Question: When you folks do a no weld UDS, how do you add the vents and valves to the sides?Once you have drilled the hole, I assume that you just thread them in through the steel with a pipe nipple, or maybe use a jam nut on the inside to draw them tight?
One of our freight accounts is a large container company, and they have new, unlined heavy guage drums with removable top and ring clamp for $25. I already have my first Weber still in the treasure pile (thank heavens it missed the last rip to the scrapyard when I replaced it with another one) and the grate and dome are in good shape. Heck, as long as a new drum is cheap, and I have a bunch of the fixin's sitting here, I probably should build me one of these critters for the sake of experimentation.
For my no-weld UDS, I drilled 4 holes for my intakes using a step bit. I was careful to drill the the holes large enough for the pipe nipples to fit, but small enough to where they would thread in tightly. I also used conduit nuts, one on the inside of the drum and one on the outside, to snug up to the drum to hold the nipples in place while screwing on & off the valve & pipe caps.
$25 for a new unlined open top drum. That's a great deal. If I could come across that deal, I'd pick one up right now and build another.
