Does anyone know of a source for the purchase of the knurled screws of the kind used for securing eyepieces, diagonals, reducers etc? I have lost a couple, and damaged one as well, and could do with some spares. Typically, the ones I need are all of different sizes, (screw pitch, diameter, and length) so it may be that I have to re-drill and re-tap all the holes, so that I have a standard thread, which would make replacement easier.
Any suggestions would be very helpful.

Take your diagonals, adaptors etc to a Bolts & Fasteners shop. They can read the threads and supply the matching bolts in all sorts of lengths. And usually you will only pay anywhere from 50c to $2 per bolt at a bolt shop. Often you also have a choice of steel, Stainless, brass etc.
Good idea to get 2 or 3 of each as spares for when you lose them again.
