Heres a thought, wind a soft wire helix (i.e. spring) that can be slid into the pipe. Bend the pipe then pull on the end of the helix which will collapse and enable it to be pulled free of the tightest bends. |

John H, You can buy sets of small bending springs, unfortunately, if you do too sharp a radius (and not all that small either), you have to destroy them to get them out. After buying two sets, I came to the conclusion that they really are a waste of time and money, I could bend tubes better just by using my fingers. My way John (S), would be to bend a solid bar first to whatever radius you require, then bend a twist drill in it's middle to the same radius. Using the bent drill, drill down thru the bent bar to make the bent tube. It's easy when you know how :lol: John |

We can still get curtain spring which I have used with thin wall aluminium tubing. I wish I could get something for the 36mm thin wall steel tubing I used on my bike project, but I had a kludge that was better than expected, I hacksawed partial crosswise cuts until the tubing would easily bend into the required curve then brushed flux into the cuts and brazed them. I guess that wont be 100% strength but it certainly feels quite sturdy. |
