Its feels like both inner and outer races are touching each other when assembled in the direction they were installed. Both bearings are installed into the block from the nut end, with nothing between either set of races ATM. I could turn them around though, which would mean that spacing the outers would achieve the same effect, and that would then allow the nut to adjust the preload. In that event, even a 20 thou thick spacer would be fine. If it wasn't for the thin face on the outers when assembled that way, its only about .55mm wide on that side. But it should work. So, put one bearing in with the thicker outer edge facing left, a dab of grease to hold a formed piece of 30 gage kynar wire stripped, laid in the grease and push the 2nd bearing in to trap the angular and the nut, which has a set-screw for locking, brought up to put some pressure on the inners, sound like that would work just fine. That wire wire is too thick, but it will cold flow some, so if the nut is snugged up, eventually it should be able for the wire to support the loading for a long time. Sounds like a winner to me Andy, thanks. I'll check in later when I've tried it. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
