I have an 8529. It has a shaft lock and comes with an offset wrench. I've
heard this bit about the rubber piece before. You will be disappointed. The
PC collets are a rather snug fit. The force needed to push it into the
cullet will compress the rubber. No way to tell how much but will be
different each time you change bits. Best you can hope for is close. If you
put something solid like a piece of steel under it, the collet will never
close right and you run the risk of the bit coming loose though the bit will
go in at the same height every time. Now that I think about it, a block of
about 90 durometer urethane would probably work. Height variations would
probably be no more than about .005.

I went to WWS last month and really learned few things. One was with a
router table, put a rubber piece inside the collet so that I can switch
back and forth with (CMT) router bits and it will remain same height
(for cabinetmaking). So I went to ACE and bought some faucet pieces.
Drop one in the collet, still too deep. Anyone know about this? Before I
call PC, does anyone have a solution for this? a deep rubber piece? What?

One thing I am thinking is that since PC has been around for long time,
shouldn't they, by now, see a "need" for a collet lock (and a better
offset wench)? I got PC 7518.
