Hi All
Thanks for all the useful suggestions, especially Zeto for the kind offer. The screw in question is shown below and has a bevel head diameter of 2.3mm and thread diameter of 1.05mm (although I had difficulty holding the thing steady and using the micrometer).
Having thought about it I realised that even if I had a screw I don’t have the correct tap. In addition the speedo has probably been without one screw for some time ....so...
I’ve turned a dummy screw (no thread or slot) and glued this into a hole drilled in the support. It’s a first for me having to use a magnifying glass on the lathe! The instrument face has slots rather than holes for these screws so at least it is held in position at 3 locations and fastened down in two!
Cheers
Howard
