trying to post this again...I guess it disappeared into the ether..
My shop made 2x72" belt grinder. Based on the Wilmont EERF grinder. I made several of the parts in my shop, but a few were too large. The big frame parts were water jetted at a local machine shop.
My overall cost was about half of buying a ready to run machine. It has a 1.5hp motor, 5" drive wheel, and 5" contact wheel. A cool project, and definitely going to be useful.
