This get's my vote for "Best Dirty Thread Title of the Year Award". Classic!
Back to question- I built my UDS with one big(1-1/2")pipe for the intake with ball valve. Works great and there's no bending over to adjust the air.
UDS, Akorn, Weber Red Head Kettle, Drum Grill, Gasser w/cobwebs all over it. I'm JD.
