Are These Delrin Washers?

Thank you Tony!

I go some quick information on that stuff:

A fine weave cotton fabric base phenolic laminate which provides a finer surface texture and better machinability than Grade CE. Grade LE is low in moisture pick-up and dissipation factor, and is excellent in all electrical properties. It can be machined easily and cleanly to very close tolerances, and is recommended for use where there is need for good mechanical properties combined with excellent electrical characteristics.
Graphite is added as a solid lubrication.

This stuff sounds good, but Delrin might be a better choice.

They sure are slick...from the side look like a phenolic type material.

I have a hunch those glass fibers I mentioned might be carbon fiber.

Just call me Matlock...hee hee!
