Hey all: I have a question for the group: I have a bench grinder that I'm trying to use with a buffing wheel. I picked up a shaft and pillow-blocks for free, then went to the store and got a 2" and 4" pulley for a 3450rpm-1725rpm step-down. I also picked up the *A* style medium duty belt the salesman suggested. I set it all up it won't work at all. The grinder can't get close to it's regular rpm. The grinder was made buy Albertson & Co Souix City IA. It weighs maybe
60 pounds, it's old, and says 1/4 hp. The pillow-blocks are shimmed up so the shaft swings freely. So my question is: Am I expecting to much of the grinder? Should I use a lighter more flexible belt? Am I doing something obviously stupid? Any advice would be welcome. Dean
