I recently acquired an Edison Home cylinder player, 2/4 minute, that has a Blue Amberola cylinder stuck (I mean SERIOUSLY stuck) on the mandrel. It is not a cylinder I want to save, as apparently a previous owner tried to play it on 2 minute setting with a C reproducer. Let it get through about half the cylinder before figuring out it wouldn't work like that. Or maybe something worse - at any rate, it won't be playing again. Anyway, I want to get it off without damaging the mandrel or any other part of the machine. I'd rather not go at it with a hammer and chisel. Any advice or suggestions?

I am surprised that a 2 minute sapphire would do any significant damage to a BA, which was designed for a heavier reproducer and a diamond stylus. Usually it is the other way round: people trying to play a wax cylinder with a Diamond reproducer.
Anyway, you can probably remove the cylinder from the mandrel by taking a wooden dowel, holding it against the left edge of the cylinder, and gently tapping it with a hammer, rotating the cylinder as you go. After a while, with patience, it should work loose. As a boost, you might try some penetrating oil where the plaster core meets the mandrel.
Should all else fail, perhaps you could cut the celluloid off with a utility knife - say, two cuts along its length on either side - and break the plaster off the mandrel.
Mind you, I have never faced this situation; but I offer these suggestions anyway.
(BTW: is your Home an earlier model with a combination attachment and an endgate, or a later model without the endgate?)
