Having
established that the Technics motor requires very accurate alignment of
the parts I started with the spindle assembly. I took an old Technics
bearing and cut off the bottom section. The bush bearing was knocked
out of the top part with a drift. The bush measures O.D. 12mm and I.D. 8mm so the
10mm ProJect spindle wouldn't fit. I just happened to have a couple of
meters of Aluminium extrusion lying around that was O.D. 12mm and I.D.
10mm,
perfect. I cut a small piece from this and pressed it fully into the
housing in a vice, it was a tight fit. The ProJect spindle was a close
sliding fit on the inside diameter, I couldn't have asked for a better
combination. The Technics boss could now be centred exactly on the new
spindle/base.
