Micro Seiki RX 5000

This is quite old but I just acquired one from an old customer who passed away. I'm posting in case, like me, anyone else new has the issue and there is some misinformation here.  You do insert two screws into the holes on the platter.  They are M3 and you should be able to do it with 4" or longer.  You can fashion handles or use vise grips to pull them up.  When they screw all the way down they hit the steel plinth - there's nothing there to damage.  Mine would lift about 1/8" and then stop.  I worked three wooden shims around the edges and with a friend would slowly work them in as we pulled up.  This applied even pressure.  At about another 1'8" up it released.  The spindle remains in the bearing shaft in the table.  It is sealed and basically inaccessible.  Mine is in great shape and sounds terrific.  

If the OP has been tugging on his platter for the 14 years since he posted, he ought to be quite muscular by now or else ridden with stress fractures.
