I need to make a nut to fix up an old Bing toy steam engine made in the 1920s.
The nut is an odd one as it is 26TPI with a diameter of 9.95mm.
I know they make 26TPI by 3/8 inch taps but this is around 9.525mm so this can't be the correct tap.
This same model uses BA threads on it else where but this is not a BA size.
On bicycle forums I've read of 26TPI 9.9mm threads but thats it.
Does anyone know where I can get a 26TPI by 9.95mm or atleast what is the actual name of of this odd size of thread?
I would say it is 26TPI by 10mm which appears to be an odd cycle thread.
I've found a cycle shop that sells bike parts with this thread on it so the tap must exist.
