So I picked up a LEM #12 Big Bite grinder a few days ago and knew that I was going to get a stuffer. After making some fresh sausage today, the wife said to get a stuffer. I went with the LEM 5 pounder. My first question is about grinding plates. My smallest plate is 4.5mm, should I get the 3mm? Or is 4.5 small enough for hot dogs? My second question is what size casings would be good for my first time? If it matters. I have read the stickies, and read a lot, just kind of need a kick in the right direction.
