[modeleng] Re: More Mystery thread

Harry,

I'd have thought it would be BSB. Whitworth thread form is with rounded 
crests and roots according to my Mechanical Engineers' Handbook.

I'm not sure what you used for a degree symbol, I use Alt 0186 which gives º 
(that was a degree symbol in the composition here, but I wonder how it will 
come out).

Regards,

JohnP

       Thanks Tel, John, IDP, etc.  My next question is, considering it's a
Bantam Cock and assuming it was made to the "words & music", which of these
two threads is it likely to be, and do both of them have rounded crest &=
 root?
       I'll  probably single-point the thread on this adapter and in that
application the whether it's 55=B0 or 60=B0 thread form is incidental, but
rounded crest & root vs. angled thread does definitely make a difference.
       BTW, after the 55 and 60 above I placed a "degree" symbol (a small
circle) and I was just curious to know if that is what actually appears.

Regards,
Harry
