RE: Aluminum Hull? Aluminum Brazing?
A friend of mine is a welder and is building a springer tug from aluminum he tiged the 1/8 bottom and is using alcor flux core solder made by harris co. and sold by praxair welding supply on the thinner metal. It works very well and flows good even with propane. metal needs to be very clean. If you want any more info I can hook you up with him. good luck hope this helps. mike
