looking to put a 60 degree sweep in a copper water pipe. any suggestions on how to bend without crimping the pipe?
Use a pipe or conduit bender. For something as thick a 7/8 you might want to anneal the rods at the bends, (heat and slow cool), with a torch before bending. You would also be well advised to drill any holes in the section to be bent AFTER you do the bending. It would be relatively easy to make a jig to hold the bent pieces together so the finished holes will all line up.
my first thought would be why? it may be possible to bend ridgid copper tubing but I've never seen it bent to that degree without kinking, even if it were to be heated cherry red, I doubt it would bend that far. soft copper will do what you want with alot less headache.
