Article about bridge agraffes - function, types

[RicB]

Hi folks.

I've been looking into the whole idea of bridge agraffes as well this 
past couple years. Strikes me that the major problem with the standard 
bridge pin solution is that half of the (string) clamp is made out of 
wood.  Otherwise the idea of offset pins seems quite sound and about as 
simple as it can get.   So,  I submit the following idea for front and 
back pins. Made of brass and standard bridge pins... the inserts are 
mounted into a standard wooden bridge using epoxy for solid attachment 
and will allow the builder to determine exactly the desired string 
angles fore and aft of the bridge simply by determining the height of 
the inserts.  The string does not touch the wood of the bridge surface 
inbetween the inserts at any point.  The pins in the inserts are 
vertical in orientation and there is a slight shallowing of the width of 
the pins at the base of each pin where it enters the insert to function 
as a lock for the string.  Combined side bearing and this shallowing 
will hold the string tightly to the surface of the insert.

I've made a few prototypes and plan on installing them in a beater early 
in the comming year. 

Cheers
RicB
