Here is the thread where I got the ideas to build an UDS (Ugly Drum Smoker)

I did not put any valves on it. All I did was drill three holes on the bottom for vents and used three magnets to cover up the holes and control heat.
I had an old weber kettle top cover which I had to bend and open up the edges for it to fit on my drum.
It works great and is super low tech which is the way I like it.
This was the first cook that I did on this smoker years ago.
