Nick,

The hole you have in your spindle would be fine, except you are using it in slightly the wrong way. By just sticking a 3/16" bar in the hole, it will just bend as the bar is working in tension. But stick a 3/16" bar in the hole in shear, then you have a very strong piece of metal. What I am on about is a C spanner with a 3/16" pin, or something to that effect.

I have done a C-o-C to explain.

Bogs,

Thanks for taking the time to do that, I should have thought of this being a mechanical engineer! I now think this is the method that'll work as long as I can make something that will support it nice and solid pushing off the metal stand probably.

Cheers,

Nick

Hi,

Good news, I've got the chuck off the spindle. I had to resort to  :hammer: but I should have tried this earlier and it would have saved me a change wheel!  :doh:  :bang:

When I originally tried locking it up by putting in lowest back gear, I tried to remove the chuck by wedging a jack handle (big lever) in the chuck jaws and leaning on it. This just turned the gears over so that's when I thought I was at a loss and started wedging things in the, unbeknown to me, soft change gears and broke one!

I was just making a brew before and staring out of the window at which point I decided to go into the garage and give have another quick bash at it (literally)! I put it in the lowest back gear but this time wedged a 10" or so length of what i think is chisel steel (I have a few bits of octaganol steel, I can only assume they are for chisels? ) in the chuck and hit it with the hammer! The small hammer just bounced off but it didn't turn the gears over. So with my heart in my mouth I got the sledge hammer and gave it a few 'taps' with that with the slack taken up and it surrendered!  :D Just wish I'd done that in the first place  :scratch:  ::)

Anyway, it's off so I suppose I can get on with turning the register on the back plate to fit the new chuck. Need to go and get that new change wheel too and probably turn up some bush for that.

Cheers for all your help and ideas on this one guys.

Nick
