It's not a cigar box guitar, but.....

Postby mumaharps » Mon Apr 27, 2015 3:50 pm

I have been inspired to make some thin ukuleles. The inspiration came from an instrument made in Quebec by the Seagull Guitar company called the Merlin. It is a dulcimer in sort of a guitar shape. What was unique acoustically about it was that it's overall thickness in only 1 inch.

So the Aspire connection is that I have used a "model" generously provided by Carveone of the head stock of his cigar box guitar. A slight modification was to angle it downwards with the tilt tool. Used vectors for the rest of the tool paths which included profiling and pocketing. I have finished a tenor sized uke and am working on some more which includes a couple of soprano sized Ukes. The stock was finished to one inch. I didn't opt for two sided machining as I wanted to shape the neck by hand. The photos show where I'm at so far. The banding on the sides of the finished tenor are a result of needing to cover mistakes.

Thicker sound box walls so no lining was used for gluing the sound board.

That looks great!

I like the sound hole treatment a lot. Anything you can use the files for just inspires me that much more. :)

mumaharps,

Very nice! :)
You just inspired one of my next projects.
Being I make my CBG bodies from a solid epoxy laminated block this is right in line. Being laminated I can get the wall thickness around 3/16- 1/4
The last one was yellowheart and the sides were a tad over 3/16 w/ top epoxied directly to body. Sounds very crisp w/ light acoustic strings
I'm thinking 1/4" thick lams (1 1/2 total) of purple heart or bloodwood and hard maple for the body and curly maple for the top.
Can I get a ukulele from a true 8" wide blank? Do you have basis measurements or a good link? including fret scale, string sizes etc.

Thanks,
Glenn

Hi Glen,

Here is a link for a pdf of a soprano Ukulele

Fret calculators are on the net -- one that I have used is this

I calculated fret spacing after every thing was together. That way I didn't have to worry about total accuracy during assembly. Just me being paranoid about fret positions.

Thanks for the quick reply!
Looks like an 8" wide blank will work perfect and with a scale length of approx. 13.5, they are smaller than I realized.

I will never sing like "IZ" (did, sad) but maybe I can play like him :)

Yah, well.... who will sing like Iz.

As to scale length When I've made a soprano before I thought the scale was a little short. I much liked the results of the tenor better. I am making the current soranos with a 14" scale.

Good luck...
