Found another part that doesn't fit as it should
The hadnwheel coupling houses the detent spring and ball for the quill feed engagement plunger. When I fit mine to the shaft, the hole doesn't line up. I couldn't get a good picture of it but this is what it looks like looking through the hole that holds the set screw in place:

The set screw is hollow to accept the springs and has to screw down flush to the surface of the coupling, otherwise it will bind on the feed trip bracket. As it is off centre, it locks the detent ball, preventing the feed from being engaged.
I took it off and screwed a bolt into the hole and I see the problem. The hole has been drilled at an angle, not straight (to the centre). I can't rotate it, as there is a key that fixes the coupler to the shaft. I've alerted Kondia to see what solution they offer. I'll probably just end up making a new one.
