Prepare for Close Box

The side braces are ready to be glued.
In the preparation of the side braes, my saw teeth was destroyed.
To glue the side braces, they need to be inlet into the lining or peones itself.
This is to prevent the side braces from exerting weakness on the sides as it is basically a cross brace on the sides.
Luckily this is ABW which is a very stable wood.

Next is to prepare the backing for the sound port.
One thing have to be sure is not to mess up the position of the sound port.
It should be done at the side facing the player i.e. bass side.
Although one can argue to open 2 holes, but more sound port will cause degration to the low response of the sound.
So need to limit how many and size of sound port open.

The veneers were glued to the back of the position of the sides where the port will be opened.
A curved caul was made to ensure the veneers are clamp properly.

Next will be the cutting of the sound port itself.
The commissioner of the guitar prefers to have a star shape sound port
So but the problem of having a star shape is that it's not symmetrical.
So there need to be some form of orientation.
So I was deliberating the orientation of facing the player or straight with respect to the guitar.
Finally decision was to take reference to the guitar.

The hole was cut and file to shape nicely.

I glued the tornavoz to the top also.

Added one more side brace at the end block to increase the total side brace weight to be about 400g

New workbench!

20200716
I ordered a new workbench and it finally arrived after 1 month of sea shipping.
I spend about 2 hours assembling the workbench and it's quite easy to assemble it.
Weight is not that heavy which is good for me since I am the only person around to carry it.
I assemble the base with cabinet first and then leave the top separate.
In the next good half of the day I spend the time to clean up the workshop to make space for this new workbench.
Some thinking was done to see how better to organise the workshop.
Finally I was able to carry in the base and install the top on the spot.
With the new workbench I need to figure out how best to clamp the work pieces.
The table isnt of uniform thickness; so I need a caul at the below surface in order for my cam clamp to work properly.
Also there is limited space due to the cabinet so the F-clamp doesnt work. I had to make some dog hole clamps which work fine

After several weeks of playing around I finally figure out how best to make use of the workbench.
Normal workbench caters for thicker pieces of wood to work with while guitar making make use of thinner pieces of wood.
So there need to be some modification of the workbench in order to use it efficiently.
But I was happy to have some extra space to work with.
Especially now I dont need to disassemble my go-bar deck after use.
But my old workbench 's free table top space was fill up pretty quickly.

Assemble the guitar

20200219 - 26
One of the most exciting stage is the assembly of the guitar.
This is because you get to see the guitar taking shape
But before the assembly process starts, quite a fair bit of things need to be prepared.

First I need to fit the sides to the top shape.
This is because of the elevated fingerboard design.
The upper bout actually dips down and the sides need to conform to the shape.
Once the sides is fitted properly, I also check for squareness of the sides to the top.

Once the sides is fitted nicely, I began to work on the neck heel block too.
I needed to cut the side slots and fit the wedges accordingly.
Once fitted nicely I also drilled alignment hole for the top and neck and the heel block.
This will ensure the neck is centred properly with the guitar body.

Also I cut the peones block enough for filling the rim of the guitar.

All is set for the assembly and I began the process.
First I glue the heel block onto the top.
This part is crucial in making sure the alignment of the centre line is done properly.
Otherwise the neck will appear crooked to the guitar body.
However this for this elevated neck build, only the heel block is glued rather than the whole neck.

Next step is to fit the wedges into the side slots.
This will lock the sides in place onto the neck heel block.
The actual gluing is done later.
Next I glued the end block to the sides and onto the top.
Then I began to glue the peones blocks onto the sides.
The blocks uses is mopani blocks which is a dense wood.
Having a dense wood at the border of top and sides is a good thing for the sound.
I alternate the blocks with the usual lighter density wood.
Those junctions with the LTB and UTB and end block I try to fill in as much as possible.
Then I cut special blocks to fully fill the gaps.

All done

Next I shape the back rim using block plane and the radius jig reference.
The actual fine tuning will be done with all the back braces in.
Next I prepared the side braces and the 1st 2 back braces using my African Black wood stock.
This is the first guitar using the ABW as a back brace mainly to focus the back vibrations onto the lower bout.

The side braces are glued next.
The side braces are hard to prepared due to the hardness of ABW.
My saws teeth were ruined due to it.
The 1st 2 sets of side braces needed to be fit to the curved UTB and LTB profile.
These took some time as the cross section profile of the UTB and LTB is like a bullet shape.

Once the side braces are ready, I began to glue them to the sides.
The first 3 sets of side braces are glued which also act as support for the LTB and UTB as well as the 3 back braces.
My preference is for the 2 back braces to be aligned with the 2 traverse braces of the top.
This creates a sort of gate looks within the guitar.

Once these main side braces are done the back braces are cut to length and the back curvature are shaped into the back braces.
Further shaping is done with the curve rule to ensure the back is smooth thru'out.

Glue the 3rd set of side braces for the 3rd brace support.

Checking the side braces fit with the UTB and LTB and back braces fit.

Checking the back curvature

All 3 back braces prepared.

The back lining is glue to back rim and shaped together with the back braces to form the overall back curvature.
The curve must be smooth otherwise the back will have unnatural dip somewhere.
Some makers uses radius dish to make the rim confirm to the back radius dish.
For me I use more of natural curvature of a flexible rule as a guide to fine tune the radius.

Once the rims is prepared the sides braces are glued too.
