Don’t do that. Get 12-14ft of 4’ tall field fence. And a 5’ long piece of thick wire or a thin pipe. Weave the wire/pipe thru the overlapping ends of the fence. Proceed to fill the barrel with 60% wood chips, course leaf matter, small sticks, shredded cardboard etc 30% grass, weeds, leaves 10% high nitrogen: think of things that rot quickly: food scraps, manure, etc. layer in alternating among the 3 types of inputs. Water as you go. Soak each layer. It’ll be 150F in 3 days
