so, finally finished my UDS
Here's my (blurry) UDS. A former apple juice barrel with a yellow liner. Removed the liner with a combination of wire wheel and burn.
One 3/4" vent at the rear with a screw-on cap, welded in, home-built sliding vent at the front with an 1-3/4" vent hole made from aluminum sheet I had lying around. Bent and shaped with a hammer, cutoff wheel, and a bench vise.
Charcoal basket is #9 expanded steel wrapped around a charcoal grate from a $25 Big Lots 22.5" grill, wired on with coathanger wire and welded along the seam (oxyfuel torch). 16" pizza pan for an ash pan. It seems fairly large to me, so it should hold plenty of charcoal for long burns.
The lid is also from the Big Lots grill, fits like a glove. No mods needed. I may re-use the wheels and legs from the Big Lots grill to put wheels on this thing, but I don't need 'em for now, I can use my dolly if I have to move it around.
Sanded the whole thing, sprayed the outside with high-temp paint.
Thermometer (not pictured) is a turkey fryer thermo from Walmart. Dropped it in boiling water to test, came up pretty darn close.
I only have a single grill in it for now, also from the Big Lots grill. I may add a second grill later.
Thanks for the thread, it was very instructive! I'm on-call to work on the 4th, so I'm stuck at home. I'll make the most of it with a maiden voyage of the UDS, a fatty, and maybe a pork shoulder.
