Could they be cycle wheel spoke thread ? I seem to remember that there is
(was) a thread standard to suit "piano wire" (SWG) sizes. Don't know if
they are/were the same.

Subject: [modeleng] BA/ME Thread Query
Hi All,
I'm fitting point rodding on my gauge 0 (live steam) layout and have
some old but unused brass "forks" to connect the rodding to the bell
cranks. The forked end connects to the bell crank with a split pin, and
the other end is tapped to thread onto the end of the rodding.
But I need to thread the ends of the rodding and can't figure out what
the threads are on the forks- they seem to be somewhere between 7BA and
8BA. Both threads work after a fashion, the 7BA a tight fit and the 8BA
on the loose side, but neither seems really right. And the smallest ME
thread I know of is 1/8" x 40tpi, which is too big. Am I missing
something here? These forks were mass produced by Bassett-Lowke,
MilBro, etc, so must have been to a standard thread.
Any thoughts?
Thanks as always.
