Ive been working as a clockmaker and occasionally made screws for a
local black powder gun owner (all the right tickets) and am in the Uk
a couple of points 5BA is very close at .59mm pitch but the dia is up
Yes, I spotted that one. Unfortunately, I want to keep the telephone as
original as possible (I don;t want to drill out and re-tap the holes, if
I did, I'd pick something more common than 5BA :-)) Nor do I want to
replave the termianl strips with new ones if I can avoid it.
a bit at 3.2mm (model engineer use this size)
I do have a cnc so can cut arbitary threads, so if you dont find any ask.
I 'only' have a manual lathe, but needless to say I can set it for
cutting a 0.6mm pitch htread if I want to. However on something this size
(and where precision is not that critical), I think a die in a tailstock
die holder would be a lot easier. And I am pretty sure I can get the die.
Although, perhaps it doesn't fit with my normal cheacter, this time I'd
rather buy the screws than amke them :-). If I cna;'t then I start
machining metal...
