Re: Polyethylene Washers ?????
Gary:
If you access to a lathe somewhere just chuck up some solid PE rod stock and
drill a hole in it. Then cut off the washers with the cutoff tool.
Sometimes a local school or tech college would let you use their lathe if
you can convince the shop manager your project is a worthwhile endeavor.
Happy Holidays,
