I have just started restoring my early James ML and I have a brief question I hope you help me with? Can anyone tell me the size of the top and bottom nut securing the fork spring to the forks?
Generally these things are built with 26tpi BSCycl fasteners, But BSF and Whitworth threads are also used. BSF threads get courser as they get bigger 1/4" is the same as BSC 26tpi. 5/16" is 22tpi and 3/8" is 20tpi etc. Ron
