A general question. What threading system was used on the Bren Tripods? S.A.E. or Withworth or BSW or ??
Area I'm working on are the leg pin threads. It seems that they are 14 tpi. Dia .625 inch or 5/8 inch. Which is not a normal SAE size, but they are available. Or does anyone have any other size for the leg pins?
Granted I could just replace the pins and collars by ordering them from brp. But I like to clean them up by chasing the treads with a tap or die as needed.
FYI it seems that a M12-1.50 tap fits the threaded hole on the front AA adjustable leg. Not sure if that is the perfect one but it sure cleans out the threads.
I've been rebuilding the leg pin areas. I'll take pics and post at a later time. Simple enough but you can have problems with the holding pins and the collars. Well have about 5 more setups to finish up.
THANKS for any help in advance.
