Some years ago I built a homemade grinder, using a #32 grinder and a heavy duty 1/2hp electric motor. I have a 1.25 inch pulley on the motor and a 8.675 inch pulley on the grinder. My RPM now is about 250. Grinds great. I can put fist sized hunks of meat in and it tears right through it.
Now I've decided to try to run my second grind right in to those heavy plastic burger bags. The stuffing tube for the bags is quite a reduction down from the #32 head, and my speed is so fast that I am over grinding the meat before it can be pushed through the tube. I am going to run another set of pulleys to slow the grind speed down. I am thinking of something in the ballpark of 70 to 75 RPM. Anyone with some experience have any other thoughts? Thanks, Al
