Hello:
I want to make a new truss structure using thin wall aluminum tubing, to save weight. The tube is only 4' long so it doesn't need to come apart. Since the aluminum tubing is so thin, I am thinking of using epoxy to bond the aluminum parts together instead of welding. I have used epoxy for smaller parts, such as for some parts that hold my spider, but not for the whole structure.
I bought some J-B weld since I read is was quite good for bonding metal. Does anyone have experience using this stuff? Are there other epoxies that are recommended for aluminum? What is the optimal thickness of the bond? Or, is it just plain stupid to try and epoxy a telescope together?
Cheers
