Looks cool! Think the minimal amount of air those small gaps would allow will have any effect?

It has potential. My concern would be the gaps at the top and bottom. Many people run their UDS with the ball valve just barely cracked open. I would also wonder if you could ever put the fire out completely with air still getting in.

Not sure there is much point in finding a replacement for a $9 ball valve..........

its a 2" pipe. My first UDS I had a single 1 1/2" and sometimes wondered if I needed more air. I am concerned about the gaps though. probably won't work, but I'll try it.

where are you getting a $9 valve? I can't find anything under 35-40 bucks.

well it looks cooler than a ball valve too. Almost like a carb for your drum.

He is probably referring to this. However, if you are looking for a 2" one then yes, you will pay a lot more. There was a reason that 3-4 smaller intakes were suggested and used on "standard" UDS builds.

I assume this is for intake? In that case most are using 3 x 3/4" pipe nipples. Barely leaving one of them open during the cook via the ball valve. 2" ball valves do cost a bunch more and that is likely why everyone uses 3/4". Not sure why your UDS would need that much intake open. I don't think that is typical.

i never understood this. You have three nipples, but keep two closed and one partly closed with a ball valve? So why have three?

My first UDS I went with a single 1 1/2" intake. Piped it up to the top and covered it to control air. Not sure I was really happy with that. I think the long pipe was messing with me. Building a second and decided not to pipe the air intake up to the top. Decided to use 2" this time. Figured I could always turn it down if need be, but if I wanted to turn it up for some reason I could.

the other reason I went with one the first time is I didn't have a good hole cutter, so cutting one 1 1/2" hole would be easier than three 3/4 holes. But now I do have a hole cutter. Maybe I should drop back to three intakes.

I use the extra intakes when I am bringing it up to temp or if the wind changes and I need intake from a different side. It is easier than moving the drum while it is cooking. I don't have wheels.
