Early swivel joint for commutator rod?

Post by Tbird » Wed Jan 17, 2024 6:00 pm

Going through parts, found this swivel joint.
Doesn’t look like the ones from 1911 and up

Threads right on to a commutator rod.

Or a throttle linkage on a RHD car.

According to the Ford archives, two styles were used during production. One was a Ford designed part and the other produced by an outside source. The one shown is very similar to the outside source print.

Ron, is 7/32" equivalent to a certain wire gauge? I have found that spoke nipples from Wire wheels have the same thread as the T carb linkages and timer rods. I have used a section of one nipple as a locknut against swivel end on a carb linkage.
