How Do I Pressure Test a Tank?

[AlRice]

I'm just about finished welding my smoke tank and want to pressure test it. Does anyone have an idea for an inlet valve/ and gage setup? I was thinking of brazing an old schrader valve from a tire to a brass "T", screwing a low pressure gauge into the other side of the tee, then screwing the whole assembly into one of the 1/4" or 1/8" npt bungs on the tank. Is there a simpler way?
Thanks,
Al
