What is the length of the BB41 starting dog? I believe that the early coil nuts changed in '31 from the BB41 to the BB42. I commend you on your lengthening process but personally would not subject silver solder to the shear stress in this application, also that the 'Mini' nut surely would have been 16tpi UNF which is 60 degree thread angle and not the 55 degree angle of the Austin BSF thread.
Happy to be proved wrong.
Bob
