Making the neck


20180827
I also began to make the neck first by squaring the blank.
Squaring the blank will make marking the dimensions much easier.
Also I tried to plan the length so as to optimised the material used.
These necks will be elevated design so they are longer than usually.

I saw the scarf joint and clean the joint up with block plane.
Before that I clamp a guide block to ensure that the saw is tracking properly.
Then I just need to make sure the saw stick to the guide block.
If the sawing is good the clean up is minimal.
During clean up I just need to ensure that the surface are straight and aligned.

Both necks done. 2nd neck was done similarly

I made a new head template for the new guitar.
Basically mirroring 2 pieces then join them together.
It has straighter curves more inspired by Simplicio style of head which is easier for carving too.

I jointed the cut-off from the back to form the headplate.

The tuner holes are drilled next.
I have the jig from LMI to guide the drill bit.
Just need to make sure the holes are aligned properly for the 2 sides.
I draw a centre line and extend the 3 lines and use a square on the other side to align the intersection with the centre line.

Next I saw away the excess headplate at the fingerboard end.
I had to make sure that the headplate is square to the fingerboard surface.
To do that I use the guide block to saw.
After sawing, I clean up with my chisel.

Next I drill away the waste in the tuner slots.
I use a smaller forstner bit than the one at the start and end of the slot.

Majority of the waste drilled away.


Excess neck was cut from the main neck. The excess portion will form the stacked heel block.


20190328
Next I chisel away the waste the tuner slot.
The final sanding still needs to be done though.
I also cut the heel block making sure the grain alignment is the same as the neck.
This will ensure that during the carving stage will be easier.



Chisel the waste


Mostly chiseled away. Rest will be straighten by sanding.

I clean up the slot by filing and sanding.
Next I cut away the piece for the elevated fingerboard portion.

Cutting the top to plantilla


20181219
Next I draw the plantilla outline on the top.
After that I saw out the top leaving about 10 mm of border space at the edge.
When I am doing tuning, I will trim the top nearer to the actual plantilla.
The excess edges will affect the tuning results thus it needs to be as close to the final shape as possible.

Finishing the guitar


20180710
After 2 years of playing the guitar, I finally get around to start finishing the guitar.
The string broke so I removed the string and started the finishing process properly.

The sound has developed to be very good.
In terms of sonoriy I would rate it the best amongst my guitar. (2nd is followed by Guitar #5)
Other guitars were generally great at the trebles but OK at the bass sonority.
This guitar has both clarity, separation and great bass sonority.
I attribute this to the bracing and the low air resonance.

First I sanded the top even with various grits: 150, 240, 320, 400, 800, 1500.
Then I pore filled the rosette ring with CA glue.
I tape up those areas which I don't want to coat with shellac.
Finally I coated the surface with thin coats of shellac without any oils.
I noticed some patches of unevenness on the rosette area which means I did not sand it even after the pore filling.
Likely I will need to remove the base coat of shellac in particularly the rosette area.
But the grain really pops out after the shellac is applied

Some more polishing to go.
The shellac build is good but after spiriting off I lost some of the shine.
Hmm I am supposed to burnish the surface to compact the shellac but with the bridge in place it's kind of hard to do that.
The excess oil were removed with paper towel.
Those hard to reach area (e.g. bridge area, area besides the fingerboard) are easier to reach if I put a coin into the mueca during the polishing.



Shine is there but I will need to level sand the surface


20180731
I level sand the surface using oil and 800 grit.
Then I followed up with more polishing.
The effect looks much better

The surface is smoother after the level sanding.

I began to finish the back.
I stopped a while as I was thinking what to use to finish the back.
In the end I decided to use shellac.
Pore filling with dust wasn't working out too well.
In the end I use pumice.
The trick to use pumice is not to apply too much of it.
If too much is used it will get tacky and discoloured.
When that happens use more alcohol to level it out.

After a few bodying session, the coat builds up fine.
I polished a bit and things looking good.
I level sand a bit in between.
Some pores are still quite visible so I just a bit more pumice to fill them.
That's the good thing about using FP and pumice to pore fill; you can always go back and do it any time.

After a few sessions of polishing this is how it looks.
I level sanded a few times.
There are some along grain graduations though so when I do spirit off I did it in a traverse direction.
It did level it a bit so i think i will continue a few sessions to level them.
