Hi all
Wondering if anyone has experience with UDS smokers? I've made one myself and had a few cooks but struggling to get long and slow cooks think due to air intake /exhaust issues? Current set up is a standard drum, charcoal basket raised about 15 cm from the base of the drum, basket is maybe 50cm tall x 40cm diameter. Currently have one 1 inch ball value and 1 inch nipple at the base of the drum for air intakes and a standard webber lid with the standard air vent openings. The rack for meat etc sits say 30 cm above the top of the charcoal basket. I've been using jarrah as the fuel for the smoker. Couple of bricks inside the drum to store heat and looking to get a metal pizza tray with to put on top of the fire basket to spread the heat more evenly.

Finding that I'm struggling to maintain even temperatures and sustaining the temperatures? Start the cook and the temperatures seem to go down gradually to the point where I need to move the webber lid ever so slightly off to stop the fire choking, then closing it as the fire gets going again, etc etc. I originally had only 1inch ball valve, then for the next cook added another 1 inch intake nipple, think this helped. Now thinking maybe the exhaust vent on the webber lid is not enough and I need to add more? Does this seem a good idea? If so what size should the vent be? Also how much wood do people add to their cooks and do you top these up or just add all at the start?

Want to get it so that I can leave the smoker running overnight for slow cooks eg bricket, etc

Thanks for any advice!

do you have some pics of your setup?
the weber lid should be sufficient exhaust. as for the 1" ball valve be aware that the inner diameter of the intake pipe is usually 3/4" and that the intakes (even with 2x 3/4" dont equate to the exhaust openings)
also, are you using minion method for the burning of the fuel is it lump charcoal or heatbeads?

if you are still having issues build a pit controller to automate your cook

Hey Mate, I have a UDS I built myself and works a bloody treat. I have 1 ball valve and 2 nipples on mine, usually I run it with both nipples capped and just using the ball valve to control temp.

What's you fire basket made from? Does it have plenty of holes to breath?

Just jarrah or you using charcoal/heatbeads as well?

Hi all
thanks for the advice, some photos of the set up, one 1" nipple and 1" ball valve, fully open, still having issues? Currently using just solid jarrah logs? Any further thoughts much appreciated

yep, cant use just wood in a UDS
you need to use charcoal or brickets

wood requires more air for combustion and runs at much higher temps for a clean burn

Aha that would be it then! Many thanks, any recommendations for brands of fuel to use briquettes, or should I try and track down some proper charcoal from a local source? (Based in Perth)

heatbeads are very controllable but any lump charcoal will also work.
Look up the minion method, this is what is used for a controlled burn
