Any clues as to when those sales are?

I haven't had a problem with getting the psa to stick to my disks.  I did
take the disks to a machine shop and had them re-bore the arbor hole.
While I was at it, I had the machinist make an arbor to fit the disk so
that there is very little play on the arbor.  I still make sure the disk
is true before sanding anything.
