tinyfish, perhaps you could use one of these instead of the food processor. I've had one for maybe 5 years and it works like charm at grinding meat, grating cheese, shredding potatoes, and much much much more. It had a stuffer but I have not used that because I have a dedicated stuffer. The stainless steel is thick and heavy, I think Dennis built it. It is not cheap but has tons of power and I expect it to last umpteen years. There are no gears to strip either. They are not available in many places and I bought mine from this site. Excellent service. It's funny many years ago I bought a Braun and all the attachments and found that they didn't work all the well and vowed never again to buy all the attachments. Needless to say I broke down and very glad I did. I do have most of the attachments including the pasta roller and cutters, awesome. Can you tell I'm a fan;)
