Re: Working with copper
I'm still wondering if the heat from the engine exhaust will turn the silver solder molten. It did mine and in pretty short order. I was using expensive silver solder with the appropriate flus made for it. It soldered the copper fittings together beautifully. The problem was too much heat from the exhaust manifold once I rode the bike. And that was just a HF 79cc Greyhound engine.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
