Game plan was to make some brats after finished processing venison. What the heck, grinder is out and dirty. I bought a used #22 Wesson that came with many different tubes for filling but did not verify having correct diameter. I know you pros use a stuffer but I was going to do like how we fill are plastic ground meat bags. I ran butt through plat with 5/8" holes then mixed seasoning in and in freezer. Mistake #2 was I mixed 10% cheese in then realized the only stuff tube I had that would fit 30mm casing was about 1/2" dia. No big deal just take a little longer. Installed 7mm plate and 1/2" tube and ran meat till tube was full. Looking good, slipped casing on tube, grinder on and nothing. More meat, cheese and nothing. Dont know if cheese was culprit and or 1/2" tube, but throat of grinder was 2LB of sticky gooey mess that no amount of plunging was going to get to feed through. 20 LB of ruff ground, seasoned pork butt sitting there, and im in panic mode. Was able to get about 3' of casing on my next largest tube at a time and 1.5 hours later finished brats. Running cheese through 7mm plate pretty much turned brats yellow. Live and learn.
