Arnak,

Will this post help you at all?

If you swap your dimensions for the Myford ones at the beginning, then screw it onto your spindle nose, then follow along the rest of it dot by dot.

Hi John,

Very nice, thanks very much for that. ;D

I've bookmarked it for reference.

Bez,

Not just Whit, but BSF and ME threads also use 55 degrees, and most probably a few others as well, but these three are the most common ones used.

Thanks John
I thought all Brittish 55o threads since about 1850ish were all whitworth form (ie same root shape and same crest shape) including BSW, BSF, BSP and BSB etc. (all those not 55o are not whitworth form) BA, BSC, Acme etc.
Is that not the case? ???

You are quite right Bez, I wondered why you came back with such and understated reply, not like you at all.

I had misunderstood your text, purely because I tend to refer to a thread by what it is, rather than it's form.

BTW, two of my favourite heroes, Ike Brunel and Joe Whitworth.
