This is the bracing pattern. Seven lousy fans with no closing bars. Big whoop. I copped it from looking at ‘ol masters’ of the 20th century.

The braces are pointed just under the center of the Tenth fret. Why? Because it seems cool.
The cedar top is 2.5 milli from the low transverse brace ( that’s harmonic bar for those of you who speak Romanillos)

Top thickness in the action zone is 2.5 in the middle and around the perimeter it’s 2.0 graduated to the 2.5 center area over a distance of 60 mm from edge to center.

So there’s a swath of graduation from 2.0 to 2.5 from the edge for 60 mm. Like a horseshoe shape.

Here’s the closed up Cedar top around October 9th.

Braced up spruce top from October 12th

The top is fairly thick, but I forgot the graduation off hand…

It follows the same scheme as the cedar with meaty center and a perimeter graduation down to 2.0 milli.

Then the braces begin the slope from full height to the low end in a way that correlates to the graduation areas.
So as the braces taper down to nothing, the graduation from full center thickness also follows the taper of the braces.

The braces get thinner in the same region the top is graduated thinner.

The Cedar with Sakura back and Macassar sides ( upper photo) is the sister to the one I sent out last month with the same back and sides. (Lower photo) I wish I could have been able to build them as a pair, but my list schedule didn’t allow for it.

This is Orangie, she joined the shop in July. She’s about six years old and used to live with an older couple about three blocks away. The couple died and she was left in the street for a few months. She came to my door and couldn’t move much, very sick. She followed me around outside for a day. Then we took her to the vet and got her checked out. She had anemia and respiratory problems. I fed her fresh fish and good food until she began to put on weight. She’s doing better now and likes to hang out when I work, often getting in the way.

She’s not a big cat, but has gained popularity with my friends on Instagram because she poops out huge turds. In the beginning she was constipated and I thought she would die, but on the forth day she mounted the litter box and pooped out a gargantuan turd. I began to think she would make it.

Those macassar sides are still outstanding. Looks like another great one similar to the other you recently finished.




RobF -> RE: Building two classicals on a deadline- will I make it? (Oct. 15 2022 23:11:43)

The rosette on the cedar topped guitar is a perfect match to the macassar sides. Also, the back’s center stripe marries nicely with the neck lamination and visually pulls it all together. Very attractive.

Question: is the heel a different genus of wood from the rest of the neck? I’ve seen old Ramirez guitars that sure look like they have cedro necks with mahogany heels, so I’m wondering if you’re doing something similar. Or is it just the grain direction and lighting that’s making it look like different colours of cedro in the picture? It’s not a trick question, lol, I was actually taught that cedro/mahogany is a valid combination.

Another question: I like using one piece diagonally slanted grain heels a lot, but I’m not married to any one style - stacked, single block vertical or slanted grain - it’s all good, although I like the look of single block slanted the most. But last time I was in Spain a maker dumped all over me for not using a stacked heel. I was kind of astounded, actually. Do you have any preferences?

Your cat’s a sweetheart, BTW.

Wonderful stuff! I struggle with too many words these days due to time constraints, and mental capacity, so pictures are right up my street! Thanks for posting. Yeah I had to check the dates for a second as that maccasar sides guitar was a bit of de ja vu. But I see it's a sister guitar!

And I love the cat and its back story! Thanks for sharing that. 👌




estebanana -> RE: Building two classicals on a deadline- will I make it? (Oct. 16 2022 10:36:35)

I don’t know if the heel stack wood is a different genus, but it’s a different species than the neck. 😂

The neck is cedrella odorata - genus Cedrela you know Cuban Cedar

The heel is something I forgot to name of, I’ll remember.

I’m not worried if it’s a stacked heel or a single piece block. I don’t have time to dither over that. The single block is nice if you can get it, but I don’t see why anyone would give you trouble over using it. It wastes a lot of wood and I’m such an enviro- weenie that that bothers me.

Anything strong enough, the correct weight and not prone to split is fair for heels. Mixing and matching within reason is fair game.




RobF -> RE: Building two classicals on a deadline- will I make it? (Oct. 16 2022 12:19:09)

Oh man. I looked up “genus” on Wikipedia and decided it would be easier to just stop using the word than reading through the article to figure out how to use it correctly, lol.

Thanks for your thoughts on the heel blocks. I cut my neck wood out of larger 12/4 boards so generally I can grab chunks off the ends to purpose for blocks. Other than that, it appears we’re pretty much on the same page. Good to know. Thanks [:)]




estebanana -> RE: Building two classicals on a deadline- will I make it? (Oct. 16 2022 14:24:45)

The heel wood I’ve been using for a while is called Mersawa. It’s from Malaysia. It’s used in Japan for door frames of custom shoji doors.



Taxonomic classification for Luthiers:

You don’t have to worry about Genus and Species, it’s Pylum, Class and Family that matters:

Is it in the plant world? Phylum check

Is it wood? Class check

Is it a wood guitar makers will argue about? Family check

Genus and Species? Irrelevant, as long as you argue about it.

Some of us have come close to leaving the soundboard-to-solera clamp in place while gluing the back on--and some have actually done it. I hope you won't leave your cat inside the soundbox by mistake....




Stu -> RE: Building two classicals on a deadline- will I make it? (Oct. 18 2022 7:22:36)

yeah, I have a 50/50 hit rate with such a blunder.

Binder clips almost seem made for this job. I just wish there were some very narrow ones with the same depth.

RobF -> RE: Building two classicals on a deadline- will I make it? (Oct. 20 2022 13:19:17)

I find the smaller sized ones work very well, too. I think they’re about 20mm wide and they fit snugly over the lining (better fit, actually). I can post a picture, if you want.




estebanana -> RE: Building two classicals on a deadline- will I make it? (Oct. 20 2022 15:17:24)

I think these are 2 centimeter clips, but let’s see let’s see the ones you’re using.




RobF -> RE: Building two classicals on a deadline- will I make it? (Oct. 20 2022 16:17:33)

I just measured the small ones at 20mm width and the large at ~35mm. I tend to use the large ones for general use and clamping purfling strips to the bottom edge of binding and the small ones for clamping the lining. Here’s a photo of the small ones in use, they snug down right onto the top of the liner:

I’d like to request a close up of the green tape.

Lol. One says “Remove before back glue” and the other “Do Not Leave In!” [:D]




estebanana -> RE: Building two classicals on a deadline- will I make it? (Oct. 26 2022 5:04:58)

Label action, not libelous action 😂

Well then, two guitars with backs on and waiting for binding and boards. Instead of pushing one ahead I wanted them both to get binding at the same time. While one is drying I can fit the binding on the other.

Anyway

Like I’ve said I’m not a rosewood guy first and foremost. I used to work in a vegan restaurant even though I’m not a vegan, I’m a voracious omnivore. Mostly vegetables and fish. But when I worked in the vegan kitchen I came to respect people who wanted to eat a vegan diet. After work I’d often go out with one of the co owners to get a a burger or pizza. One owner was vegan, the other was not and they got along well enough to have a restaurant together for 8 years.

So my offerings of ‘non meaty’ woods is like a vegan option in a meat heavy market place, but of course I’m flexible and offer rosewoods, just not wall to wall rosewood to the exclusion of all other woody menu items. My restaurant of backs and sides averages about 50/50 or 40/60 with non rosewood plates being the majority of woods served. People should be offered the foods they want, but as the chef I also push my own tastes, because I’m the mothetfucking head chef in my restaurant. 😂

This rosewood, I think, is the kind that’s similar to Indian, but comes from Cambodia or Thailand. But oddly the smell when it’s scraped reminds me of Brazilian, but I don’t think think it’s Brazilian.

It’s mystery meat.

So they are built into boxes, now they have to function and look pretty.

The cedar top with the cherry back is the third instrument this year that I’ve built with Sakura ~ in August I finished and shipped out this nifty Irish Bouzouki to a customer in New Mexico US of A
