Well I couldn't let it sit without some meat on it.
Threw some hot Italian sausages on for dinner, had a little trouble keeping the heat regulated and it seemed to take forever to get the sausages cooked (3 hrs???).
Found two problems with my thermometers.
#1 The small thermometer I was using to measure internal temperature of the sausages reads low when you just stick the tip into the side of the sausage, jam it in from the end a couple of inches and it reads much higher.
#2 The thermometer I was using in the drum is from my turkey fryer. Decided to see how accurate it was and boiled some water, I didn't know water boiled at 250 degrees.
If I was running the UDS at 250 on the thermometer it was more like 212 degrees. That might be why it was taking longer then I thought it should have. Good news though the small thermometer I use to check the temperature of the meat was spot on.
