Have some 45 records that have the small hole in the middle. Need to find the tool that makes the hole bigger so that it plays in my jukebox
I am aware of jukebox mechanisms that would clamp down on the record,
and if it detected a small-hole in the 7" disk, it would change the RPM
to 33 1/3, and the large hole would mean 45 RPM.
However, if we drill down into the history of the development of the 45,
we can see that it was developed as a replacement for the 10" 78 RPM
disk. It was also intended to be played on a distinct 45 RPM player,
and thus the large hole to discourage use on regular turntables.
Most of the 45s in the UK had a pushout centre (some round, some
triangular). 33s didn't have this. Ex-jukebox records had the pushout
pushed out, and clip-in new centres could be fitted
