Earlier today I was watching an old episode of Forged In Fire. I kinda dig the show and I took notice of the belt grinders they were using. At first I thought they were multi thousand dollar pro units, but I noticed the interchangeable attachments had a home made look to them. I tried to do a google search and turned up several grinder plans that people use to build their own grinder. That certainly works with my budget! I was able to find two different grinder designs and both seem to have their own advantages. I've got a 1.5hp motor left over from a past project but these guys seem to be liking variable speed grinders. One design uses a belt and pulley to change the speed, the other builder uses a VFD to control the motor speed. VFD's are a really slick, but honestly, I'm not sure why there is a need to change the speed at all. Has anybody ever tried building a grinder from these designs? Was the outcome satisfying or prone to problems?
