My neighbors think I'm crazy!! But she's already a beauty!
It is hard to find drums in Germany, at least close by. Most have sealed tops and have oil in them or are too expensive.
I lucked out and found 2 drums with lids, got both for $30. Both had orange syrup in them and liners.
I decided to go with 3 intake vents. 3/4 ball valves
U.S size nuts are nearly impossible to find, so a friend welded the threads to the drum.
Sheets of expanded metal are very expensive. Smaller pieces can be bought at most "Home Depot" style stores.
Welded to an old pizza pan
I'm thinking a vent similiar to Weber kettle lid.
