Chris...must pass on the set for experimenting...tks anyway.
Andrew...had not thought of the wiper action....I was going by the grooves in a set of Clevite bearings we used to use in drag engines (and some circle track ones) they had a pattern to the grooves that looked like the viens in a tree leaf...a central radial groove with smaller ones radiating out in a diagonal pattern.
I just realised the those were for a rotating bearing...whereas the rockers do not rotate...they just move a slight bit in comparison.
Oh well.
