The Revolution 2x72 was designed with the home builder in mind.

The tools needed to fabricate this powerful machine are very easy to come by (most have them already). The novice fabricator can put this together and have a versatile, feature-rich, tilting 2x72 Belt Grinder that would cost thousands of dollars if it were manufactured.

Get the Ultimate Bundle Kit and see how you can Revolutionize your home workshop with one of the most important tools of the 21st century. Also, you do not need any special work table for this, it will bolt down to any flat work surface and tilt with ease. 

The process of designing and building this grinder is a series on YouTube. For more details and a breakdown of the machine, Click here to watch the series.

      These parts will ship from our Florida warehouse. The steel is made in the U.S.A. and is laser-cut by a shop in Florida.

      Your Ultimate Bundle will ship in two (2) USPS Priority packages.

      One box has all the tube steel, hardware, and some plate steel, weighing about 62lbs.

      The second package is a sleeve with the motor plate and work rest, weighing about 14lbs.

      Orders go out within 2-3 business days. In most cases, we ship within one day (sometimes same-day!) and do our best to get everything to you ASAP.

      Customize it
      There's no limit on what you can do with a Revolution.

      Add tooling arms, small wheel attachments, glass platens, curved platens, custom work rests, and whatever else you can dream up.

      The Revolution Generation 4 grinder is the most modular industrial DIY beast on the market.

      Frequently Asked Questions

      Not yet. But we are in the process of working out ways to supply more of the components needed to finish the build.

      Stay tuned!

      No. We now grind the weld seams out of the tube steel for every kit, for the receivers that require telescoping pieces to fit into them.

      Not at this time. The Revolution is a full-on DIY project from the ground up.

      Not at all. We have had many Revolution builders learn to weld just for this project! And if you don't have a welder, maybe you have a friend who welds and owes you a favor...?  :)

      We’ve had skilled fabricators do it in as little as 4 hours -- but typically, most builders knock this project out in a weekend or two.

      • Base Plate
      • Work Rest (easier to build)
      • D-Plate (lower pivot point giving 2" more above the work rest)
      • now includes a tracking mechanism (parts, you have to drill and tap the holes)
      • All the builder has to source is the wiring (we now have wiring kits available here), wheels, motor & VFD. 
      • Optional Fusion 360 CAD file as an add-on.

      Customer Build

      I love this thing! The build was pretty straightforward. I followed the instructions and picked up couple new skills along the way. I'm not a knifemaker, I'm just an all around maker. This thing is a beast!

      I purchased the Ultimate Bundle with the plans and all the laser cut parts. That is definitely the way to go!

      I love the grinder. It went together like a dream and works perfectly. The tracking is super responsive.
