I needed 3 mills or a bit more, and that stuff is 2 mills thick. So there is some preload on those 2 bearings, and it seems to have worked well for several years now. But this time I believe I'll make a die stamp and cut them out with a 4lb hammer against a block of something like cherry or HDPE. Scissors and pocket knives just don't do it, it rips too easy. Got to be a better way. Thanks Jon. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
