      Hi all

      I want to polish a BG4000 platter – that’s the heavy one, with the stroboscope markings on the underside. I can’t figure out how to SEPARATE the lightweight shiny top portion, from the heavy dull bottom portion, in order to remove the plastic ribs.

      BTW – This BG4000 platter is the identical platter found on the Early BG4002 models with the AC motor.

      Has anyone done this, or knows HOW to do this?

      Thanks

        I would not try as the two pieces are bonded. Applying heat to relax the bond would damage the ribs.

          Mark thanks

          But my question is How to DO it, not “How NOT to do it”.

          Obviously Direct heat would damage the plastic ribs.

          Mentioned here that a platter arrived separated after heavy handling in transit.

          So, it IS possible to separate them, but that method I would not try.

          Perhaps a pot of boiling water, and soaking the platter inside?

            Based upon Beolover’s sample, that separation was caused by force. Note that there is thin film residue to the old bond indicating that a shear force will likely be more successful than heat softening. This would call for a non-marring mallet with the platter supported thru the center hole. You could also try a .1mm stainless steel spudger to work around the edge to break the bond.
