Liberty Machine – Featured Customer

Liberty Machine, Inc. is a small Aerospace and Defense-focused machine shop located out of owner Seth Madore’s garage in Gray, Maine. In just a few years, Liberty Machine has transformed from a side hustle into a full-fledged machine shop with customers all over the world.

We were given the chance to visit Seth at his shop in Maine and interview him for this post. We picked Seth’s mind about entrepreneurship, the online manufacturing community, some interesting home construction choices made to accommodate a machine shop, and more.

Thanks for having us come out and visit the shop for this Featured Customer post. To get started, tell us a little bit about Liberty Machine’s history, and what sort of products you typically manufacture.

I founded Liberty Machine, Inc. out of my garage about 6 years ago while I was still working full-time at one of Maine’s largest (and best) Aerospace and Defense shops. I was working close to around 80-100 hours a week, maintaining my full-time job as well as coming home and making chips in the evenings and weekends. At first, I was doing a lot of smaller pieces and one-off parts, such as fixtures and prototype work to help build up a customer base and make enough money to eventually upgrade my machine.

In the early years, I was using an old 1982 Matsuura MC-500 Mill that I picked up for around $6,000. I used that machine to generate enough cash flow and eventually pull the trigger on a 2015 DMG Mori Duravertical 5100 with a 4th axis, probing and high-pressure coolant which really allowed me to take on the type of aerospace and defense work I had been doing at my day job and make the leap into full time entrepreneurship in my own shop. Now, we have the capabilities to focus on aerospace and defense work for major clients all over the country.

We are still working out of my garage, with myself and one other employee, but there are hopes for further expansion in the future as we acquire more work and expand our customer base. If you want to keep up with our shop, follow us on Instagram @liberty_machine!

You have a great shop here and are definitely maximizing the space. How much square footage are you working with?

Currently, we are working out of a 940 sq/ft shop. We “technically” have room for one more CNC mill if we really squeezed things together. I don’t think that is in the cards though; it is more likely that we will move to a larger space if and when the time comes for expansion. Heat management and air quality are real issues when working in small spaces with low ceilings, which is something we deal with currently.

What sort of machines and software do you have here in the shop?

For now, we have two VMC’s and a decent amount of inspection equipment. We have the DMG Mori machine I previously mentioned, as well as a 2016 Kitamura-3XD. Both machines have 12k spindles, Renishaw probes, and feature coolant through spindles.

For inspection equipment, we have a 2014 Mitutoyo QM-Height 350 Digital Height Gage, a 2003 Brown & Sharpe Gage 2000 CMM with Renishaw MIP Articulating Probe Head, and a 2003 Mitutoyo PH-A14 Optical Comparator. We also recently acquired a Scienscope Stereo/Digital microscope. This allows us to perform visual inspection of our parts at an extreme amount of detail.

Liberty Machine

There are still holes in our inspection lineup, so we are always looking at adding onto what we do to provide our customers with quality machined products.

For CAD/CAM software, we use Autodesk’s Fusion 360 as well as Inventor HSM.

You mentioned using Fusion 360 for CAD/CAM. Some of our readers may know you from the Autodesk CAM forums as an “Autodesk Expert Elite.” How did that come together?

About 4-5 years ago, I knew I needed a legal, supported, capable CAM solution. After several “30-day trials” of the more affordable packages, I stumbled upon Fusion 360. Having a fair amount of experience with Esprit and MasterCAM, I taught myself Fusion 360 in between running my shop and trying to spend what little time I had with my wife and children. Even though I had prior experience in other CAM packages, I still had lots of questions. I turned to the Fusion CAM Forums for assistance. The employees and other users were excellent to work with and got me sorted out quickly.

Liberty Machine

After I became more comfortable with the Fusion 360 software, I decided to spend some of my free time helping others by answering their questions on the forums. I wanted to give back to the community that had helped me learn. Autodesk eventually took notice of my constant presence on the forums and granted me the title of “Autodesk Expert Elite,” an honor given to some of their most prolific community members and advocates. Now I work with them to help test new features, provide insight from a user’s point of view, and participate in events like Autodesk University.

How did you first get involved in manufacturing?

I will be honest – I never meant to end up working in manufacturing. When I was a teen, I had glamorous ideas about law enforcement, federal work and so forth. But, life doesn’t always work out that way (I met a wonderful girl and goals shifted, so I started looking for alternate career paths).

My friend (future brother-in-law) was a machinist, so I started asking about his work and what it involved. He was working in a “job shop” using all sorts of cool machines and technology I had never really heard about. I was very excited about this career shift and I pursued it with fervor. 19 years later and I still LOVE this trade. The thing that intrigued me most about manufacturing, and the real reason I became so fixated on the trade, was the integral role the machinist plays in every aspect of manufactured society. I believe it is the most fundamental profession there is, and I take great pride in it. The evolution of the trade from manual machining to skilled programmers running CNC machines has always fascinated me as well and has kept pushing me to learn more and continue growing as a machinist.

Liberty Machine

Is it true that you built an addition to your garage specifically for the DMG Mori machine?

That is true! Before I bought the machine, I knew it was going to be too tall for my existing space, and was also going to need a solid foundation to sit on (it weighs 7 tons). Before the machine arrived, I had a concrete slab poured right against the side wall of the existing garage, and placed the DMG Mori on that slab.

After a couple days of unfortunate rain and multiple layers of tarps covering the machine, I had several family members (carpenters by trade) help me build the addition. Ok…I helped them. They were able to get it all framed and covered in just one day, breaking down the side wall of the garage and literally building the new space around the dimensions of the machine. Like they say, if there is a will, there is a way!

Running a shop out of your garage must have been a challenge to startup. What were some of the growing pains you experienced as this shop was built out?

On a professional level, the struggle was real. Two jobs, huge payments on the horizon, wondering where all the work (and money) is going to come from… As I mentioned, at that point, I was working 100 hours a week between the two jobs, and really feeling wiped out at the end of each week. However, the hard work did eventually pay off. Once I was able to get the DMG Mori and prove to customers that I had the capabilities to go full-time on my own, it was all worth it.

Liberty Machine

Outside of that, there were the literal growing pains, like cutting holes in my garage ceiling to fit the column on the Kitamura machine, and of course, building an addition to house the DMG. But like I said, it was all worth it in the end to own my own shop.

What is the best thing about working for yourself?

I’d say the best thing about working out of my shop (and for myself) is seeing my family on a daily basis. Yes, I still work 60-70 hours a week, but to have breakfast with them each morning before our day starts and have the flexibility to shift schedules around for doctor visits and other “life stuff” is worth its weight in gold. We are all so busy in life and I think we suffer as a society because of it. I want my children to know what it’s like to have a parent that is around. Busy, yes. But still present.

You mentioned that you had used a lot of Harvey and Helical tools at your last job. However, once you were on your own, you could choose any tooling you wanted to use. What made you stick with the Harvey Performance Company brands as your go-to tools?

The thing with Harvey Tool and Helical products that keep me coming back is the consistency of quality. I know that when I buy one of these tools, I am going to get a high-performing tool that has gone through multiple levels of inspection and is consistently ground within the tight tolerances that were promised. I honestly cannot remember a single time I have had to send any Harvey or Helical tools back for quality issues.

Liberty Machine

I tell friends and others in the manufacturing community about the tools, and the hurdle is always getting them to look past the slightly higher cost. That additional cost is always worth the payoff in the end knowing that you have a tool that will produce quality parts and shave valuable minutes off your cycle times. The slightly higher cost of the Harvey/Helical product is small change compared to the long term cost savings associated with their performance.

Can you remember a key moment where Harvey Tool/Helical products really saved the day?

Truthfully, Harvey and Helical are my first thought when I’m looking at a challenging feature on a new part. If they offer something that looks like it will work, I don’t even look for an alternative. Order it, get it in house. I’d say where Harvey helps the most is their awesome selection of long reach/stub flute end mills for stainless steel. I cut so much of that, so it’s great to have a vendor stock what is truly needed.

Liberty Machine

Would you recommend entrepreneurship to other young machinists hoping to open their own shop some day?

Yes! But like all things in life, “It depends.” Entrepreneurship is certainly not for everyone. The amount of work required to get a shop rolling and out of “crisis-mode” is insane. There is no other term for it. If you have a significant other in your life, MAKE SURE they are on the same page as you. I am blessed to have a wife by my side who sees the end goal and is understanding of the sacrifice needed in the short-term for the long-term benefit of our family.

What advice might you want to give to someone starting in this trade?

Don’t stop learning. Keep your ears open and your mouth shut. That old guy in the shop has likely forgotten more than you will ever learn. The amount of tools in your Kennedy box doesn’t mean you’re a good machinist. Some of the best toolmakers I knew had small boxes with only the common tools. Learn how to excel with limited resources. Ask questions, and own up to your mistakes.

Harvey Tool: Behind The Scenes

Many of our end users have had great questions about our manufacturing process, how we keep all of our tools in stock, and more. Now for the first time, we decided to open our doors and show you how we manufacture and fulfill the Harvey Tool product. We partnered with John Saunders from NYC CNC to create a “Factory Tour” video, covering topics like our CNC grinding machines and setups, tool manufacturing, and our warehouse organization and fulfillment procedures.

In the video below, we first toured our Rowley, MA warehouse and fulfillment center with Fulfillment Manager Megan Townsley. After that, we head up to Maine to check out how the Harvey Tool product is manufactured and inspected with VP of Operations Brian McKahan.

 

 

7 Facts Revealed in Our Factory Tour (Plus 3 More That Didn’t Make the Cut)

We know you’re busy making amazing parts, and might not have time for the entire video. To save you time, here are some of the highlights and facts you should know about Harvey Tool.

When We Say Miniature, We Mean Miniature

Our miniature end mills are in stock in diameters down to .001″. In fact, our Stub and Standard end mills cover every diameter from .001″ to .120″, meaning we will always have you covered when it comes to micro-machining. Although it is hard to see with the naked eye, you can get an up-close look at the famed .001″ end mill by jumping to the 35 minute mark in the tour video.

Micro-Tools Require Precision Grinding

We utilize advanced CNC grinding technology to manufacture our miniature tools at our plant in Maine. Brian MacKahan, VP of Operations, does an excellent job of breaking down our manufacturing process beginning at the 21 minute mark of the tour video. If you just want to see some miniature CNC grinding in action, jump ahead to the 26 minute mark.

Our Inspection Process is Rigourous

All of our tools are sent through an extensive inspection process, both at our plant in Maine and at our headquarters in Massachusetts. To check out the Massachusetts inspection room, head to the 19 minute mark of the video. If you want to see some more in-depth inspection at our facility in Maine, you can jump to the 35 minute mark.

Yes, We Have It In Stock

If you need it, we have it. All 20,000+ tools from our catalog are kept stocked and ready to ship to you the same day. If you need more proof, jump to 15:30 in the tour video, where you will see John Saunders choose a randomly selected Undercutting End Mill from our catalog and find it in our warehouse, in stock and ready to head out to a shop.

We Maintain a 99.8% Order Accuracy Rate

Our fulfillment team handles all of your orders with precision and accuracy. We maintain a 99.8% order accuracy rate, with fulfillment team members checking every order multiple times to ensure you receive exactly what you need. You can learn more about our order fulfillment process and accuracy rates by moving to the 5 minute mark in the video.

We Sell More Than Miniature

Miniature end mills have always been our bread and butter, but did you know that we have many larger diameter tools in stock as well? At the 9 minute mark in the video, you can see John pull out a 3/4″ Long Reach Ball Nose End Mill from our shelves. If you are interested in larger diameter specialty tooling, jump to 12:15 in the video to check out one of our large diameter Corner Rounding End Mills.

When You Call, You’ll Always Talk to An Experienced Tech Expert

Though we didn’t catch it on tape, John Saunders was blown away by our tech team during his visit. He got a chance to pick their brains about a problem he was having and a few minutes later, he received a recommendation for the right compression cutter to tackle his unique operation. This tool was later showcased in one of his “Widget Wednesday” videos.

When you choose Harvey Tool, you will never get an automated system or countless steps before you are able to talk to a real person about your applications. Our industry-leading technical support team is available over the phones or via email every Monday-Friday from 8 AM EST to 7 PM EST.

Zootility – Featured Customer

Zootility prides themselves on designing products that blend art and function for everyday use. Everything from design to manufacturing to distribution is done at their custom shop in Portland, Maine. Utilizing laser-cutters, laser-etchers, and CNC Machines, their skilled team works 15 hours a day to carry out their mission to get their incredibly thin, extremely useful “zootilitarian” tools into pockets everywhere. Zootility was founded by Nate Barr and was launched on the back of a successful Kickstarter campaign for their first tool, the PocketMonkey. Nate has now expanded Zootility and grown into several more products and brands, including the “WildCard” Wallet (Pocket) Knife, “Open Beer Season” bottle openers, the popular “Headgehog” Wallet Comb, and their new line of “Tülry” multi-tools that disguise as fashionable jewelry.

We visited Zootility at their shop in Maine and talked to Nate and Chris, one of their CNC Machinists, about using Kickstarter campaigns to launch new products, the state of the Manufacturing Industry, machining in very tight tolerances, and more in this latest Featured Customer blog.

Thanks for having us, Nate! Tell us a little bit about your shop and how you got started with Zootility.

Nate: Zootility really started as a maker shop for our first product, PocketMonkey. The goal was always to take the idea behind the PocketMonkey and grow it from just a Kickstarter project so that I could expand the business. I also wanted to make sure that I was learning something new myself every step of the way; I wanted to understand how to make our products, so we could keep production in-house and use our knowledge to expand the business in the future. When we started, I was re-investing all of our proceeds back into the business, allowing us to buy more equipment and really build out the shop. Our shop is fairly unique, where we now have nearly total vertical integration across the board. The only thing we need to do now is buy an iron mine and get our own materials!

How did you come up with the idea for the original Pocket Monkey?

Nate: I came up with the idea for the Pocket Monkey one day while I was locked out of my apartment. I was living in Boston at the time, and I would run out every night to the stores around the corner to buy food for dinner, typically only taking my wallet with me. One night, the door locked behind me, and I was locked out, sitting on my front steps and wishing I had some sort of a shim to slip the lock. I started thinking what that would look like and how it could fit in a wallet for easy carrying and realized that I could add on more tools like bottle openers and screwdrivers while still keeping it slim enough to fit in my wallet. I had studied Mechanical Engineering in college, so I had the background to create what I was envisioning.

Pocket Monkey

You have used Kickstarter campaigns very successfully, not only to launch Zootility, but also to further your product line and expand the business. How was the Kickstarter experience, and would you recommend it to other entrepreneurs looking to launch a new business?

Nate: Our Kickstarter experience was great. We have raised up to $90,000 in a single campaign, and we have figured out a strategy that works for us. We found that if you set a reasonable goal that will allow you to cover start-up costs, say $25,000 rather than $100,000, people are more willing to take the time to invest. A reasonable goal gives people more confidence that the project will be funded, and that it will be successful, leading to more backers and more exposure; it is a great Marketing tool in that regard.

Kickstarter also levels the playing field for smaller companies like Zootility – I consider it to be “The Great Equalizer”. There is no longer a need to have tens of thousands of dollars for upfront costs when starting a business. You can spend a little bit of time creating the campaign and invest a small amount of money into that without taking the huge risk of throwing your life savings into an unproven idea. When I started Zootility, I was still working my day job and did not have the money to put up front, so Kickstarter was a natural fit. We have continued to use Kickstarter for new product lines because we are committed to manufacturing our products in the US, so Kickstarter campaigns allow us to validate new ideas and collect funds up front as we continue to grow the business. I do recommend it for all the entrepreneurs out there, and it has been a great tool that has contributed to our success.

You mentioned your commitment to manufacturing Zootility products in the US. What makes this ideal so important to you?

Nate: Let me start by saying that I think that Globalization is a good thing; it has pulled huge numbers of people across the world out of poverty. However, American policies have essentially allowed large corporations to gut the middle class by moving jobs overseas, especially in more rural areas. This has created unbalanced manufacturing and retail sectors. Personally, I believe things have gone too far, and standing behind our belief in American-made goods allows us to contribute to a more balanced approach to manufacturing. As with all things in life, a balanced approach is the best option. There will never be a time when 100% of goods can be feasibly made in America, so overseas manufacturing will continue, but bringing back more jobs to the middle class here in America is a good thing for the entire industry.

zootility

We have definitely made an effort to re-invest in our local community and the people who live here by manufacturing our products right here in Maine. Offshoring has resulted in a loss of knowledge and a real disconnect from the products that we use every day. Products that were previously considered to be of a high quality are now losing their shine, as less care is put into them and there is less appreciation and understanding of how these things are made. By investing in our local community and ourselves by learning something new every day, we believe we are doing our part to bring this knowledge back and instill more of a sense of pride in our employees and the products that they help to create.

You are originally from the Boston area. What made you decide to move the company and shop to Maine?

Nate: I had originally looked at a few places in the Boston-area, but it just didn’t make sense financially. There is a lot of great technology being developed in Boston by the innovative companies in the area, but to set up a manufacturing business in Boston was cost-prohibitive. By moving our shop to Portland, Maine we were able to save a lot on the space, which helped us in the early stages of the business.

The other thing was the lifestyle change. Portland has a great downtown area with lots of small businesses. There are restaurants, breweries, coffee shops, and plenty of locally-owned shops. It is also easy to get around, either by car or bike, and there is very little traffic throughout the city. I also wanted to locate our shop so that it felt like part of a community. We were able to find a great spot in downtown Portland surrounded by other manufacturers and small businesses. It makes for a great place to come to work every day.

What does the future hold for Zootility?

Nate: Right now, we do as much business in Q4 around the holidays as we do the entire rest of the year, so we have been exploring ways to make better use of the machines during the slower months. As we have completed installing and setting up our new machines, we have begun to do contract manufacturing to fill out the rest of the year. We have the unique ability to create small parts with extremely tight tolerances, and we are willing to do small volume, small batch manufacturing that other shops may turn down. We have been getting business from companies in Boston, who are looking for the “just in time” manufacturing which we can provide. The extra revenue from these projects will allow us to take off the Kickstarter training wheels and expand the business faster on our own.

tulry

From a product standpoint, we are looking to launch more “serious” tools for the outdoor enthusiast. Right now we are in the process of launching our new RNGR brand, which will be a line of minimalist every day carry products, without the whimsical nature of the Zootility Tools products. We also are on the verge of shipping our new TÜLRY brand, which is a series of jewelry infused with every day carry tools.

Chris, you create a lot of very thin products. How does that affect your workholding when working in materials that thin?

Chris: Our workholding has been built entirely custom for our CNC machine, due to the nature of the products. For example, we are currently working on our WildCard knives, which are only .040″ thick. There really isn’t much on the workholding market that will work well for something that small, so our team actually machined our own metal strips on the CNC, held the knives down with small bolts, added some rubber bumpers so we do not have metal on metal contact, and it has worked really well for us so far. We also created custom workholding for the new TÜLRY line tools, which are also extremely thin.

helical solutions

The biggest challenge with our custom workholding is the additional time it adds to each job. Right now, we can run batches of 72 knives per cycle, with a cycle time of 28 minutes. Then, we need 20-25 minutes to unscrew each of the bolts, remove the finished knives, and then insert the new knives and screw the bolts back in. However, it is the only way we can machine products this thin with our tight tolerances, and we can still finish around 600 knives per day.

You mentioned your tight tolerances. What are some of the tolerances you are working in every day?

Chris: Right now, all of our tolerances are in the thousandths. For example, the WildCard knives have a tolerance of just +/- .003″, and the screwdriver tools on the TÜLRY necklace, while one of our highest tolerances, stick to just +/- .005″. The tightest tolerance we are currently working in is on the hex wrench tools for the TÜLRY necklace. The hex wrench tools have to be spot on, or they will be too loose when they go to be used on a hex nut. Right now, we like to keep those tools to a tolerance of +/- .001″.

How has your experience been using Harvey and Helical tools on these projects?

Chris: The Harvey and Helical tools have been great for us. When I started, we had another brand of end mills in stock, and they simply weren’t cutting it (no pun intended) in the types of heat-treated stainless steel which we were working in. We switched over to the Helical 7 flute end mills for roughing and finishing of the knives. Each knife has a very small shelf on it, which allows it to be a removable piece of the WildCard tool. We use a 3/8″ 7 flute Helical end mill with a .020″ corner radius for this cut, with a 3/8″ 7 flute square end mill for finishing. One interesting part of this job is that it requires a very low ADOC because the tools are already so thin, that the roughing we do removes only a very small amount of material.

harvey tool

We also use both Harvey and Helical chamfer mills to create all of the box cutter and hex wrench TÜLRY tools. With the hex wrenches, we have found that the 60° tipped off chamfer mill has been great for creating those intricate cuts. With the box cutters, we needed an edge sharp enough to cut through tape and cardboard, but not sharp enough to cut through the skin. We have found that the 2 flute 120° chamfer mills work best for those cuts.

What is the biggest challenge you face at the CNC machine?

Chris: Right now, we laser cut all of the outlines for the knives from a thin sheet of steel. Then the knives come to us right off the laser cutter for machining. The laser cutting does create a rough finish on some of the knives, which can make them hard to lock down when machining. This can result in some movement, which can lead to the occasional scrapped part. The laser cutter can also leave burrs at the start and stop points, or leave a scorch mark or some slag on the knives, which can make them tougher to machine.

The Zootility shop uses a lot of different equipment. How has the CNC machine in particular impacted the shop as a whole?

Chris: Our CNC machine comes in handy for a lot of different things around the shop. As I previously mentioned, we used it to create our own custom workholding, which has worked very well for us. We also used the CNC machine to create all of our forming dies, which are used to create all of our tools from scratch. As we move into more contract manufacturing for other companies, these machines will get even more use when we are working on the small batch jobs we will (hopefully) be getting.

Harvey Performance Hosts Local Students for Manufacturing Day Tour

Harvey Performance Company welcomed dozens of local high school students to its Gorham, ME manufacturing facility for an educational tour as part of “Manufacturing Day,” a national day of celebration of modern manufacturing meant to promote, inform, and inspire.

As part of the tour, students were led around the facility by Harvey Performance Company engineers, receiving valuable insight on how a state-of-the-art CNC grinding machine turns a carbide blank into specialty tooling.  The event concluded with a question and answer segment led by Plant Manager Adam Martin.

“It was a thrill for me to meet with the participating students, and to see just how enthusiastic they were about manufacturing,” Martin said. “The Harvey Performance team really had a great time celebrating Manufacturing Day with them.”

harvey performance company

Nationwide, more than 2,800 events took place for current and aspiring machinists as part of Manufacturing Day, held the first week of October every year. In 2016, 84 percent of participants in a Manufacturing Day event were more convinced that manufacturing provides interesting and rewarding careers, according to data from Deloitte and the Manufacturing Institute.

Harvey Performance Company remains committed to its goal of highlighting the best of the manufacturing industry via its “Plunge Into Machining” campaign.
