Hi

I have recently brought a second hand Clarke CL500M lathe/mill. The mill
head has a milling chuck that takes collets and I'd like to be able fit a
standard drill chuck in it's place, but I can't remove the milling chuck.
I've tried all my biggest hammers to no avail, there seems to be a slot that
takes a tapered thingy that should eject the head, I have tried that but I'm
not sure my taper is the right size. I've also tried whacking the threaded
shaft that runs all the up, but I think I'll break something if I continue
with that. So I guess my question is... Is it just held in on taper or is
there something else that holds it in place, any advise would be gratefully
received.

Thanks
Nigel

All that banging will knock it out of true.

Is there perhaps a draw bar (from the other end) that is screwed up
so holding the Morse Taper in tight?

I spoke to the very helpful tec support guys at Clarkes. There was a draw
bar holding it in, and after removing that and a bit of thought around what
the drift was supposed to be doing, it pop out.... didn't even need by
favourite hammer

Thanks for your help

I'm unfamiliar with your m/c but tapered drift removal is common. Going back
many years I recall loosening the draw bar about a turn and a reasonable tap
with a copper or lead mallet being the norm on some tapered tooling. Having
been 'CNC' since 1987 it's been a while since performing such a task!!

drawbar on it's big brother (CL12-summat), certainly. Loosen it about 2
turns and tap the top of the drawbar is my technique, then unscrew it. Helps
if you make a chamfer around the head of the drawbar to stop it getting
flattened and making the spanner fail to fit..

And don't leave the spanner on 'for next time', i've actually seen someone
do that!! "DUCK!!!" ;-)
