Many thanks to the people on this forum, with your help I build my own USD smoker. Got a drum from a home builder across the street, they only used it to store trash in. Burned it out, and put 2 nipples and a valve in it. Had to cut the top ring off to fit my old webber lid and put the grate in. Cooked a few small things in it to see how it holds up, and now it's time for my first brisket!

I had to cut the top ring off the barret to make it fit my webber lid:
And my first 12lbs brisket, going for a 18 hour smoke hopefully:
