Flat top vs. Kettle top UDS
Hey everyone I have a question for those that have built a few UDSs. Between keeping the original drum lid and using the kettle lid which would you recommend and why. And to keep things easier let's assume the kettle lid fits snug on the UDS.
I'm thinking the kettle lid would be better just because it gives me more space for my top grate, but are there advantages for the flat lid I'm not seeing?

For one, the domed lid does not drip back on food.

I have no experience w/ a flat lid. I went w/ the Weber lid for the room and I'm glad I did.

If you have a domed Weber lid available there is no good reason NOT to use it. I have a kettle- and a double grate setup on my drum. I've used the dome lid to run 2 grates a few times. Jacking with 2 full grates on a uds can be a bit of a pain- so I don't do it often. I have my drum set up one 3 bricks with a slight cant, the "drip down" from the flat lid is not an issue.

Depends on what you want to do with your drum. I have one of each. I prefer the flat lid, But I also do pizza's on mine and the flat lid I can get a more even cook top/bottom with the flat lid. So the dome is strictly for smoking. I have 3 racks total in each. The bottom rack/grate is for a drip pan or deflector when required. 2 racks for cooking. Plenty of room even with the flat lid for doing 6 large butts 3/ea grate. I haven't had a problem with stuff dripping off the lid with my lids, either one. But I do flake off the extra when it's there.

Thanks guys, ebijack your post gives me a few more questions. I was also thinking of adding a grate for a deflector. What did you use for your deflector, how high above the charcoal basket is it, and when/how do you decide if it's necessary?

The flat lids do? :confused: They don't in the years of using mine. Perhaps your dripping was from a bad fire and was condensation.

^^^ same here^^^ Must be using a Water pan??

I've had condensation build up on my flat one with out the use of a water pan. For the deflector question, I used a pizza crisper pan from walmart with larger holes drilled into it. I kinda quit using it tho.

Any condensation is from a poor fire and convection.

Dome or cone lid, allows you to add another grate. Plus adds a little more distance from the fire basket for all grates. Further from the heat source in the drum, the better IMO.

Here is my uds. I use a stainless steel pan for a deflector. I use it everytime I cook and I never put water in it, I just wrap it in tinfoil. My advice is find a drum that a weber lid will fit on without any modifications, to me it's worth the looking around. 22 3/4 inch diameter barrel. I put my grate for the deflector 1" above the top of my fire basket. Build one with two cooking grates that way if you need it you have it. I put my top cooking grate 2" down from the top of the barrel and the second cooking grate 6" down from the top cooking grate.

Thanks for the pics dad2jsc. I just found a drum that the weber lid fits perfect on. The problem is it has a sealed lid. I know I can rent a jigsaw from HD for $15 but is there any other way to get that thing off. Keep in mind I only have a power drill, I thought I might be able to drill holes around the outside until it comes off and if that doesn't work then go get the jigsaw?

dad2jsc 06-28-2015 01:05 PM

Mine had a sealed lid too. Drill a hole in the top of the lid big enough for a metal jig saw blade to fit, then cut around the top. I used a sawzall with a metal blade. Jig saw would work but I think a sawzall works a little better.

Find some one with a plazma cutter or go to a welding shop and have them do it to get a cleaner bur free edge so you don't cut your self on the burrs IMO safe as to sorry
