the piece I was looking for is part number 156136 (or alternate 157054) in
the TRF TR6 book. I broke the washer that was in there, so I bought a new
one from Moss. The finish of the new piece was fairly rough, some sort of
greyish finish. Removing the grey finish so I have a uniform shiney finish
seems to have done the trick. The resulting part is (by micrometer
measurement) still good (less than .001" variation measured at several
places. I think I still have a precision washer.
Regarding the spacer washers 129941 through 129944, given the dimensions
that I had, the smallest (129941) was .003 too big!
It looks like the polishing actually worked. I'll mic it to be sure the
washer faces are still parallel.
I did find it interesting that TRF doesn't list the 156136 or 157054 as
available anymore.
I think the grey "stuff" is some sort of leftover from the hardening
process. But there's a LOT of it. About .005". WOW.
