Gossen Luna-Pro dial repair

[colyn]

I have a good working Gossen Luna-Pro. The only problem is when changing the ASA I have to press down on the clear dial face. This clear face has a thick area which is supposed to fit down in the slot of the ASA metal part of the dial but is raised up away from it. What is the best way to remove the dial to fix this issue?

I have done it and I can't remember how! In any case the meter has to be open by removing the thin aluminum plate, use a razor blade or x-acto blade to avoid bending it. The brass screws heads are clearly visible, loose them then the two shells will come loose. Keep in mind the main switch pivoting pin is held by the two shells. Once you have the top half in your hands you can see how the dial assy is held together. Delicate work but fun.

Why don't you send it off to Quality Light Metric, Hollywood, CA for a CLA and repair? Mine was off one f-stop over the whole scale.

This one is dead on as tested against my recently overhauled one..

I have a similar lunasix, the first model, the one with two buttons. I (almost) completely disassembled it as it was not working. After fixing and calibrating it, I tried to take the dial apart just for cleaning, and in my meter, it is not easy or evident. In fact, I don't know how to do it without breaking something. The sixtino (also gossen) is much easier, just unscrew it. Perhaps your is different.
