Scott,
I have some plastic rod, it is supposed to be UHMW.
UHMW is supposed to be good for bearings.

I have good luck using:
Sfpm, can be just about anything, up to 500.
Tools, SHARP with high back and side rake, in excess of 15 degrees,
diamond honed sharp, moderate radius.
Feed, high feed rates.
Coolant, none.
Drilling, high feed rate.
Accuracy, should be able to hold a few mills, but some have reported
changes after machining.
Chips, lathe chips will be stringy and stretchy, tangling in the
chuck, and grabbing. Thin strings will wrap around the part,
sometimes requiring removal.
Heat, not a problem, as long as high feed rates are used.

Use high speed steel, Dave didn't say it, only implyed.
