Making the neck

I had one neck (Sapele) with the scarf joint already glued for #3.
I am going to do another (Cedro) for the #4.
So with my 15 degree jig I saw the scarf joint and clean it up with plane.
This has more or less become 2nd nature which is quite easy.

Next I will be making the head plate for the #3.
I joint 2 cut-off from back of #3 and it's ready for gluing onto the head.


Neck blank clamped for sawing the scarf.
Sawing the scarf.
Sawing done.
Clean up the scarf joint with a plane. Check for flatness and squareness.
Plane the thickness of the head before gluing. It's easier to thickness 1st before gluing. If thickness after gluing it has to be done on he reverse side if not the length of the neck will be shorten. Reverse side has some difficulty in plane though.
Jig prepared for gluing. Clamp 2 piece of wood to support the 2 head plate parts.
Apply glue
Push down into the jig. The width between the 2 pieces is slightly smaller than the 2 pieces. When you push it down it is clamp tight together.
Add a weight on the center seam.
Head plate done.
I glued the scarf joint for the #4 guitar.
Not perfect as I need to take it apart reheat the HHG and glue it back.
I think my HHG has gotten too thick I need to thin it down a little.



Heating up the surface

Glued and clamped

The neck gluing didn't turn out to be perfect, so I tore it down and redo the gluing.
That's the good thing about using hide glue.
Still it's very hard to make it come apart; I need lots of heating and inserting the spatula inside the small gap.
Some 1/2 hour or so the 2 pieces came apart without much damage.
I scrape the hide glue remnants on surface and re-plane the scarf.
This time round I check for perfect fitting include the reference edge.
Once I am satisfied the 2 parts are ready for gluing again.



The scarf came apart finally after lots of heating and spatula work.

2 necks ready for gluing


Now is the gluing time.
I prepared the HHG and then heat up the surface and started gluing.
One thing I noticed is that my HHG is slightly too thick so I added some water before I glue.
The texture is just nice.
I heat up using my hairdryer and apply hide glue to the surface.
The neck body is clamped down 1st.
After that I glued the head and clamped in 2 blocks to apply constant pressure.
Similarly I repeat for the other neck.
Now this other neck is for another project; I shall elaborate more of that later as now I have 3 guitar projects on-going at the same time.

After that I work on the headplate for my #3 neck.
I plane 1st and then scrape smooth.
The ink lines for IRW are pretty nice; just nice for the center seam.
So I don't really need any decoration for this guitar which is the main theme of the ornament for this guitar #3: natural

All the veneers ready for gluing

Next I began to glue the veneer.
As for the head plate I wanted to wait till the veneer is trimmed so that I can drill some guide holes.
I use 2 layers of maple followed by 2 layers of walnut and finally 2 layers of maple again.
The neck wood is dark so I have dark(neck), light(maple), dark(walnut), light(maple) and dark (head plate)
Total thickness of the veneer is 1.42 mm and head plate is about 3mm.
I will trim the reverse side of the head once the tuner holes are drilled.

Clamping down the veneer

As for the other 2 necks they are glued pretty nice!



The other 2 necks glued.

Now the #3 neck is ready for gluing on the head plate.
I didn't glue it together with the veneer is because I need to align it centrally.
With all the protruding veneers it's pretty hard to align it.
After I trimmed the veneers, I drill 2 guide holes on the headplate on those area which will be sawn away later.
After that I prepare the HHG; and then I apply the glue; and finally clamped it.
To cater for the slight movement during clamping, I didn't clamp too hard down at first.
After tapping here and there to adjust the alignment, I apply more force on the clamp to stablise it.



Trim the veneers


For the ends I use saw instead of plane as it's easier.


Drill the guide hole


Apply HHG and heat it to prevent it from gelling too fast.


Clamp it down after adjustment.

The head plate gluing looks good.
Center almost perfectly to the eye on the center seam.
After that I saw the headplate at the nut end so that the headplate ends in perpendicular to the fingerboard.
But I can't find my old block, which was also 15 degrees head, and so I make another one by shooting a block of wood on the plane.
After sawing the excess, I clean up with chisel.
Then I started to taper the sides with plane.
This Sapele is much harder to work with compare to Spanish Cedar.

... and rebate plane


Nicely done.

The head stock look. Still need to clean up.


I began to work on the head stock shape.
Well I could have use a base shape and router with a trimming bit to follow the shape attach to the underside but I chose to do it the traditional way using chisel and rebate plane.
I draw the marking on the head and started sawing away those waste parts.
Those intricate one I use chisel to chisel away.
Finally I clean up using the rebate plane in various orientation to clean up the surface.

Saw away the waste part


Saw first and then chisel the step before the 3 Torres tomb lopes.


Saw other kerfs to reach in between the 2 lopes


Start to pare away the in between waste


Headstock almost done after cleaning up with the rebate plane.


Next I drilled the tuner holes.
With the LMI tuner jig it was quite simple.
Unfortunately I am using the 10.31 or 13/32 drill bit, and the tuner jig is meant for 10 mm.
Out of the 3 holes only 2 is large enough to drill thru'.
So I drill 2 and then turn the jig over to drill the 3rd one, making sure the center hole is correct (by inserting another drill bit within.
One fine day I should just try 10 mm instead.



Drilling the tuner holes


Done with one side.


The other side also.

Next is to drill the slot hole and cut.
I marked out the slot hole and drill them.
Next I use the coping saw and saw out the waste material in the slot, followed by chiseling the edges to the line.

I plane headstock thickness (at the back) abit to make it less bulky.
Next I saw the front slot and chisel a slope for string clearance when tying to the 1st string and 6th string tuner barrel.
The mini douzuki saw I bought recently was very useful; more handy than my usual big ryouba.

Splitting the Brace

Though I haven't really completed the rosette for #4, I decide to work on #3 a bit more.
I began to prepare the brace blank.
I had a good brace blank from Shane of High Mountain Tonewoods so splitting them was quite easy.
My previous experience wasn't easy as the LMI stock had quite some runout.
This time round at first I try to chisel and then split but that didn't quite work out.
So I ripped saw the 1st part (cater for more allowance, I need 7mm wide I but I split at double width 14mm), and then use the chisel to split.
After that I analyse the split and look at the grain and then plane it to shape.

Using the chisel to split

Planing to size
After splitting and planing the brace, I shoot them to get a good gluing surface.
Following that, I saw the brace into 1/2s since I only need 7 mm wide 3 mm tall, I can get 2 braces from one blank.
Each is about 14mm thick.
After some work here is roughly the brace layout.

New tools!

Well I got my first Lie Nielsen tool and it's a router plane!
I also bought a old Stanley #15 Jack plane.
Looks like I got some tuning to do.
There will be an iron upgrade for the Stanley but the IBC plane iron has not arrived yet.
Here are some pics.



The jack and the router plane.


3 work horse plane: Stanley #5 Jack Plane; Stanley #4 Smoothing plane; Chinese wood plane


LN router plane. No wonder LN is so priced in woodworking scene. The quality is excellent. Can't wait to try it out.

I tried out the router plane it works like a charm.
The adjust is very easy and the cutter cuts pine like butter.
The only thing now is to get the narrower blade for rosette channel routing.

This is the woodcraft IBC match pair of chipbreaker and iron. It's a whopping 1cm thick iron! I probably need to file the mouth bigger and adjust the frog back...

Thicknessing the top

Although the rosette wasn't perfect, I continued on working on the top.
I use my good old #4 Stanley plane for the thicknessing.
When I started planing I noticed that there is some run-out so I had plane one side of the top and then turn over and plane the other side in the opposite direction.
If I don't do it this way there will be some tear out.
When the rough thicknessing is done, I cut the sound hole.
The bridge area of the lower bout is about 2.5mm and perimeter about 2mm.
Right now the upper bout is still pretty thick but I plan to take it down to about 2mm.
The top weighs about 159g which is heavier than my #2 top (133g before bracing).
I plan to reduce the UB further to try to bring it down to 140g region.



Planing the thickness down using my #4. Due to run out I had to plane in an opposite direction for the 2 different sides.

The shaving.

Cutting the sound hole using my circle cutter. I cut one side then flip over and scribe the other side.

Weight of top is 159g

Can see the silking on the top after planing.

The #3 top and the back

After some more thinning of the UB, it dropped to 145g. Well I guess I can leave it for now.

The bracing pattern for this build. It's slightly different from Torres fan. I leave out one fan on the treble side and add a treble bar. Also I add in the Bouchet bar across traversely at the bridge region. On the bass side I remove the closing bar.

Some more new wood stock...

Well I have the ZAS or WAS (Zoot/Wood Acquisition Syndrome).
I just could not stop myself from getting more wood.
What did I get this time round?
Some Osage Orange, IRW, and HRW.
Osage Orange is commonly used for making bows.
It is a very dense wood and a "drop-in" replacement for the famous BRW according to Alan Carruth.
Well since I can't get BRW so I might as well get a the nearest replacement.
The IRW I got was premium set dark and straight grain.
HRW is by far the most dense wood I have in my collection.
