Thread: Bending copper tubing, Help Needed!

Tweet

I found this
Cal-Van Tools Heavy Duty Multiple Size Tubing Bender - Model 758 at Sears.com

That copper bending spring looks pretty cool. I was thinking you might be able to insert some smaller diameter plastic tubing inside the copper to fill in the inside and assist in bending without crimping, but this simple spring looks great. And cheap too. I think if I were going to make a mad scientist room, the tool would come in handy to shape metal coils for lab equipment. Gee you never know what you will learn by reading these posts. Thanks so much everyone.

I've always heard filling the tube with sand (or rice if larger diameter) and then bending it. The fill inside keeps the sides from collapsing. Makes sense - but I've never tried it (never had the need to bend any tubing )
