At least today the pedels all use the same thread. ? But so much else is totally custom. ?Like the tapered-head titanium cap screws. ? One newish innovation is that all the screws on my bike are marked with a “Min and Max torque” value. Something like “5 - 7 newton meters” by every screw. ? ?I think this happened when they went with carbon fiber.
I have NEVER heard of anyone usimng machine tools to work on a bicycle. ? It is just not done.

Back when I was still into bikes & Campagnolo ruled everyone
had to use different threads in their bottom brackets & pedals
. I had/have a Set of TA cranks & chain wheels & the
threads were different between? TA , to Stronglite , &? Campy
crank sets . I was so pissed when my new to me Campy blacktop
pedals wouldn't fit the cranks . It's actually probably good that
I didn't have a mini lathe or any lathe & mill for that mater
back then. I'm sure I would have ruined a lot of expensive parts
by fixing them .

The thing about bicycle
parts is that they use a lot of non-common threads and gear
profiles and screws with custom head shapes, not to mention
exotic metals and tempering. ? for example, you can look at a
standard bottom bracket and find?34.92mm
diameter threads. ?Not a hardware store size. ?You might
measure and?think
“35mm” and be wrong. ??
I don't know the specs on the gear you need
but, there is a good chance is it a custom-size or profile.
