Weber lid on the UDS?

[rw willy]

I am proceeding w/this mod. I am looking for some help concerning exhaust. Should I drill 4 more 1/2 inch holes in the Weber lid to match the 8 holes in the UDS lid? Or stick with the original 4 holes w/ damper control?
I am leaning on leaving the original holes and drilling 4 more 1/2 inchers.
My concern is stale smoke from insufficient draft. Unstable temps due to lack of draft.
This is a mod that will not allow me to use the UDS lid after it is complete. I have cut 3 inches from the upper lip of the kettle portion of an old Weber. I will bolt this 3 inch band to the inner UDS. It will extend above the UDS lip by at least an inch. I will fill any gaps with gasket rope and silicone.
Any help would be great.
Thanks

I just used the original holes that where in the lid and did not add any more. Seems to work fine for me

Instead of bolting it to the drum, why couldn't you get it set in place and attach the gasket rope with the hi-temp silicone so it could be removeable.....??

Just an idea....

Just use the lid as is.

Not all drums are created alike.....and Weber kettle lids don't fit every drum tightly.....

 

[rickw]

Considering this,

The lid should fit as if it were on the Weber grill itself. Plus he was asking about the exaust part of the lid; it will be fine

Do either of you guys notice any issues with hot spots under the vents?

Can't say I've noticed. The outer portion of the grate runs around 40 degrees lower than the middle but as I have read that seems perfectly normal.

Are you having this issue Dave?

 

[rtom]

as Rickw said the grate is cooler toward the outside of the drum other than that I never really checked

Good discussion, thanks. My drum seems a little large in diameter. My Weber lid almost falls into the drum. With the Weber lid on, there is a 1/2 inch air gap on one side of the radius. The band I cut from the kettle fits very loosely inside the drum, right to the rolled edge. That is why I need to raise the band, and cannot just set it in.
I may be able to just stuff the rope and silicone, however I think it might fall or dislodge when I move the UDS in and out of the garage. That is why I would like to make it permanent.
I will post pics of my issues tomorrow, hopefully.
Again, my main concern is the exhaust issue with less holes.
Thanks

Oh ya, but don't worry about it, just a drum thing.

Original vent in Weber lid is fine.

I would listen to bubba with the 12 UDS's and counting I think that would make him the king

My Weber lid works just fine with its existing vent holes.....Then again my lid fits my drum top without any gaps.....Good Luck with your modification.
