The enclosure around the Z screw nut extends down to the honking plate and bolts on from below. To release it I remove the bolts.

The snag is the screw wants to be as close in to the quill as possible but the tin housing at the top of the machine overhangs, limiting the vertical space. I didn't want the screw to extend below the honking plate.

On the Mk 1 I had one 8mm bolt in the hole where the depth stop used to go. On the Mk 2, I used two 8mm bolts so I could extend the screw down to the bottom of the honking plate, passing between them.

It is a weak point because on the Mk 2 I cut threads in aluminium rather than steel which will wear and, eventually, strip. Hopefully I have cut them deep enough to see me out, one of the advantages of getting old :naughty:
