The dread is looking great Bruce. I am sure Mike will enjoy it. Nice fella by the way, I enjoyed meeting him.

Bruce Sexauer 05-16-2017 06:46 PM

One of my favorite and most satisfying moments is when I close a box and take it off the dish. Here are two sequences of that, one when I reveal the back and then trim it to shape, and the second when I set it on my bench for the first time and then remove it from the dish.

I'd say lots of nice things about Mike but I don't want to make him squirm, and since he is humble in ways I may not be, he probably would too. I do know he is following this thread. He is highly thought of by people I know in these part, including myself.

But this post is about the Ukulele. I glued the fingerboard on this morning and shaped the neck this afternoon after I got back from rehearsing with my band, BLT. We have out first gig of the season this Saturday at Le Chalet Basque in San Rafael, 6 to 8. T can't make it so we'll be a guitar double bass duo. These pics are still at a rough stage, so no premature judgement please.

Koal is slowly becoming more trustworthy as a ShopDog.

Very cool little Uke! Be careful, he might want to play fetch!

I like to think he's looking at me rather than the Uke . . . yesterday he got out the door with my Opti-Vision headpiece w/o me noticing, and today I ordered a new one. Had the last one for over 25 years.

The Dread is going to have flamed maple binding in place of the usual ivoroid. I put in the graft before lunch and leveled when I returned:

Hard to see the flame in the previous pic though it will be easy enough under finish, so here's a lousy photo that shows the flame a bit better:

And what it might have looked like in Ivoroid and EIR:

I suppose this is technically an HD:

Here is the neck brought to six facets and ready to be shaped. Subtle manipulation of these facets are how I control symmetry and profile.

j. Kinnaird 05-19-2017 08:09 PM

Very nice Bruce. I am fond of that headstock/ neck treatment and the rosewood with curly maple accessories is classic looking. Looking forward to seeing that under finish. Also the rosewood headstock overlay with the ebony fingerboard is the way it ought to be done. It looks like a serious music making instrument.

clinchriver 05-20-2017 04:13 AM

Beautiful appointments and execution, is this a "wide" neck? and does that influence your carbon fiber neck reinforcement? Size placement etc?

j. Kinnaird 05-20-2017 05:27 AM

I also applaud the carbon fiber reinforcement with no adjustable truss rod. I'm wondering what your adjustable trussrod philosophy is. Do you ever use them? Do you prefer not to use them or was this particular guitar design suggested by a customer?

iim7V7IM7 05-20-2017 05:33 AM

John, I believe this may be a customer request. I own three of Bruce's guitars. All have single action truss rods. It is still early out West, I expect Bruce will explain in depth...:)

Bruce Sexauer 05-20-2017 10:01 AM

I typically use LMII's TRST single action rod which has proven utterly reliable and consistent re how it responds to turning the adjustment nut. I find double action systems I have used to be finicky and anti-intuitive, and since I know my materials to be properly cured, stable, and chose every piece personally, back bend mitigation (the only possible advantage of the double action rod) simply doesn't come up.

My first few implementations of Carbon reinforcement included an adjustable system as well, but it turned out to be redundant. As long as I know what string tension I'm working with, my set up system has proven adaptable enough. Occasionally I do have to pull the frets and re-dress the fingerboard to get it perfect, and this is why I charge more for the CF system. Also, my arms itch for a day or two after machining the stuff.

This guitar will have a pretty standard 1 3/4 x 2 1/4 strung set up, but CF is in no way dictating this nor limiting my neck size options. My CF bits are made by myself from some 5/32" sheet stock I picked up years ago at an LMII yard sale.

All I know is I took your advice and installed the Lmii double truss in my latest one you saw, MAJOR difference between it and the hotrod, the Lmii is a WAY better rod. Thanks for the advice President Sexauer, you're not in charge for nothin' :up:

edit; I am starting to lean t words the one way rod myself, after REALLY thinking about it, the statistical chances of a neck bending the opposite way of string tension is probably quite rare and most likely a result of extremely bad stewardship. The advantages of weight reduction, being able to have more neck meat under the truss channel, thus being able to carve slimmer necks if desired, and probably less chance of developing a rattle, all are starting to override the "what if some idiot goes guitar playing in a thunderstorm" line of thinking

Bruce Sexauer 05-22-2017 01:41 PM

Mike's D is down to the logo, heel cap, and some more sanding. I expect to put it into finish today or tomorrow morning. It seems a bit heavier than the last few guitars I've made, so I weighed it. Sans tuners, bridge, strings, and finish it's 3 1/4 pounds, which probably isn't heavy at all for a Brazilian guitar. My perception is a bit skewed, I suppose.

Both are lighter than mine (3.5lb), and it's smaller, an LOO. On the other hand, my next lightest guitar is a full pound heavier and it's similar sized, though it does use heavier materials (Macassar Ebony). Funny, if I disregard the National, all the rest of mine are in the 4.5-4.8lb range, except Bruce's - he might say it was exceptional, only I got to say it first.

Sam VanLaningham 05-23-2017 10:17 PM

Bruce thanks for being such a clean thinker and good teacher! I did a birds beak in my second and third guitars using the martin style and they worked fine and all but your more straightforward design IS AWESOME! I just busted one out today on a new build and it worked so much better than the more-angles martin style.

Thank you so much.

Sam

At the moment I am clamping on the headstock verniers, and soon I will have pictures of that progress.


Bruce Sexauer 05-24-2017 11:05 AM

Thanks for the considered comments, Sam.

A couple of weeks ago, Sam sent me some Engelmann violin wedges he cut in his native region of Oregon. It will be a while till I can use it because it is not yet acclimated to my shop, but I did mess with it enough to be able to say it is really beautifully even grained and stiff enough to have every chance of being truly great material. He claims to have no commercial intentions but if this is any indicator of his skill and resources, we should hope he will change his mind.

In other news; I have put the first coat of varnish onto the all "Tree" Uke and it does not disappoint:

I am having trouble illustrating the depth of curl in the Maple. It is really good stuff IMO, yet the camera just wants to look at the Brazilian.

cigarfan 05-24-2017 01:56 PM

Both are beautiful. Don't blame the camera. That BRW is something to look at. Wow! And that "Tree" uke is no slouch either. Very nice Bruce! :up:

iim7V7IM7 05-24-2017 02:57 PM

Some pretty astoundingly beautiful work coming off your bench this week (kudos)...:up:

Bruce Sexauer 05-24-2017 07:52 PM

Now that the other two projects are in the finishing process, I have some time to complete the Pernambuco 000. I spent several hours today hand sanding the well cured varnish with 2000 grit and then buffed out the body:

http://mojoluthier.com/LP17/267P/buffedtop.jpg

http://mojoluthier.com/LP17/267P/buffedback.jpg

Tomorrow I will get to the neck, most likely, and then assemble the two together.

tadol 05-25-2017 09:15 AM

Those may be about the penultimate trio - a perfect combination of outstanding materials and craftsmanship, and I'm sure they'll sound and play at the same level. A incredible braz dread, pernambuco 000, and a Tree uke? Yeah, that'd pretty much do it - although I might throw that pear 0 into the mix, since I'd be down at those crossroads trading in my soul -

ChuckS 05-25-2017 04:37 PM

Bruce,
That Pernambuco 000 looks really special. I hope someday to try your guitars.

tadol 05-28-2017 09:08 AM

Had a chance to see all three of these in person yesterday, and as hard as it may be to believe, they actually look even better in person - Hope I'm nearby when its time to string them up -
