I wouldn't waste my time on oil drums. They're thin steel, wood burner
flue gas is corrosive, and they just don't last that long. If I'm
going to make a stove, I use propane cylinders.

I hope you realise what you are saying is verging on criminal. But
more to the point dangerous. (The cylinder has to be burned or
something to render it safe as gas can be absorbed into the steel or
what did I hear about that.....)

There is quite a difference in the cubic capacities too, isn't there?
