stainless motorcycle brake rotors

[mattinspokane]

has anyone tried to "drill" stainless brake rotors on the plasma table? I am worried thay might warp with the heat. i am building a cb750 cafe racer and would like to do some design details in the brake rotors. before i ruin any parts, has anyone gone down this road already? thoughts and input appreciated.

It seems more dangerous than practical to me. I wouldn't do it...
