Brothers, I have a UDS that I have been using for several years. I built it with 3, 3/4 inch fittings for the intake and one, 2 inch hole in the lid for exhaust. I want to be able to get my temps higher than the 330 to 350 for extended cooking times, so that when I take it camping this spring, I can cook up to 450 or so for any baking needs. If I make a second 2 inch hole in the lid, do you think that the draw would increase enough to do that by its self or should I add a forth 3/4 hole? The biggest part of adding the fourth intake hole is that my OCD will kick in and every time I walk by, I am going to tweak and think "man I should have just added 3 evenly spaced holes". 6 intakes would also be a little much.

Go big and put a 2" ball valve on it.

I dont know....that is a huge space from charcoal basket to cooking grate. I dont care how many intakes i added to my UDS....dont think i could prolly ever get to 450. 400 could be a chore

I would try lowering the cooking grate and /or use lump.

Before you change anything.
Though I believe you will need more intake and exhaust.
Trying running pure lump and alot of large pieces of wood chunks to see what is the max temps you can hit/hold. Light up a full chimney to start. Put at least 4 chunks of wood ontop of your ready to burn lump basket. Leave the lid off for a few minutes till you get a hot fire going. Once you put the lid on, your temps will drop, then stabilize out.
Then you can decide your next step.

I have 4- 11/2" pipe elbows on mine for intake and almost 4" for exhaust. I also am able to cook to 750*+.

Have you tried adding more lit coals? And try screwing a short stack into that top hole on the lid.

You want more heat? Add a bit more intake and exhaust. Or just put your baking off until you get back to civilization. D Boone and D Crockett probably did not do much baking on their outings.

I hate to be the one to suggest it. But you need a 007.

I generally light the basket with a starter cube on the top, let it burn outside the barrel for 20 minutes, then put the basket in, top on and wait for my temp to come up. I will wait longer to put the basket into the barrel and see if that helps

I actually was trying to find the discussion in those the other day, after I started thinking about this

Or mesquite lump before a bigger intake/exhaust mod. Burns hotter, longer.

Use hardwood lump charcoal and/or crack the lid to the side a bit. You will have ripping temps. I light half a chimney of KB and when its starts to get gray and ashy I dump it into the middle of the fire basket where I have made a hole.

If you are really looking to bake while camping. These are the best. Lots of brands/sizes to choose from

A specifically built UDS will cook from 180* to 750*+. I've built a few. And now have a stubby 007 UDS that does the same.

If you shortened your 110 gal, I'd bet you would find it much easier to use/move without losing anything except being able to hang full racks of ribs.

Put a piece of 6" long pipe on each of your exaust holes to give it good draw / a house chimney has to be above the peak of the roof to have a good draw. Put 3 more intake holes on the bottom, I cover mine with fridge magnets when I don't need them open. Leave the exaust full open and adjust temps with the intakes only. IMO DouG M

As it is with the casters, the rim of the UDS is above my elbows. Makes lifting the lid and reaching in pretty awkward. But more awkward would be my finishing on cutting and rewelding the 110 gallon shorty.

So on this subject, I had to cut the two inch hole for my exhaust. What is the best material for this? I am sceptical about using the white plastic pipe with a threaded connector but it is cheap. I have thought about a threaded heavywall electric pipe with locknuts , but I think it is galvanized? I dont weld!

several choices come to mind.

Black malleable pipe floor flange and a nipple?

or an aluminum conduit hub:

Thanks! I hadn't thought about a hub. Never thought to look on eBay for an exhaust pipe either
