Pro-ject 1.2 turntable has ground to a halt

I have an approximately 10 year old Pro-Ject 1.2 turntable. Over the
last year, the big heavy platter has begun scraping as it spins, and
has finally ground to a halt. If I elevate the platter, by putting a
shim (two old CDs) between it and the sub-platter, that elevates it
enough that it spins again, but with lots of wobble. Obviously not an
ideal fix.
I don't know what's happening, but I'm guessing the sub-platter (which
is what actually spins, driven by the motor/belts) has descended/sunk
a bit.
Has anyone experienced anything similar with this turntable? Is there
any way to fix this problem?
Thanks in advance!
Sounds to me like you need to take some measurements and see where the
clearance issues actually lie. I don't know the Pro*ject table in question,
and my suggestions are general for turntables that have the platter assembly
suspended on springs. If the turntable platter/sub-chassis has a suspension
then I suspect that the suspension has sagged. In some tables, it's possible
to adjust screws inside the springs that the platter/sub-chassis sits on to
raise of lower the assembly. So it might yield to adjustment. If you can
raise (or lower depending on the design) the sub-chassis as it sits on its
springs, be careful to use a level on the PLATTER to make sure that you
adjust all the suspension springs exactly the same amount. Turntables need to
remain level.
Other than that, I suggest that you contact Sumiko, the importer/distributor
(if you're in the USA) in Berkeley Ca. and talk to one of their technicians.
