New Cage Builder Question

[bllabong89]

So, I am putting my fabricating skills to the test and will try to make my own cage. I don't think it should be too challenging but I do have a couple questions.

First is what kind of tubing should I use? I have heard 2"x.090 DOM Tubing and I read the Formula D regulations and they say 2"x.095 DOM plus/minus .01 I believe. I will most likely not be using this car in any Formula D events but I would like to have what is right for the sport.

Second is I have a 16 ton Tubing bender with a pneumatic pedal to bend my tubes. Will DOM tubing bend with this bender and not kink? It is similar to the bender Eugene used on his s13 build on Zilvia.


Last question is does anyone know of a good tubing notcher?

Thanks everyone for looking.
