Well, heck I'll play! I have a UDS 1.0 and just built UDS 2.0
UDS 1.0 has a 1-1/4" air inlet up the side of the drum made out of conduit and welded into place. It also has 3-1/2 "nippels welded 2" from the bottom of the barrel. the exhust was 3 feet high, but it was to high so i made it a 2" conduit 8" long welded in th bung hole.
the basket is 14x6 and the grate is 6" from the top of the barrel the legth on the barrel is 48" tall.
The UDS 2.0 has four 1/2" nippels, one of the nippels has a 1/2" ball valve on it. the exhust is a 2" inch conduit sanded down and buffed with a polishing wheel, and held in the center of the lid with a 2" EMT set screw connecter. The nippels are 1-1/2" from the bottom of the barrel and are held together by lock rings. the basket is 14x6 and the grate sits 6" from the top of the barrel. the barrel is 43" tall. My fingers are tiered from typing so enjoy the pics.
