I've just been looking at a beam compass on ebay, #2227638979, and the knobs
have been knurled so that the knurling 'curves round ' the knob ... does
anyone know how this was done? ... has anyone done this themselves? I'd
like to know as i have an old mechanism with a knob like this missing and
would like to restore it.
TIA to anyone shedding light on this problem.
