Hello,
I'm trying to clean up some old telegraph keys and sounders and have run into some strange screw threads. The screws are 32 threads per inch, but diameter is slightly large for #8 and far smaller than #10. These seem occur most often in the pivots supporting the key levers.Does anyone know what I have here - and where taps, dies or screws with this thread may be available? .I searched the internet for such Case study example to find thread, but haven’t found anything useful for me.Please help me out.
Any help will be appreciated.
Thank you.
