Same here, just sheet metal, plate and castings. I was taught to put some pure acet soot over it, and when that burns off you are pretty close to welding temp. Not pretty, but oxy/acet welding of aluminium was common before fancy welding equipment became readily available. I have a Henrob too, I have stuck 2 Coke cans together to try and duplicate the demos I saw, but haven't tried it on any alloy....maybe I should give it a go.
