Tube Bender - Die Size

[Camaro Zach]

I have the JD2 Model 3 and have the 1 5/8" round tube die. Soon ill be getting a 1", and 1 1/4" round for control arms. And ill be making my own 1/2",3/4", and 1" sq. tube dies.
Really it depends on what your sanction body requires. Quite a few people use 1 1/2" for crossmembers and such (to me the 1 5/8" is close enough) and some sanction bodies require 1 3/4" material.



but the most common ones i'd say are 1", 1 1/2", 1 5/8",and 1 3/4" round dies

I also have a model 3 bender and I love it. The 1 5\8 die on a 5.5 is very usefull.
