Instead of sand I read about brown sugar used for bending. I tried it and it worked well. Hard to get it into the 1/4 OD tubing though. It took a really long time pounding it in with a 1/8 dia rod. But removal was easy, just soaked in warm water. Eric
Fair enough if you have spare tube to play with.
Nice idea!
I was using a home made rotary draw bender for the job I did and was bending the tubing to a fairly tight radius using a former I already had made for some solid bar. I found the solid nylon worked fine without any cuts and was fairly easy to remove when pre-lubricated. I think cutting it might make the bending a bit easier but might also lead to the nylon breaking on removal and making removing the remainder a bit of a pig. In my case I just grabbed the nylon bar in the vise and grabbed the bent copper tube and twisted and pulled and the nylon eased out of the bend.
2 inches is a problem for you?
