Wow, thats a cool idea! Did you have much of an improvement in weight reduction? Any problems with warping? Unexpected benefits? Detriments? Why did you stop using HDPE in your machines?

I remember making our 2006 robot's auto-retracking guides (in case the robot tried to throw a track) out of UHMW and had a heck of a time doing it... i think i spent more time whittling with an exacto knife than actually machining the parts.

Very interesting...
