That is the only casing that I have ever used. I can buy hog casings just about anywhere around here. I just bought a bundle (enough to do 150 lbs of sausage) and it was only 4 pieces. These bad boys were real long.
Thats funny you say that. I called it the Outhouse. I have a lock on the door. Just so that when the kids are playing, no one gets locked in with the latch on.
PM me your email address and I will email it to you. I tried to upload it, but I can't.
I move the sausage in totes from one place to another. Its a bit of work. I like your idea. I might use that when I build the permanent smoke house.
