Read the entire thread.
Before I read the thread, I made this out of a metal 5 gal pail I had. Didn't have nearly the airflow for a complete even burn.
Also (before I read the thread) was going to try cutting this old compressor - 16" diameter tank for a coal basket with stable feet. Now might just cut it in 1/2, put a grate on it to have a place to set a hot chimney starter.
Go with an expanded metal surround.
And again, (BIRTT) - Got this free barrel that had corn sweetener / red lining.Thought it was a great score. Full day of burn. Bunch of grinding, sanding. Still too much liner left.
Wiped with denatured alcohol, gave another burn, then some more wire wheel.
Finally looked good.
As repeated often, get used one without a lining, or a new unlined one. Save yourself some of dirty work. Get to cooking faster.
Got some Kingsford for the test, and I have a few places by me that stock the Wicked Good lump and briqs, will get some for the first cook soon. Can't wait.
