Go-baring the top and some nice wood

Being a spare time hobby for me, luthiery hasn't caught much attention lately. Here's some latest activities over a pretty long period:

- preparing and gluing the top center seam for Jouni's guitar.
- preparing and gluing, re-preparing and re-gluing the back center seam for the same. The Ultimately Good Looking Cocobolo (UGLC) seems to be a very tricky wood to be glued. It's a very oily wood and seems to be rejecting almost everything I have to offer gluewise. It remains to be seen, if the latest trick'll do the trick.
- preparing top bracing for Jyrki's guitar. This has become a lot easier with the concave discs I made. I'll just simply put some sanding paper on the disc and sand the braces in right shape to fit the curvature of the top. Less guesswork, faster and more precise glue seams.
- Gluing down the bracing using the Go-Bar method, AKA AAWSIBTSP (Awful Amount of Wooden Sticks In Between Two Slabs of Plywood).

Nice detailing in the wood

The sides have a distinctive pattern too


Laying down the bracing pattern for the 00-sized guitar. For some reason the lowest two braces run the wrong way in this picture 
Go-bar gluing the bracing - first all the rest of them

And then the center x-brace too. It took 26
 bars to get there, I believe.

Global rosette

Here's two shots of the 00-top with rosette installed. Top is european spruce, very stiff and nice looking stuff bought from a chinese seller through american ebay. Rosette with East Indian rosewood and  New Zealand Paua abalone is bought from a taiwanese seller in ebay. Put together in Oulu, Finland. Now figure that globalization out!

The rosette channel was cut with a dremel tool attached to a home made routing base. Two parallel runs was sufficient, as the rosette fits in a single wide slot. Soundhole was cut with the same tool, only deeper.

The rosette opening is a bit offset to get the grain direction right. The opening is nevertheless covered by the fingerboard.

This appears to be one of my cleanest rosette installations so far. Experience? Luck?
