Anyone know a good way to make a small centrehole into a big one?
I'm talking ofcourse about the ones with no possibility to pop out the centre.

A reamer is the best bet. You could even start off with the careful application of a countersinking drill bit. Care is obviously the watchword...because you want the hole in the middle !

There's usually at least a ridge or step of some kind to indicate the area of the "jukebox" hole.
Very many records are pressed with slightly off centre holes...so don't get too paranoid about it. The main thing is be sure that you don't damage the playing surface with the debris or any tool you choose to use.

have you tried this?

Yes, many years ago now. A mate of mine acquired a Juke Box and wanted to load a number of singles without the partially cut large spindle hole.

It's one of those jobs where the tool is perhaps not the most imnportant thing. It's 90% care and attention...and shouldn't be attempted by the habitually "ham fisted" ;^)

thanks for advice! Guess I'll test it on a terrible record first and then move on to the keepers

Why would you want to do it ?

My jukebox slows all records with small holes down to 33RPM,
which kinda makes them useless.
