Hi lads, thanks for theadvice and support, I am glad to report ..............
The Ba##### is off after my mate Dave and myself had more tries we have then made a special parting tool and went with the plan of parting a slit in the back plate just a fraction where it mates with the shoulder of the spindle. The reason being it might work and the back plate might be able to be used again as enough metal there or if not it would be easier to turn it off in the threaded area with this tool rather than turning the whole six inch plate away.
Photos will follow but once almost through but before risking hitting the spindle , it came off with hand pressure on an adjustable spanner.
What I found ( and had seen befoe once I saw it to remind myself ) was a fault in the threads of the backplate, its got a blow whole in the casting and the threads run through this fault leaving sharp edges that must be the cause I presume.
Anyway its off and the spindle is ok so I just need to make or find a backplate now but have the four jaw chuck until then.
For anyone else with the same problem as I think it was Pete W said with the rifle barrels this method does work so well worth noting .
Cheers Mick
