hey people, just a quick question: is 4mm mild steel strong enough to mount a wheelchair motor?
what i am planning to do is to have an L shaped bit of steel which i could bolt the gearbox end of it to and then atach that to a long bit of 10 or 12mm HDPE with some motorbike exaust mounts.

would this hold up to combat? by the way the wheels and motors are inside the robot
thanks
