Preparing for assembly

Before assembly I need to cut the top to shape especially at the 12th fret part where it is attached to the neck.
I simply saw at the line.
After that I trim the top to conform to the side profile.

Also I cut the side to fit in the heel block.
At first I nearly mark the wrong direction.
But when I put into the solera, I discover the triangular shape orientation is wrong.
It really pays to be careful.

Normally the angle is measure from the bottom of the heel block
But in this case the heel block is blocked by the elevated neck extension.
So I had to measure from the top and hence the orientation error.
The right way up is the wider at nearer to the top and narrowed into the heel / back region.

Align the block to aid the sawing.

Ready to be sawn

Done. You can see 2 marking; outer one is where the sides' boundary.


This is where I marked wrongly. I only realised it when I put the side back into the solera
and notice the shape orientation of the triangle is wrong.

Using the marking gauge to get the angle. The additional block is to make sure the reference edge is constant.

Mark on the sides.
The distance reference from edge by measuring the center width of the heel block and divide by 2. The width is 28mm and 1/2 of it is 14mm measure from the center.
The angle will touch the marked point.

The triangle shape orientation is correct.

Assembly fitting

The sides orientation is correct

The wedge in action. Need to cut a more fitting wedge though.

Checking the fit of the wedge. The actual wedge will be at full width

Test fitting without the solera.

Following that, I begin to make the actual wedge for the side slots into the heel.
I cut 2 pieces and then plane to fit.
Also I began to plane the end block.
I saw the end block blank into 2 halves and plane the thinner one.
My end block ended up about 10mm thick.
I am thinking it might not be sturdy enough.
Again I was checking the curve with the mould when I plane.

Checking fit for the right wedge.

The wood is just as scrap but it works well for a plane stopper like a bench dog

Dry assembly. Both wedges and the top wedge all working fine and well fitted.

Dry assembly to see how the elevated fretboard looks.

In the mould with the neck and wedges in place.
Some asymmetry there.

Another view.

Well I must start to think of the sequence of assembly.
With the elevated neck in place the assembly is slight tricky.
I must also decide whether to glue in the wedges or not or simply wedge in will do.
From what I knew, Romanillos only glue the other side of the wedge and not the wedge face that is in contact with the movable piece.

Making neck

Well next step is to finish up the neck, but my forstner bit hasn't arrive so I can drill out the slot hole.
I bought a cheap set from Ebay but the bit was blunt and doesn't cut at all.
That's really you get what you pay for.

Anyway at least what I can do is to drill the tuner holes since I have the jigs ready.
I first plane the slope of the head which I have marked out earlier.
I use my rabbet plane and chisel to get to the final mark and check for squareness of the edges.
After that I mark the center of the head stock and the center line for the tuner jig.
I insert a 2mm plywood to offset from the face of the headstock and align the center line of the tuner hole jig to the marked center line.
Clamped everything together and use a tape to mark the depth of the drill

I started drilling but encounter a problem, one of the tuner jig hole doesn't go thru...
My brad point drill bit which I got from LV broke at one of the side tips...
Argh... I had thought a reputable LMI would do a quality check before the ship.
But anyway I had to improvise and drill 2 holes and then flip over to drill the 3rd hole.
I finished up the tuner hole drill and now to wait for 5/8" bit to arrived.

Saw a slot to enable planing of the slope.

Chisel the waste area away. Now to start planing

Both sides done. Center line marked

Both sides checked for ease of turning of the tuner.

What's next but to drill the slots and my Freud forstner bit arrived just in time and it's sharp.
Well I marked out the slots and drill the end holes.
After that I thought of drill more holes in between but in the end I decide to use coping saw to saw the in between waste.
Finally I parred the edges to the line and sand it smooth.

Next I proceed to carve the string clearance slope at the slot near the nut.
This is to allow the string to go down to the tuner barrel, without touching the guitar head or at least allow it to go smoothly and not across a corner edge.
I first saw the slot and then chisel the waste.
It's just that straight forward.

All slots sawn

Start to chisel the slope

Done.

Slots done with the tuner in place.

Next I began to rough shape the heel area.
First I tried to saw with a coping saw... it's damn difficult due to the width of the neck.
Well I cut some some vertical slots in the heel to allow intermediate breaks for the coping sawing.
For the straight part I use the ryoba to do the job.
After that I use my rotary sander to shape the heel.
Now it's ready to be attached to the neck.

Both side done.

The detail carving will be done after assembly.

I did further shaping of the neck, the curve at the joint of the head and neck.
I use coping saw and cut then shape by the sander.

Cutting the other side. The coping saw direction need to be flipped to the other side.

The end product.

The heel area also narrowed

Smoothen the shape of the slots to correct some asymmetry.

As the concluding saga of the neck making before assembly, I glue up the heel block and carve the head.
Well after assembly, I still need to carve the heel and neck body profile.
I use HHG for the heel block and align properly with the markings I made.
As the block slips I basically held in place with hand until the glue grabs before I clamp in.

For shaping the head, I use chisel and my rabbet plane.
The rabbet plane works amazing well; partly because I am still not very skillful with my chiseling.
Of course I cut using saw before chiseling the waste to the line and smooth with the rabbet.

Done! Looks nice
And now to assembly...

Well I supposed to leave the carving of the heel to after assembly but I just couldn't help it.
I rough carved it anwyay.

Taking shape now.
