Re: Wheel Axle Material
We have been using 1018 carbon steel 1/2" hex for our shafts for 3-4 years now. It's half the price of the 4140 and is more than adequete for FRC use. We generally don't want to worry about axles failing and take the weight penalty of the steel down low where it helps the CG.
In our pre-2009 drivetrains that had dead axles we just used grade 8 3/8" shoulder bolts because it was an easy way to assemble them.
