The nominal ID of a 9/16 washer is 0.594 which gives you about 0.015"
clearance which should be about right. Gordon's right you will need to grind
a flat on one side to fit. I like idea of using Nylon or Delrin; but the
long term service temperature of these materials is fairly low (~200F) so
I'm not sure how they would do in hot oil. Maybe a cut down brass washer?
