bending/rolling soft copper tubing

[davey]

Any thoughts on bending or rolling 3/4 inch soft copper tubing? I tried to find a tubing bender but the only ones I could find were very expensive. I'm trying to do the coil around the smoke stack pre-heater and a buddy gave me a roll of tubing to use.

Try to borrow an electrical EMT bender. They support the sides and top of the tubing so it won’t kink.

davey; We rapped 3/4 around the stack pipe on a small D&G rig we had a couple of years ago and we filled the tubing with sand and capped the ends. Then made small bends and it worked for us.

Try to find a spring that fits good inside the pipe and bend a little at a time

I have been thinking about the same thing. I think if I do it, I might find something that is of slightly larger dia than my stack and bend around that. then I will slide the whole thing down over my stack..I dont particularly want the coil touching the stack, it will get hot enough without actually being in contact with it.

Deff use a spring bender. My grandfather had several know idea where he got them as he's long gone. Here is a pic
