Steingraeber factory pictures, bridge agraffes & adjustable vertical hitchpins

[Ric Brekne]

Hi Calin

I almost included this in my last post, but seemed to remember upon my 
initial reading of your experiement that it did not really bear on the 
agraffe discussion. I just had another gander at your experiement and 
dont see the direct connection.  Your experiment deals with the duplex 
and counterbearing angle questions and its conclusions agree (not 
suprisingly)  perfectly with Ed McMorrows  "de-tuned" duplex idea 
published some 15 years ago now I think. 

Cheers

I have a feeling that everybody is making things much more complicated than
they really are, about the way bridge agraffes work.
I have no scientific measurements or formulas to back my own simple
explanation, just a few experiments and the fact that bridge agraffes
performed pretty much the same way I had imagined before I had a chance to
hear one for real.
