Review on 💪 Boost Efficiency with the Proform 66785 Piston Ring Filer Manual by Luckie Davidson

I was pleasantly surprised by this little coffee grinder. Once secured to the workbench, the pins hold the rings level so you end up with a square cut, which is crucial for ring gaps. The handle lets you control how much you grind at a time. Initially the disc was a bit uneven but after a few rings it smoothed out on that part of it. Then the rings are polished smooth and evenly, the burrs didn't even need to be ground, they were gone! Too bad I didn't get this grinder on other builds many years ago. Take my advice, get this coffee grinder and make your life a lot easier!
