Shaping soft copper tubing into a tight coil?
I’m wanting to form 1/2″ OD soft copper tubing into a pretty tight coil, with the coil having approximately 3 1/2 ” outside diameter. I plan on using a piece of conduit of the appropriate size to wrap the tubing around to attain the coil diameter I want. I also have an appropriately sized coil spring tubing bender to help. Wondering if anyone has done this successfully before and/or have any suggestions to ensure I don’t collapse the tubing during the process.
This is how I do it. Use your tubing bender but fill the tubing with sand and plug or crimp the ends. Dont pack the tubing tight in fact leave about 2″ unfilled. When you start the coil keep the sand moving back and forth. Bend a little and shift the sand and bend a little more. It is time consuming but the sand keeps it from collapsing.
