Thank you everyone for the kind remarks. Since this original post, I did end up getting a 5lb hand crank stuffer. I forget the brand. It works much better than the KA attachment. The last batch, I decided to do 10lbs. I think in getting much better but still have some questions. First, the casings seemed to be getting kinda of stuck on the stuffer tube. Is there like a good grade grease people use at all? Second, I'm still getting a little air bubbles in the links. When I first begin I pump out enough sausage out through the casing before I tie the casing off, but still seem to get air bubbles. I prick all the sausages when I'm complete with a sausage pricker, but I've heard it's there air in the casings that can cause bacteria. Do I need to worry? Any suggestions? Thanks in advance.
