Rather than hijacking another thread, here is a picture of the Z axis gib locking arrangement on a Hercus Type 0 mill, and the handle I was intending to replace it with. The problem is it's currently 8 mm thread, and the Hercus is 5/16 BSW so I'm now just considering options as to how I'll convert it. The Y axis will be more of a PIA as it's right on top of the Z axis winding mechanism. I may not even be able to get a handle like that shown in there so will need to consider that further.
