I need some help on how to accomplish measuring for a part.
Attached are a couple of pictures of my problem. The part is quite small and I need to make a screw that will fit a threaded hole. (of sorts). The hole will pass a #41 drill (.096) and the threads look to be around 48tpi.(give or take)
However a 4-48 (and a 4-40) won't thread in. A 3-48 is too small. It just falls through.
The part is a rear sight from a pistol made in the US around 1910, so it's not likely to be metric.
Any secrets or hints on how I should proceed?
