Years ago my buddy and I hooked up an old 1/2 variable speed drill to a hand crank grinder to grind up a large batch of moose meat . Until we got the hang of the trigger, we had to hold the meat tray almost horizontal...the ground meat came out so fast . To liven things up a bit (when it was my turn to run the drill), buddy dropped a small bone into the grinder ...the torque practically threw me across the room ! He thought it was funny.
For quite a few years now , I've been using my old metal lathe hooked up to a hand crank grinder (a #8 Porkert)....but would be nicer to have a unit one could place on the kitchen table . I like the home-built one in SausageMania .
