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. (Maybe....Lol)

I'm very happy with a single BGE sliding vent. Very easy to slide with your foot, can use it to clean out ashes if need be, and allows easy access for a wiggle rod.

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!

I have a 3" makeshift daisy wheel and very pleased with temp range I get. No figuring out which cap, which valve to open or close. Just one to deal with.

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.

I did one 2" and love it. But if I did one again, I would consider a sliding vent like Jim did.

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

Plus it would be easy to hook up a Guru. I might have to look into this mod.

That's what my two BDS's have and work fine for me. I even drilled a smaller hole in the center of two plugs to give me more fine tuning on the intake.
