Live Axle how to

[daniel_dsouza]

Hello everyone,
Our team has always used the kitbot drivetrain, and therfore has no experience with live axles on a drivetrain. I want to try and CAD a design to present to my team leaders, who have expressed a desire to change from the kitbot drivetrain. However, I can't figure out what parts to use...

I have heard that a hex axle is usually better than a rounded one, mainly due to the complexity of securing something to a round shaft. However, I can't figure out what parts I absolutely need or where to get them. (besides AndyMark)

Is far as I know, the kitbot had only one bearing to a wheel, and that was just pressed in. How should I attach bearings to the structural part of the drivetrain?*

What hardware should I used to attach wheels and sprokets to an axle?*

If our team decides to use a version of the design for the season, then will posting it on CD count as "open sourcing" it?

What are your opinions about direct drive for the center wheel (6wd) vs. linking it with a chain?

Is there anythign you wish you had known before making a live axle drive system?

*pictures would also be apreciated

Thanks in advance for answering a rookie's questions.
