Slightly at a tangent to Model Engineering but worth a try.
I need a hot air gun to shrink some 'heat shrink' onto some cables. No power available. Not feasible to use a genny. I thought of adapting a gas blowtorch to provide heat at the nozzle instead of a flame. I have a choice of 3 types of blowtorch. Plumbers gas bottle type with a hose and torch Plumbers disposable gas can type DIY 'ronson type' " " "
Problem is I do not know the best way of doing it.
Cables are quite hefty 400mm^2 each core!! but I want to keep away from direct heat.
All advice gratefully received, thanks
