Ramón -> Flamenco 10 - fretboard, etc.. (Jul. 6 2006 2:26:18)

Did a final sand of the soundboard, then 'washed' the top with a soft, damp cloth. Raised the grain, and then went back and sanded up to 600. I then hit the top and top-binding with 3 coats of French polish to protect and seal, after taping off an area for the bridge and neck.
After the final fretboard relief-sanding for the neck angle, and final edge-sanding of the fretboard, I then set up my exact centers (I hit it dead on!), we clamped down the fretboard and drilled 4 very small holes through 2 fret slots. These will then take 4 drills with plastic caps (you can see in the pic), so we can remove the board for glue, and come back to center. WAX these drill bits before glue-up! A board is then used that has holes drilled in it for the centering bits, and used to clamp on. Another board is shaped to the heel for clamping underneath, and a small moon-shape is cut to protect inside the soundhole for gluing.
Bob made a comment that he uses Titebond II, rather than fish glue and other more brittle glues. He referred me to a Dake Traphagen article about the use of a more flexible glue for this step, with a bit more 'give', so I used TB2. Wet-out using a small paint roller, and then a small, metal, tile-set mortar blade was used to draw 'tracks' in the boards.
Set the ebony on the cedar, find your 4 holes, set, and clamp. Cleaned off all the excess, pulled the tape, and it was super clean.
Here's a shot of the board.... Over the last wood clamp, moving up the board, you can see a little red alignment-peg.
