Is this one going to have your signature burst too?

Hi Maks - yes we will warm this one up with some bursts too. Again, real subtle, but very effective. I also forgot to mention that I will be doing the dual engineered sound ports in the description above.

Were also discussing the inlay too. It won't be quite this intense though;)

More photos later today.

rosette
 
Here are a few pics of the rosette. The outer ring will be complete as soon as I get more abalone in this week.

Of course I did not originate this type of design, but here is our take on it, and the one going in this guitar.

I am really happy with the colors in this rosette and how they look against the sinker redwood. My son put this together.

progress photos the neck
 
You've seen it all before :-). Here is how I do it. I plow the truss rod with this jig. Then I attach the fingerboard overhang tab, then I rout the CF rods in. That way everything is stiffened and "tied" together. My necks are adjustable unless otherwise requested.

The graphite rods really help fight the compression that the strings exert on the neck. If you use the allied lutherie truss rod, a good way to make the top 'flat' bar also fight against this compression, is to put a little wood tab above the adjusting nut - then glue the spline over the bar and out onto this 'tab' that goes over the nut. Don't leave it "open", or stop the wood spline where the rod ends. This "traps" the top bar and when the strings start to compress the neck, the rod will bear against that little piece of wood (conversely that the headstock overlay is laminated over also on the face side), and will act to further resist this compression. Makes for stiff necks. Make sense? I might have a pic if someone doesn't get what I'm saying.

Thanks Steve, I appreciate the compliment. I'll have more photos of the back and back bracing up today. I'm working on the sides now and will have them up in a day or two.

Have a great day.

Kevin.

back bracing and sides
 
Here is my back bracing scheme on this EuphoricMojo. I have found that this works well with this shape.

The sides will pop a little more after I get them sanded down. So far its coming along really well.

I'm trying to get the inside of this one looking really clean.

I've got the sides bent and should have some pics of those up soon.

Have a good day.

Thanks Steve - I am sure going to 'follow this thread through' to the guitars completion with a picture of the owner playing it.

I am also starting another thread, soon, of my FIRST SJ guitar. I've been designing it for some time. No big secrets or anything like that, just something I'll want to look at for a while. The look/design has to work for me.

Anyway, it will be serial #1 and I'm going to do some cool things on it to make it "memorable". And use some nice wood combinations. Please keep an eye out for that thread too!

Also - I guess I mentioned my dual engineered sound ports but never posted a pic. Here are a couple pics of their look/layout. They are a lot of extra work, but some things are worth the extra time. You know what I mean?

Those soundports are absolute works of art (as is the rest of that guitar). I've never seen anything quite like them.

Nemoman 02-20-2013 10:42 AM

+1 on the soundports. Those are truly unique and beautiful...

mikealpine 02-20-2013 01:09 PM

Kevin,

The look of the sound ports is fantastic and different. Are there any other advantages in crafting the ports this way?

Thanks,
Mike

Thanks for the compliments MBE & NEMOMAN on the sound holes ports.

Mike - I never liked the open hole look on the side of the guitar - it looked unfinished to me, so I decided to "tune" the box and engineer out the holes. A few years ago I was only putting one hole back by the bevel - the rear one. I figured I could somewhat "triangulate" the sound to the player if I added that second one up front...not stereo, nothing like that, but just more of a 'directional' sound. I feel like it opens up some of the higher frequencies to the players ear. It allows them to hear a different "perspective" of the guitar.

Hope that doesn't sound too mumbo jumbo - in short, to allow the player more chance to hear the higher frequencies when he/she is playing.

Have a great day.

Kevin.

more pics tomorrow.

abalone binding/headstock
 
I also mentioned that I would be doing the abalone binding on this guitar. So here is a headstock picture of another guitar with the purflings, abalone and bindings. This is a similar scheme I'll be doing on this redwood/koa Mojo.
