    I an looking at modifying a frame to build a BTR type frame. The tube is 1" OD .058 wall. I am thinking of a 7" radius. To purchase a manderal would be to expensive for a onetime use. I never had much luch with the sand fill method. I would be greatful for any ideas.

    What is the final angle of the piece of pipe going to be , assuming the 7inch radius is at the bend point??..I figure you are using round not square tubing...will you be bending a piece of tubing you have cut off the original bike ??

    Bending 1" OD tubing

    I just measured an old cast iron 3/4" EMT bender. It starts out a 1.030" and ends up at 0.960. It is to big to fit in my lathe so I will attempt to take a file to it to open it up to 1.020.

    If so I can bend the tubing using it the way the tool was designed or perhaps build a backer and use it in a manderal type setup.
