How do these things grip the leadscrew shaft? Is it grubscrew, pin through, engaging the dog clutch handle interface some mills have? I imagine a taper lock as on pulleys is too expensive. How do they cater for lo9ts of different shaft diameters?

How did you arrange the self eject function for tooling?

Hi Robert,

The new collet chuck arrived today so I’ll be fitting the ‘self ejecting’ drawbar soon, I’ll put some pics up if you like.

The gear that fits on the end of the leadscrew has three drive dogs the same as the handwheels. It is held in place by a grub screw.
