I am thinking
I might make a fixture with some screws/pads to ba able to
move the platter slightly wrt the hub.
You?re quite right. The question amounts to the required accuracy for
such a fixture. From what you?re saying, it should be doable for an
amateur to make.
Another possible approach, if the platter diameter is consistent
within the runout tolerance, would be to make a fixture that?s simply
one large block of metal. Essentially the cone tip of the hub, and
That is 'large'. I think you'd need a lathe that could swing something
about 15" in diameter, which is a lot more than most enthusiasts have
over here. Quit apart from that fact that a block of metal that size
would not be exactly cheap.
My I wonder.... Suppose you had a basepalte witl a copy of the spindle
tip in the centre so as to locate the hub accurately. And 3 adjustable
mtal pds at a 7" or so radiau , spaced at 120 degress. Put the original
disk on, adjust the pads to just touch the otside edg. Then remove the
clamp ring, lift off the disk itself and remvoe the hub to wor on it.
Then put the reworked hub back on the 'spindle tip', slide the disk in
palce, the pads wil cetnre it, and fit the clampign ring.
Tasht should be quite easy to make...
