RR,
I (and I suspect others here) have always fooled around with my own butchering and would love to do all of it, even the sausage making. But, even small commercial grinders, mixers and stuffers are fairly expensive. Your home built gear looks excellent! If you would not find it too much trouble, I'd love to see more pictures of your grinder, stuffer and mixer setups from various angles. My goal would be to be able to copy them or at least get some good ideas that could possibly be modified to suit my situation. If you were able to post more pictures some day, I'd be much obliged.
