jason.neucere So that was the premise we ran on initially when we found out that our mixer fit our old Weston grinder, however, there are some pretty serious caveats to that. The size of the housing around the gear can vary to a good amount, for example, ours is large than Weston uses so it will work from grinder to mixer in this case but not from the mixer to the grinder. Another big one is how to lock the heads in. Ours and I think Cabellas are both top notches whereas a few of the others are either below the notch or a different sized notch, so it will come very close to hooking up but not fully connecting the auger drive shaft to the chuck in the grinder that turns the auger.
