Record CL3 - how to change chuck

[Penllysbach]

Evening all
I have purchased a 2nd hand CL3, but cannot for the life of me find info on how to change the chuck. I want to use a mounting plate ... any links or help pls?
Thanks

If you remove the cover to the belt change compartment there is a couples of flats on the shaft for a spanner then place a piece of wood in the chuck jaws to undo it

With metal to metal contact these can get very tight , When you get it of cut out a plastic washer from a old milk bottle and fit that between the 2 , will help

You don't say if the chuck is a screw-on type or fitted internally in the shaft with a Morse-taper.........

A large spanner on the flats as suggested will immobilise the shaft, but the next step depends on the type of union - screw-on or jam fit.

Thank you all, once again. Perfect info.

When the headstock shaft is immobilized don't use the chuck key to remove the chuck. Open the jaws and use a bar across them as a lever.

Will do, thanks

When the headstock shaft is immobilized don't use the chuck key to remove the chuck.

Mark’s right of course but can’t say we’re all not guilty of doing it on occasion

Last time I used my chuck without a washer (it had fallen on the floor) it jammed on. I put a two foot bar in the jaws and just managed to crack it off, bending a 9mm steel bar through the spindle. I don't use the chuck without a washer now.
