That was done on a sixty year old Atlas lathe with a homemade collet adaptor to ensure concentricity.


Good! I knew it must be possible some how. This should looks good!
I've just had another idea for mounting the Z ballscrew. Thread the end of the ballscrew M10 and drill and tap the top of the head casting to take it with a grub screw at the rear to lock it in place. It should all fit without any other mods. The ballnut has to be fixed above the motor in it's highest position so the assembly will be quite tall.
