I've needed to dismantle the bearings in my drilling machine and this requires removal of a pair of lock nuts which are round with a radial hole drilled in them, presumably form some kind of "C" spanner.
Naturally I don't have one of these and will now need two of them. They seem trivial to make using a rotary table and a vertical mill (in fact I think I've read about this in MEW as part of an article about making a cghuck for milling cutters). But unlike someone making a chuck for milling cutters I only have a lathe!
Are they available commercially at all to anyone's knowledge or am I going to be doing a lot of filing?
