Hi Nick
That will be the last resort, but I will if need be. I'm far to parsimonious to waste a good hub, and always consider that they must be very well lapped when they won't separate without a fight!
Last time I had this problem, I did eventually achieve separation of the hub (or taper) welding the puller over the mangled threads. The hubs are still in service on my ORT. I have been able to remove plenty of hubs since with the remains of the old puller, cut in half and welded to some gash steel to create a triangular ring that is clamped very tight at the rear of the thread allowing a 3 legged puller to be used. Having destroyed that with a hydraulic puller, I'll probably make another with the knackered puller I use to free this one up...
