the portion of the river we were interested in, and scale it for the size of material we have available. For our first attempt with a small piece of pink insulation foam, we were ready to use a pocketing routine and a ball nose bit to scoop out a model of the river.

Pocketing the selected area at three different depths with a ball nose bit and a large stepover using a contour path (hence the visible lines).


Since the model was a 2D vector and not a 3D rendering such as an .stl, with VCarve Pro, in this first attempt, we could only use 2D toolpaths that machine to one depth. However, the Vectric softwares have a toolpathing option called Fluting that will vary the depth of a single open vector from one end to another. Simulations indicated that, with a little manipulation, it would work to give us a river that was shallower upstream, and deepened as it neared the mouth.


Using the Fluting toolpath to vary the depth of the River

  • We created a series of open vectors inside the boundary of the river, and made sure the start point of each vector was on the upstream side (green point)
  • Choosing all of the vectors, we set the start point at 0  (top of the material) and the flute depth to 1 inch
  • Fill in the blanks, toolpath and simulate to check the results.
  • Adjust as the simulation reveals more about the results


The Professional Development was directed towards the faculty of the school. It was fun time when, each day, students visited the Fabrication Lab while we were working. Some even got involved in doing a quick project.

Students design and machine their individual signs. It was terrific to see how well Scott knows his students, and what motivates the reluctant ones.


This year was the inaugural year for Davis Aerospace and Marine® High School, starting with approximately 60 students in the 9th grade class. Each year will add another class until there are 4 classes/years. Applications for next year’s class are now open. I’m sure Bill Young (and I) would be glad to visit again and keep up with the progress.
