I have 4 3/4" pipe nipples with one ball valve and 3 caps - I think I'm gonna go with 2 ball valves - if they were cheaper I'd run 4 ball valves........
If I build another one I think I'll do 2 larger intakes with 90* elbow and pipe riser- like 1" or 1 1/4" or 1 1/2" with ball valves at top of both.:confused: (Maybe....Lol)
I'm using a Guru Party-Q now, so I've redesigned my UDS. 2 1" ball valves, & a 3/8" valve in the middle for the guru. I've used it several times now in the new configuration & it works like a charm. Good luck!
Cheap and easy way - four 1" holes with refrigerator strip magnets
As far as number and size of valves can depend on the valves you use. Some valves have very small ports and restrict flow, I recommend finding valves that are "full port" so they don't restrict flow as much. If you decide to put the elbows and pipe risers I would go with 1" as people say that length of pipe restricts flow more. Otherwise I prefer 3/4" with either 3 or 4 of them, I have never needed more than 2 but I don't cook hot and fast, yet. The 1" fittings make you drill a large hole in relatively thin metal and feels flimsy plus at that size the curvature of the barrel starts to show and my fittings don't fit flush.

3) 1" ball valves

I did one 2" and love it. But if I did one again, I would consider a sliding vent like Jim did.
Sweet but it would look so much betta orange with a set of long horns:razz:

I would think you just want to make sure the intake area is larger than the exhaust opening(s).

wow nice cookers and good advise i think ill go with 4 3/4 inches holes 2 capped and 2 with the full port ball valves ill measure the total diameter of the barral and split it into 4ths and drill holes there 2 inches up from the bottom that should be enough air and control
