I bought a couple Landjaeger kits from PS to try in the smoker. This spice kit does 12.5lbs of meat but you need to buy casings separately. Thanks to Wea300mag and dogtuk for offering tips.
In an effort to make them fairly uniform, I cut the casings into pieces about 15 inches long. I probably stuffed them a bit too much at about ¾ full but they were able to flatten ok.

To flatten I placed them on cooking sheets, covered with butcher paper and placed another sheet on top. It was about 38 degrees in our covered patio during the day so I weighed the sheets down with a 5-gallon bucket full of apples. At night, when stacked in the fridge I put a 13lb pork butt on top.

I set them under a fan for an hour then flipped them over for another half hour.

About two hours in the smoker.

I will update later tonight as it finishes.
