Re: To those using rollers:
For attaching the PVC rollers on our prototype I lathed down a piece of Delrin round stock to .003 in larger in the diameter then the ID of the PVC (on my PVC this was 2.035 in) Then I drilled and tapped 1/4-20 center holes into the Delrin and pressed it into each side of the PVC. This gave me perfect point for axels. Also as tube guide Im going to pop rivet strips of treading. Its a bit expensive but for my application I really need the extra grip. You can see 254 use the method on the bottom roller of their 2006 design.

Good luck!

Anyone can watch Westcoast Choppers and see adults build things, but FIRST is great because it encourages kids to do the building and adults to do the watching.

GO DANVILLANS!!
