    I've bought all the major assemblies to put my missing quill feed mechanism together and to our far Eastern friends credit the parts are pretty good but I've got to fill in the gaps for numerous bushings and fasteners.

    I'm struggling to understand how the worm gear cradle gets fixed into place, I think I need to sleeve it as it's a very sloppy fit in the housing, but after that I'm lost, there's a slot in it which matches up to a 5/17 threaded hole in the housing but the assembly needs to rotate so I'm presuming there's something else that engages with the slot.

    I've had a good look at the parts diagrams and it's unclear, or is it just a dog point set screw?

    Anyone know?

    Is that part internal to the head?

    Yes it is. It's actuated directly by the feed engagement lever.

    I got the answer I needed, it is just a dog point grub screw just to stop it lifting up.

    I've sleeved it with a bronze bush so it's a nice fit now and works excellent.

    Just the rest to put together now.
