Finally read it all..
Well read it all, quite a read started on Tuesday joined last night so I could post today and finished reading today, my UDS is already done I actually found this thread after it was pretty well done off of just some pictures I had seen. I had the lid made for it it has a 2 3/8' OD pipe for an exhaust three 1 1/4" holes with magnets for intake, and a rectangle exp metal box for the lump, two grates, one is 5.5" from top other 10.5" from top.
I did a test burn yesterday and it worked great, ran a little hotter than I would have liked, but I think it was because my charcoal grate was over the 3" recommended height it was at like 4 1/4".
I kno I kno I'll put pics up soon and pics of the two bostons I am doing Sunday, smoker is at work camera is at home which is why I can't add pictures now.
