I hand reamed with the 0.250 then the 0.2507. Makes a HUGE difference. I tried it on 3 of them - 2 are so tightly matched to the spindle, I may not need set screws. in any case I taped the set screw holes with an m3 tap - close enough to the actual required hole. I've never taped plastic before - soooo much easier than metal.
If any of the plastic ones work, I'll just leave the 316Ls alone.
