Thanks! I haven't started yet, but I would certainly clean the surfaces. Unfortunately, there are no brass to brass joints, only white metal or aluminum to brass. Strength is definitely important.
Thanks! I've had much better luck gluing metal with epoxy, but it would probably make for a more difficult assembly. I would have to take the parts out of the jig, apply glue, and put them back in. It would be great to jig everything up, hit the joints with CA, and pull out a finished chassis. However, if it just falls apart, not so great.
