By the way I can see a (brand-new) #2 live center move in thea
perfect fit, and need to clean up the tailstock via a reamer.
The rotating center (slang is live-center) is absolutly fixed on
axis. As far as the work goes, it would not see any difference
between a solid and rotation center.
The ball bearings are not there to allow for any mis-alignment.
You really need to get the tailstock aligned properly.
As for the hand reamer, it should work.
A #2, MT finishing reamer would cost about $30.00 from a supplier. I
had bought one a few years ago and offered to pass it around the
7x10minilathe group, but it got lost and never made it home.
I too would like to use one to clean up a tailstock.
Depending on the part, I might make a holder-wrench for the tailstock
sleeve, chuck the reamer in the 3-jaw and slide the sleeve over the
reamer. Then use the carriage to put some feed pressure on it and
rotate the spindle by hand.
