During one of my regular Craigslist searches for a used 2” X 72” belt grinder I came across an extremely talented guy on YouTube who designed and built his own: https://www.youtube.com/watch?v=a_RlL1O-bK4&t=11s. It had never occurred to me that I could simply build one so I purchased a set of his plans and made a few minor mods. Ironically, I was building the tool that I needed to make the parts to build it. Through the process I learned quite a bit about 3 phase and variable frequency drives. The heavy gauge steel really pushed the limits of my hobby welder and it still needs a few more components but so far, the unit is rock solid! Thanks for the inspiration Jeremy.
