Threading die's always had a taper on one side, the side marked with the size and logo, the over side did not have a taper, so you could thread up to a shoulder.
Today whilst trying to thread 5ba using a die supplied by a reputable dealer i could not get anywhere near the shoulder.
Is this something common to the Chinese supplied die's, does anyone know if the likes of dormer, presto are the same?
Thanks all.
