      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.

        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!

        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.

        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!
