Naturally it's to glue them in.
Before that I prepared the donut (sound hole reinforcement).
I had a dry run 1st before doing the actual gluing and keep all the things I need at hand.
Luckily I did the dry run as I realised I had adjusted the upper deck of the go-bar deck upwards to cater for the gluing of the back aka closing box.
So I had to adjust it down. After that I recall that I had to work inside out.
The dry run was done and I began to start.
The HHG was at hand I did everything in about 15 minutes.
That was pretty fast.
Shooting and jointing the donut.
Cutting out the donut. The inner circle is same as sounhole. Some maker cut the soundhole after the donut is glued. I prefer to do them separately for better alignment

Ensure it conforms to the doming

All glued
After the gluing dried, I began to carve the brace.
I use the thumb plane and chisel.
I reduce the height of the brace to 3mm as per Torres.
And then trim the length-wise profile to a gradual sloping profile towards the ends.
After the go-bars are removed.

After the fan braces were done, I began to work on the traverse braces.
First of all is fitting the large Bouchet brace over the fan braces.
I fit the bottom of the Bouchet brace by marking the pencil over the solera.
Then I shoot the bottom of the brace according to the line drawn.
After that I mark the fan brace position and measure the height of the braces and chisel the notches in the Bouchet brace.
I had to adjust some of the notches to fit.
Finally all was set but at the bass end the base of the brace didn't fit as well.
I had to shoot further to adjust until they fits.
I use the go-bars to clamp and check the fitting.

It's time to glue up the braces.
This round I glued up the closing brace, Bouchet brace, and 2 side braces (UB)
The procedure are about the same except I need not use the ruler.
The existing brace will prevent too much skidding around of the brace.

After the glue dried I began to carve the braces.
For the side brace, I make the brace 1mm taller, the bass side is 3mm, treble side is 4mm.
The closing brace is 3mm tall as per Torres.
The bouchet bar is the one that I have no experience with...
So far after I shape it with the treble side taller, I tapped the board and it felt overly stiff.
Think I will have to thin them more.
Meanwhile I probably do tap tone recording and analyse how to thin them.

Check the weight so far: 180.7g
Full brace with UTB LTB and treble bar, let check the weight again.
Oops... overweight. Time for some diet; target weight is under 200g preferably under 190g region
Saw slots in the UTB for making the opening aperture
Chisel away those slots and then file them smooth

I am quite lucky to have a mentor to guide me whenever I have doubts.
I asked Alexandru Marian who is an expert in making Torres and Bouchet style guitars on what are the dimensions of the Bouchet brace.
He commented my brace is too big and too long.
And so I reduce the height and length of the Bouchet brace.
Now it looks much nicer.
The weight is 202g almost there!
If you ever look for a Bouchet style or Torres style guitar, look for Alex, you won't be disappointed in the guitar.
And good thing now is his guitars are undervalued now == value for money.
When I save enough I will order one from him too :)
Carving the Bouchet brace
Almost done probably will refine more.

Next I glued on the traverse braces.
Nothing new but using the same solera and go-bar deck.

The bracing is done, after cutting off the excess ends of the traverse braces, the final weight was reduced to 197g.
Not much but at least it's less than 200g.
I would have prefered it to be in the 180s region though.
Here are some pics of the final bracing.

In order to reduce the weight I trim the UTB a bit and the reduce the plantilla to actual size with not much overhang.
I also shape and thin the soundhole donut to reduce the weight.
Finally after all the sanding and trimming I am able to reduce to 189.5 under 190g.
My previous top was 188 I believe, at least I am to get it under 190g.
I really like the look of the donut ring.
