Very simple solution (from the guy who suggested Windex)..if you have an extra
turntable mat and a junk LP (preferably an early 50s pressing, without the
raised edges and center), that will raise the disc enough to fit over the top
of the spindle. I do this all the time to center records. And I say nasty
things to people who advocate drilling larger center holes.

But I've never run across an entire collection of discs, instantaneous or
otherwise, whose center holes were all too small for a standard turntable
