Nick & Bob,
I'm a bit confused here. As far as I am aware, BSC does not come in a
13/16 " size. While there appears to be a select few sizes that come in
both 20 and 26 TPI, it does not include 13/16". In fact, my reference
charts show that the only sizes in BSC that have both a fine and coarse
thread are... 7/16", 1/2", 9/16", 5/8", 11/16", 3/4".
I missed the history on this thread but we are talking about a British Bike
here and not a Healey?
Nick do you have a copy of the reference chart you got this information
from? I'd like to include it in my reference material since I'm writing
another article on British fasteners for Austin Healeys.
Thanks,
Curt
