Hi Neil,
Thanks for the advice. I finally got around to cutting a small,
movable walnut block with a slot cut in it. My experience was that if
I kept the block near the existing structure, as you describe, it was
a bit quieter, but not a large reduction. If I put the bridge in the
block and started moving it much closer than that, it quickly lost
coherence and was just uncontrollable noise. Any idea what else I
might try, or how to get the bridge under control (for what it's
worth, the tirant didn't make a difference when I got closer). Would
it help if I posted an top-view image of the geometry of my instrument?

I think you need to try siting the dog closer to the wheel. This
will put the chien further over the main soundboard strut and
significantly quieten it. The mod can be done without major surgery
by temporarily gluing a small block of any hardwood to the
soundboard at a distance from the left edge of the chien bridge
equal to the width of the existing slot. ( Double sided tape works
fine. This will give you an alternate chien position with the right
hand edge of the chien against the left edge of the bridge and the
left edge of the chien against the temporary block.
If still too loud, you can make a separate block with a slot in to
accept the chien and experiment with different positions.
It is actually useful to do this when siting the chien on a new
build as you can easily select the volume required before
permanently gluing the bridge in place.
