checking dies

[Bob Culver]

The cycle threadform  is unusually shallow. Hence I have asked before if supplied modern spokes and nipples have true cycle threads. Or if any dies or taps for cycle 6 gauge available, but no answer.

And Nick the brass are al 26 tpi which does not corres with 3/8 BSF. it may not apply to old BSF stuff, but many of the cheap taps and dies available today are of vary varied size.

Two piece dies have unfortunately gone out of fashion, but unless used carefully produced way out of size.
