Preparing for Assembly

20121024
Well the sides are bent, and next to come is assembly.
First I had to saw the sides to side to fit into the 2 halves of the side mold in the solera.
The rear part was easy I just mark out and saw.
The front part I had to bend the sides a bit and mark and then saw it.

After the 2 are cut to size, I began to shape the front drop to fit the solera.
I had traced the line previously, but I just saw and plane until it fits the solera.

Following that, I use the sliding bevel to mark the angle in the heel block and transfer to the side to saw the triangle shape in the front.
I also measure the distance from the center line based on the heel block.
I fit in the top and heel block to test the fit of the assembly.
I also cut some over-sized dentellones and try to see the fitting.

The end block was one half from my previous build.
I never like thick end blocks so my end block I always saw into 2 halves of about 15mm thick.
I just fit the end block to shape for the slight curvature.
Now once I cut enough dentellones I am all set to assmeble the guitar.

While at it I also think how to install the side braces.
This build I will include a side brace at the lower bout that is possible to attach some weights to the sides.
This is from the Trevor Gore book where heavy sides will impose a big impedance to the top and thus prevent the top vibrations from losing to the sides.
This will have a louder volume impact.
Well I will trying this one out for this build to see / listen for myself.
One thing I am still undecided is to use brace of what grain orientation.
I wanted to use the grain direction parallel to the sides (as per end block) this is so that it act as a giant dentellones too.
I was thinking of doing 2 similar for the LTB and UTB support.



Saw the excess end from the sides


Mark the center line for the neck end of the sides


Both sides trimmed to length.


Trim the upper bout part to fit the "dropped top" area


After that follow up with plane to make the sides fit the dropped top profile in the upper bout.


Using the sliding bevel to mark the angle in the neck slot.


Transfer the angle to the sides at the neck end. Must be careful of orientation. The offset is measure from the center of the neck.


Trim the sides.


With the heel block. The sides fitted well. I haven't trim the wedge as yet...


End block done also.


Using dentellones for the 1st time. I'll shorten the height a bit to match the height of the UTB and LTB (about 17mm).


Profile the heel block to be more curvy than rectangular block

I continue to plane more Spanish Cedro to size for the dentellones.
I use the original 2 as a reference rail to plane the rest of the blank to the correct size.
I use my small douzuki to saw the blank; it's very accurate



Sawing the blank to size using the douzuki saw. It's very handy and accurate.


Planing the blanks to size using the original 2 as a rail. When it reach the same thickness as the 2 reference rail, the planing stops automatically. Simple but effective concept.


Some blanks prepared but still a long way to go to cover the entire guitar perimeter.

The dentellones blanks are all about the same size height, I did using using the 2 reference rail method.
Next I use the miter box to cut them to the same size.
I place them dry in the box to test run.
Now all set to assemble.



Cutting more blank.


Plane a curve into the blank


Cutting them into dentellones using miter box.


Dry assemble
