Jointing the top and back


20180814
I began the build by shooting the various boards: tops and backs.
After making sure that no light passed thru' the joint seam, I proceed to joint the 2 halves of the boards.
I have only 2 sets of jig to clamp the 2 halves so I joint the tops first.

The top is removed from the jointing jig.
Next the back is glued with the same method as the top.
The glue remnants is also removed by scraping from the jointed area on the top.

After the glued dried and more than 48 hours, the 2 backs are released from their jointing jigs.
Looks great!

Prepare the top & back

I had some time today and so I began to shoot the edge of the top and back for jointing.
Same method here using a shooting board and a #5 plane.
Previously I had already almost perfect preparing the seam so today I just touch up a bit to give it a fresh surface for gluing.
After that I began to joint the back using my jointing jig.

The back is done now to joint up the top.

I realised it's kind of hard to separate the build for #7 and #8 so a lot of time I will be doing them side by side.
So I have decided to include both of them in future post.
I traced out the outline of the plantilla and began to saw the outline from the top.
After doing 2 tops the time is up so I have yet to start on the 3 backs. (#7 #8 #5)
At first I use the long reach fret saw with a tiny saw blade for the top but it kept breaking.
So in the end I just use the coping saw.
The coping saw's teeth is very aggressive so I have to use minimal strength and ensure that the top does split in the process.
Luckily all went well :)

I also realise for #8's back it might look better if I joint the other side instead of this side.
Ah well too late to change anything...



Starting on the top.

I began to saw away the excess of the back.
The cut-off will be used for the head plate of the neck.
This has been my practice for part few guitar starting with #2.
For information I started with #5 back but that will be covered in another post.

Following #5, I began to saw the Maple back #8.
The maple was a softer wood compared to the rosewood back of #5 so I took considerable less time for the maple.
However, I need to switch to a fret saw instead.
The reach of the coping saw was not enough.
For the fret saw instead of using the normal scroll saw blade, I twisted a more aggressive teeth coping saw blade and fitted it to the fret saw.
The twist was to make the blade cutting direction perpendicular to the fret saw frame.
This will ensure maximum reach.

For support, I use a piece of wood and keep adjusting the position to ensure maximum support for the wood piece.
This will prevent the wood from breaking.

End of cut


The back done.


Remember I mention how the #7 back will look if I had jointed the other way?
Well I use photo tool and did it instead.
It certainly looked nicer than current joint.
Anyway think I am too lazy to make the change.
I'll leave it as it is.
For view pleasure here's the pic.

In the end I decided to redo the back joint for #7
I have learnt if there is something that I am uncomfortable with it's better to redo now rather than at a later stage.
And so I took out my heat gun and applied some water to the joint.
After some amount of heating both sides of the joint, the hide glue just wouldn't budge at all!
If anyone think that hide glue is easy to remove better think twice...
In the end I just saw the joint instead.
The rest is pretty simple shooting the other side for jointing and glue the new joint.



Prepare to unglue the joint


Began to apply water and heat to the back joint.


After 10 - 15 mins of heating the hide glue joint wouldn't budge at all! So I have to resort to sawing instead.


Finally sawn! This joint orientation looks much better.

I cut out the plantilla shape for #7


After jointing. Looks good.


Saw out the plantilla shape almost done here.

Starting on Guitar #7


20140128
In a parallel build with #8, I will be starting on #7.
The specifications are as follows:
Top: Lutz Spruce
Back / Sides: Madagascar Rosewood
Neck: Spanish Cedar
Fingerboard: Madagascar Rosewood
Headplate: Madagascar Rosewood (from back)
Tuners: Rubner
Bridge: Madagascar Rosewood (18 Hole design) with MOP tie-block plate
Binding: Maple
Nut / Saddle: Bone
Scale Length / Nut Width: 650mm / 54mm (string spacing 41)
Finish: Shellac FP top / Lacquer B&S
Bracing: Modified Bouchet bracing (same as my #3)
Other Features: - Active back
- Sound port
- Half elevated fingberboard design
- 22th fret
- Marker on 7th fret

The unique feature I wanted to try out in this build is the half elevated fingerboard design.
I.e. the treble side of the fingerboard will be dropped down to present the elevated part of the neck while the bass side will remain as per normal.
The good thing about this design is that the elevated fingerboard will not be as confusing as the full elevated fingerboard design, while maintaining the ease of reach of the upper frets.
However it will present more problem:
- The top will be split in order to allow such a design.
- The binding channel near the treble side heel area will be as difficult to do like my #2
- The neck/heel will be super complicated as one side is normal one side is elevated.

I glued up the back. Next will be the top

The top was also jointed.
The jointed back was give a scrape to see how the good the joint is.
Also the excess glue was scraped away.



Jointed back afte scraping! Nice grain pattern!
