It's a threaded square taper, and I've gone through all of the normal steps, it's been steeped in penetrating oil for a week, I'm turning towards the front, I have a 5ft "persuader" bar on the end of a spanner with heat and although I got the drive side to turn (almost one full rotation) it was at the cost of the teeth so now there's nothing for the tool to grab.
I thought once it turned at all it would release up but no so I'm guessing there's a lot of internal thread damage anyway.
I don't have access to a pillar drill so I can't go that route.
LBS has already waved the white flag.
The frame is an M2 Stumpy and holds a great deal of sentimental value so it is fairly daunting to take the step of bracing the frame on it's side and belting it with a sledgehammer. If anyone has any magic solutions that don't involve welding (fabricator looked and is pushing the sledge hammer route) I would be very grateful.
