Here is a peek through the side sound port at the bracing of the Kasha/Schneidar tenor #100.
The brown wood at the upper right is the butt block. Below it you can see part of the lower back brace. At the upper left you see five or six of the twelve tone bars, each of a different size and radiating out from the trumpet shaped bridge brace. The flat strip is the center brace of veneer over the center joint in the two piece top. You can also see the knotted strings which are snugged up against that walnut brace. To get this shot I put a light through the sound hole and my iPhone lens up to the side sound port.
This is a better shot.
Now lets put the tentalones on the upper edge of the sides of #101. Before doing that I want to be sure that the heights of the sides are even and proper. At the high point they want to be 3 inches. At either end, 2 3/4. I always make them a little larger wanting to trim down at this point.

Shaving them down to the proper size with this tiny plane.
Done, here are the tools and the residue.
Here we are, All done, tentalones glued on and attached with old fashioned clothes pins as clamps.
