Thanks a lot for answering these questions; very very helpful.

We do use 5052 for its ability to bend.
I do not believe that the laser and the turrent punch have the same tolerances. The laser can hit holes within .001 and I believe that the turret pouch will get within ~.005, and Travis and or Austin can correct if I am wrong. We will usually spec out holes on transmissions and whatnot that need to be within laser tolerance and we try to make everything else "punchable".
As for bending near holes, you can deform the hole when it is located near a bend, but in a somewhat predictable way. For holes that don't require major accuracy like our
tensioner allen key clearance holes, we are okay placing them near bends, but we try to avoid it when possible. You can also see in the siderail of our
drivetrain we put a hole on the inside flange where the transmission goes. While we don't like breaking up the flange, the hole is necessary for our second reduction from out transmission.
slots tend not to deform much when the bend is in the middle of the slot. There have been a few side projects where we do some interesting things with this, but I cannot find any pictures right now...
Hope I have answered your questions
