Official Luthiers Forum!

G'day everyone.
Thank You for very interesting forum. I am a beginner guitarbuilder, and this my first post here.
I have several questions:
For making of the 7-string guitar I want to use Makassar Ebony and curly Redwood...
As this woods together for compatibility? What sound I can expect (approximately for tap tone, etc...)?
What optimum thickness for back and sides possible to do?

Thanks.

Excuse me for English, I from other country...

Hi

I have only used it once on my first and it was a great - I used German Spruce for the top so cant comment on your combination, but it gave a wonderful bass response - really pleased with teh tone, probably down to the density of the wood. Works quite well, but blunts tools VERY quiclkly which makes for plenty of sharpening practice!

Not sure how to link a topic but if you search my early posts you will find some pics.

Hi Sergy and welcome to the OLF!

Curly Redwood is not a very stable wood and even though I have built with it before with no issues I would be reluctant to do so again. It can be very brittle and has lots of runout that can be problematic.

Here's a pic of my curly Redwood guitar:



Welcome aboard!

Thank you for answers

Filippo, I dreamt to make such guitar for a long time... I speak about Russian seven-string guitar.
I have built not much, only four classical guitars (Also there were many repairs),
but Makassar Ebony and curly Redwood did not use, therefore I have questions...
Woodworking I done, the back is glued, processed by sandpaper.
Back - 2,9 mm, sides - 2,4 mm, soundboard - 3,0 mm. What you say about thickness?

G'day all
My work is finished.
Some photos of this guitar:

Looks nice!
The back and sides thicknesses seem very high to me, I would have probably made the sides 1.8 and the back 2.2. But the top at 3 is probably fine.

Stunning guitar Sergy, well done.

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Amazing work and wood choice, particularly like the carved bridge and end inlay!

Thickness for:
sides - 1,8 mm
back - 2,5 mm, to edges - 2,3
soundboard - 3 mm, to edges - 2,5

Yes, it so. Only a redwood problem... It is necessary to be careful.
