I've only had one stuck like that. What ended up working for me was to lock a long bar (3-4 feet) sideways in the chuck jaws and hang a bucket of junk from the end. Next morning the bucket was on the ground, the chuck came loose. Voodoo magic, dunno. Someone before me had beat on it good and broke some gear teeth, chuck handle was hammered. Bubba had gotten to it. The lathe was next to a dumpster when I found it.
John Oder on Practical Machinist showed how he made a large wrench for the outboard end and one for the chuck, squeezed like scissors to get it off. Plumbers will use a similar technique with pipe wrenches to get stuck fittings loose.
How your chuck got stuck is a mystery. Is the rear face perfectly square to the threads? Perhaps a little cockeyed and it wedged tight? Still a puzzle though. A jokester with some loctite?
Nice looking lathe. Wipe your tears away and keep at it. How frustrating. Might have to turn the backplate into chips, but I'd be keen on finding out why it got stuck...
