I think the only time you'd do this -- EVER -- would be if you cannot dial
your tonearm heavy enough
to track a very badly warped record. And I think you'd be better off
investing in a couple of plates
of 13"x13" glass and putting the record in an oven on the WARM setting and
no higher for an hour or
two and then turning the oven off and letting it cool to room temp. The
top plate of glass should be
heavier than the bottom plate, so gravity can be your ally. I'd much
rather take measures on the
vinyl than on the cartridge and tonearm.
While that method works just fine for shellac discs (78's), I tend to
wonder how well it would work on vinyl records. With vinyl, the warpage
as actually caused by expansion, and not by the substance becoming more
flexible as its temperature rises...
