UDS - quick question re. intake size

Porkchop · 06-16-2011, 07:40 AM

I have a 1 1/4" (36mm) ball valve and I'm hoping to get away with using it as the only inlet for a UDS which will also have a weber lid. Will it allow enough air intake to run a UDS? ...would a small riser welded onto the weber lid to create some draw help to maintain adequate airflow?

...thanks

I have 3 3/4 inch ones on mine and i have never needed to open up all three for normal smoking. But where you might run into problems is doing chickens and stuff like that at hotter temps.

I have (1) 1" valve and (2) 3/4" holes. When I'm smoking the wholes are capped and the valve is about 2/3rds open. That keeps me in between 225-250. So smoking you should be fine.
The only problem I could think of is when you're starting it up. I like to get mine up to 300 before I damper it down to my desired temp. I do this by opening all my intakes. Now this is just the way I do it, and it's definitely NOT the only way, or the right way to do it.
I would say, if your unsure about it, give it a try! Season it up and test it out. (Make sure you let us know if it works for ya)

FYI: With my 1" valve completely open (and the other 2 capped) it gets to about 300.

Thanks for the advice, I feel more confident going with the valve I have now.... I can always add an additional capped nipple later if needed.

I'm going to try out a few ideas of my own in the design of this UDS. I don't want to go into detail now but I'll post some pics and details once it's built.
