Default Avominor 'Z' screw repair

Has anyone attempted repair or replacement of the needle zero screw in an avominor?

The little peg has snapped off the rear of mine, presumably due to lack of caution when replacing the movement in someones previous repair attempt. I managed to find the missing peg floating around inside, which is nominally 1.5mm diam and 2.5mm length.

I believe that the Z screw is screwed and glued (??) into the backing disc, so am going to try repair rather than drilling the whole thing out and possibly making things worse. My latest plan is to drill a little hole into the disc with a 1.5mm bit and glue in a stainless peg using a tiny amount of araldite. Superglue will creep and sieze the whole adjuster hence the araldite idea.

Any thoughts?
