Temp was 250° at 4:30 and 5:00 pm - rock steady. I think I just need to catch my temps coming up a little quicker (say maybe 170° next time) and I can keep it humming along at 250°. At 5:00 I opened the ball valve all the way and took the caps off of the nipples, and it jumped up to 300° in 10 minutes. Gonna check it again at 5:30, and if it's at 400° or more, I'll cap the nipples up, adjust the valve to half-way again, and let it simmer for about 30 minutes to season it, then I'll shut everything up to let it die out.
I have to say that I'm actually very impressed with how easy this drum is to control. I know, I know - the Mother of All UDS Thread is full of success stories. I'm just happy to see that it works for me in real life just as easily as it does for other folks.
Lesson learned? Some things are just as easy as advertised.
