I made my first slims jims last night. I had everything set and the meat ready to stuff, so I thought. I had ordered 16mm collagen casings and a stuffer tube for them. I put the tube on the stuffer, but could not get the casings to go over the tube. Either I ordered the wrong size tube or they sent the wrong size tube. I found that if I pulled (unraveled) the casings, I could then get short lengths of it on the stuffing tube, so I stuffed 10 lbs of slims jims in approximately 6 to 8 ft sections. Oh well, when I was finished smoking them, I cut them into 8 inch pieces anyway. Oh yes, about 2 AM I ordered the correct stuffing tube.
