CD spindle too big to deal with CD hole size variations? Well I think this unlikely as there were comparatively few manufacturers of CD transports ( of which the spindle is an intrinsic part). Therefore if one of the manufacturers made even slightly oversized spindles they would have appeared in thousands of players and be a common problem. As it is in the 34 years since the introduction of CD this is the first reported case of it that I have come across.

Your profile lists two players , a Wadia 830 and an Arcam Alpha 9, both of which are now some years out of production and both of which used transports manufactured by the many thousand. So have you been suffering with this fault for years as both machines must have been in use for a long time but have only just decided to rectify it ? Incidentally the Pioneer transport in the Wadia is well known to me as I owned a player equipped with one for years and never had any problems. The transport in the Arcam is a Sony and as they were one of CD's patent holders one can be pretty sure that their spindles were not out of specification. BTW, spindles are also normally slightly chamferred in profile to account for size variation.

You say it affects only " some" discs. What are they? Do they come from a particular label or CD manufacturing plant? The size of the hole on CDs and its tolerances are set out in the redbook standard and I haven't heard of plants manufacturing outside of these. I have well over 2000 CDs and have used many CD players and transports over the years. Never any problem with this issue.

Perhaps some further information from you may help inmates work out what the real problem may be. I hope that you can understand my doubt in regard to out of tolerance hole or spindle size.

You're in luck. A reamer tool comes in that size. Nt - geoffkait 14:59:18 05/05/17 (4)

It's actually the roundness that's out of spec. At least the spindle holes are centered. - geoffkait 04:08:11 05/07/17 (0)
