It has happened a couple of times now in 6 months.
3 jaw chuck got very very tight on the mandrel and I couldn't dismount it from the lathe. After using flycutter to cut a spur gear ( I made a hopeless mess of it but learned heaps)
Eventually I gave the chuck key a tap with a rubber hammer. And yes I know I shouldn't but it did the trick.
Any tricks I can try ? ie put a paper or rubber washer between the chuck and the register ?
Keep it clean and tidy with no swarf where it shouldnt be, extra bit of oil / grease / wax / other ?
............. and google found this for me http://ift.tt/1jVdkOl so I wont use a hammer next time - as that chap says its interrupted cuts that really jam it tight.
.... does everybody accept that an interrupted cut can really tighten the chuck onto the lathe and simply deal with it when it happens.
