Default Re: Avominor 'Z' screw repair

Thankyou chaps.

The gist of it is that i am hopefully making a functional Type E from two defunct units. They are broadly contemporary with each other (1949 and 1944) but the former has an o/c movement and Z screw problem and the latter is giving some low and random readings and is very reluctant to function on K=1 for reason i have yet to fathom. The latter also doesn't want to zero consistently either.

The switch points on both appear to be ok.

The Z screw is nickel over brass, screwed/glued into a plastic disc at the rear. The repair of this is looking good, the other challenges are now under scrutiny!
