Building fire ring

Ok so i must be a moron, i cant find a search tab anywhere on the site. I am a member of a lot of forums so i know about annoying it is to have people post questiont that have been asked a hundred times.

That said... Can you guys help me with some ideas for a fire ring/charcoal basket in my UDS. I do not have the equipment to weld or cut sheet metal so it has to be a job i can put together.

I found 12x24" sheets of expanded steel at home depot for 10 bucks each but i think i would need 2. Does it need to be 12" high?

Would a 10" steel pot with a bazillion holes drilled in it work well?

I don't own nor have I ever used a WSM, but I do use the ring of fire method on my 22.5" OTG all the time to BBQ. With that method, I can maintain temps of ~220 for 10+ hours with no water pan. All I do is circle (with a gap) the charcoal grate with KB briquettes 2 wide and 2 high placing maybe 3-4 wood chunks along the path (including at the start). I start the ring with 4 lit coals. I leave the top vent open all the way, and leave the bottom vent open until it gets close to temp and then close it it 1/8th open.

I don't have any experience with the WSM, but I could imagine that doing something similar would probably give you at least any equally long (if not longer) burn with stead temps given how much more efficient on fuel I imagine the WSM is when compared to an OTG.

EDIT: Okay, I just realized you were asking about building a charcoal basket, not asking about the "ring of fire" method. Please ignore my post! Doh!

I may not be the first person to post this, but I found this and it looks like it would work.

I would have to put legs on it... But it may save me some trouble.
