My UDS build from a couple months ago has been on the back burner (busy at work & too lazy on Sunday to finish) but I did finally decide what to use as a charcoal basket.
A charcoal basket made by Dennis Linkletter (of the KomodoKamado company). He makes these charcoal baskets for his cookers and agreed to sell me two for my drum project. (thx Dennis)
the welding & fabrication is superb... couldn't be better. I'm going to tack on some feet so it stands off the bottom of the drum about 2 inches.
