Hi Lads thanks for the ideas so far. I have had a large air impact gun onto the end of a bit of say 30mm hex bar in the chuck with the socket bottomed out on the hex bar and kept repeating say 30 secs of impacting then tried again ...and again .........and again, it was really vibrating through the whole area and also pressing onto it at the same time, still totally solid.
Bob the chuck was definatly screwed right up but only with hand pressure, they were both the same temp too.
I am glad to hear about the rifle barrels as at least the princable should work.
Another suggestion on Madmodders has been to make a taper gadget that would fit into the rear end of the spindle tube then expand by way of a bolt type set up , then have a long lever on this to stop the spindle rotating, so it would be , in effect then just be a tube with a lever on the rear end and a backplate threaded on the other so any forces involved with trying to remove it would not involve the gears. Seems like a good idea but to be honest with the force I have had on it up to now I can not see a taper wedge type gadget not rotating in the spindle.
The other thing is why has it happened and how do I stop it happening again ?
As a note the much larger chuck on my Binns and Berry lathe of the same design that has not been took off for maybe 10 years, with a bit hex and a 12 inch spanner and only hand jerk came loose no bother
......... its a funny old world eh .
Cheers Mick
