Makes sense. I do not add fat to hamburger, so that would remove the need for a second grind. When we make sausage I cut the chunks (meat and fat) pretty small and then mix the seasoning in with the chunks and mix really well. We then set in the fridge overnight, place in the freezer for an hour or 2 before grinding, and then grind a single time on the fine blade. It has worked really good without the PITA that is the 2nd grind.i do a large grind then mix things up again and do a fine grind. It just tends to mix the fat that I add to the meat better. After the first grind there are usually big chunks of fat still separate from the venison. This probably would not be a problem if i cut my chunks smaller and was not lazy and mixed things better to start but with the bigger grinder i can run pretty large chunks of meat through it so .... the second grind works great. Also if I am doing sausage i do a rough grind, add my seasoning then do the fine grind. Not sure if that is the correct way but its the way I learned and it seems to work.
