Inertial Load Testing

A project log for Grinder Minder

Bench Grinders are everywhere. So are fingers. May the two never meet. That's where grinder minder comes in.

Captains log, supplemental. You may have seen our first dry test in a previous log and you were probably thinking "C'mon, there wasn't even a mechanical load on that thing!?" Well this clip is for you. We built an inertial test rig, which is basically a 10lb 10" flywheel enclosed in a protective screen to prevent it from decapitating us. Considering that angular momentum is proportional to the square of radius, and that this wheel is almost double the combined mass of a bench grinder drive train, it's a big test. Check it out.
