Well Fritz..After looking at your jerky and talking a bit with you I tried to make some too! I only made 5 pounds to start with..The one mixture of the 36 hour marinade was about right to cover 5 pounds..You must make a lot for 20 pounds..lol I am in my 7th hour and 3 hours of smoke. Its a little greasy and a little thicker than 3/16" Its top round. A thin piece was about right in 6 hours..the thick might take 8+ hours..lol Im steady at 163 degrees..My home made Grainger controller holds +/- 3 degrees. I am going to try to upload a couple of pictures of what I am doing.. Here is the finished product..8 1/2 hours..a little thick probably..
