who has got their crank reground and used oversize bearings?

[Ben Davis]

I have two SR20 cranks with spun rod bearings. They are both a little
"scratchy" to the fingernail, one a bit more than the other. There are no
single, deep grooves around it- just general non-smoothness.

I've read the archives a bit and have yet to find someone who has actually
had this done and done successfully. I read of one person who had it ground
30 thousandths which is HUGE compared to the bearing tolerances in the area
of ten-thousandths that our motor takes. I would like to hear of some
success stories with getting this done before I would attempt it. It would
seem that since there are so few rod bearing sizes out there, normal and
oversize, that this operation would be very difficult. However, I find it
hard to swallow that since just one of my crank pins is scratchy to the
fingernail (smooth to the fingertip) that they are both garbage.
