Tnx Bruce, for the explanation of the upper winged brace . Sounds like a twofer., and your correct abt the adi top, , that is, trying to tone it down to get that flamenco sound . Have a bit of adi, it seems very stiff longtitudinaly, I have yet to use it. Are you going to make a sound sample ?? Thank you once again! .

Nice looking work with the peones. When I have used them they have never looked so uniform and cleanly done.

Being hand split, peone are never quite the same as each other, but being the same height helps. Spacing them the same also helps. It it possible the control the stiffness of the top to side connection somewhat by how closely the peone are spaced.

The back will likely go on before the day is done. It is in the go-bar deck having "marriage strips" glued on.

Hi Bruce. I've seen some of your SS builds but this is the first nylon string.
I just noticed there's no bridge plate, is this typical for your NS instruments ??

What would be the purpose of a bridge plate on a nylon stringed guitar?

Today I rough-carved the slots in the headstock and put on the first 2 quarters of the binding.

Sorry, mix-up in terminology. Many of the drawings I've seen for classical/flamenco instruments have a bridge pad. The fan braces are notched to fit over it.

By whatever name, I see no purpose, and I do see weight where I wouldn't like to have it. I use a full caul under the top that matches the bridge footprint, so there is no need there. Most classical makers spend a lot of effort getting the bridge weight exactly whatever, and then there are several grams of what-ever-it's-called added to the weight: Seems counter productive. The bridge is already the most powerful brace on the top, and surely mirroring it on the inside is unnecessary. If not, I'd like to hear about it.

That’s interesting. I’ve wondered about the bridge plate for ukulele. I think I’ll skip it next one, see how it changes things. :)

Thanks for the tip.

Some makers use the bridge plate on nylon instruments to "balance the construction" similar to plywood, and some leave it out because they feel it - adds - stresses. Some of the best makers have used it , and some of the best makers have left it out. Romanillos said he has used it and said he has left it out. I guess he goes both ways. pizza

Today is my Daughter's Birthday Celebration, and I will take the day off . . . almost. The Madrone/Adi "Flamenco" is final sanding away from finish. Fresh pics:

Bruce, Are you using two carbon fiber rods on the neck? Do you use that on all guitars, or just the nylon strung ones?

How did you create the dark lines between the back seams? They look too thin to be veneer, but too obvious to be unintentional.

Nice Idea, I did something sort of similar but went with woods that border the Pacific Ocean, Madrone (called Arbutus up here) and Koa for the top.. Turned out nice.

I'm looking forward to watching this. Having lived in the Northwest most of my life, madrone trees are one my favorites. I have two madrone back an side sets that also come from northern California. The tree was so big that the back plates are big enough to make two-piece backs. My plan is to build two steel string guitars using only West Coast woods, with the exception of the fretboard (unless I can find a suitable native wood for that).

What wood do you plan to use for the top?

I offer it as an option on SS, but it is standard on Nylon.

The lines are .012" black fiber.

I did not realize Madrone and Arbutus are the same thing.

Yup, the Pacific madrone is one of several arbutuses (arbuti ... arbutussaria ... arbutilicious?) or whatever the plural might be.

I've got 6 coats of oil varnish on this guitar, and that's either one or two to go.

Probably bug you with some more pics in about a month, when I expect to string her.
