Musiclogic,
I've considered the inserts, but it would be much more efficient and economical to tap directly in the wood. Can you elaborate at all? Any cutting fluid? (Olive oil or something) Can I use this "Bloodwood" or "Purpleheart" to build one of my bridges?

Greenman,
It must be the camera angle. All four saddle/anvil assemblies work the same. The actual saddle piece has a half round boss on the bottom. This boss fits snugly in a groove, cut perpendicular to the string, in the anvil piece. The threaded holes for string height and intonation adjustment are also located in the anvil piece. The saddle piece is held in the anvil piece by the string tension and the string height adjustment screw. All four saddle/anvil assemblies are held securely within the base plate. Here's a side shot of the saddle/anvil assembly.

Cool design. Very interesting.

Whatever sensitivity the tone has to the materials used, I would expect it to be moreso with this design than with most others, due to the way the string saddle is cantilevered out on a beam. (Rather than the usual compression-only setup.) The more flexible the beam is, the more its vibration wil shape the tone.

E.g. if you narrowed up the portion with the saddle forward of the pivot, into a finger shape, and made it out of wood, I would expect to hear a big difference in sound. OTOH keeping it beefy would tend to negate the influence of the material used.

You can use a small amount of oil to aid the cutting process, I have been experimenting with penetrating epoxies and other hardening agents to see if the wood will withstand the pressure on the threading, created by the strings. I have had more success with using brass tube and rod for inserts, and threading those. Like I said, it's still an experiment for me. I only work on the ideas at random when time permits.
