Live Axle how to

[EricH]

You guys are from Chandler, AZ... I would suggest a weekend road trip to Kingman, AZ. FRC 60 is one of the originators of the West Coast Drive. That was 7 years ago.

For a few answers: The hex axle is more common, but not for the reason you say. It's for reduction of stress when transferring power. You can use a round shaft, but you'll need some form of keyway; keyways like to act as stress concentrators. That can be pretty bad for the axle, maybe not immediately, and maybe not if your axle is properly sized, but potentially after an event, or during one, say during finals matches...

The Kitbot has 2 bearings per wheel, IIRC. If you only have one, there can be a bit of a problem. Typically, bearings are pressed in.

Hardware: clips on the end of the shaft, setscrews, it varies by design.
