Five pounds of snack sticks, five pounds of hot dogs, seven pounds of sausage Tiranno, five pounds of fresh garlic sausage and two pounds of chorizo all ground up and mixed this morning. I was going to smoke this weekend. It was supposed to be all mine. Two pounds into the sausage Tiranno, the plaskit gears on my Northern Industrial five pound vertical stuffer crumbled. It was really only a matter of time. It was actually long overdue. I should have had a backup. Next weekend will be different. Once I get replacement gears this week. My question: since many of these five pound units are identical, will metal gears from another manufacturer work on mine?
