Just a question I am having difficulty finding Spanish cedar for necks can I use African mahogany with graphite reinforcement rod?
Thanks
Blake

Don't see why not. I haven't used African, though, but I assume, if it's stable, it would be fine.

Blake,
How timely. I'm hoping the more experienced guys will reply with "yes". I just glued up 4 necks, 2 are African mahogany (foreground) and 2 are Spanish cedar. I'm not planning on reinforcing these in any way. They are for classicals.

I used it many times without any graphite reinforcement. No issue at all.

The only thing you want to watch out for is that some rare boards are quite dense, thus making a guitar that would be neck heavy. Usually these boards will be darker as well. The paler stuff is usually quite similar in density than Spanish cedar.

As with anything, depends on the individual piece of wood, but I've built quite a few guitars with african mahogany (Khaya), electric and steel-string acoustic. All have CF rods in them, though I don't think any of them really, really needed it.

That's what Hauser the first used.

It has some real twist to it.
That's what helps to keep it stable & strong.
It can be very dense so try to get the most lite pieces you can.

You mean interlocking grain, right? Never seen any of the many species sold as African Mahogany with one way twist.

Right Kent!
I have some that was cut in the 1920s!
some twist-very dark color.
Heavy as all hell!
The interlocking grain can make it difficult to carve.
But all Hog wood can be that!

I'm not sure what is meant by interlocking grain. Does anyone have a picture they can post?
Thanks, Wendy

Hi Wendy,

Whenever you see 'stripes' or 'ribbons' on a board of any given wood specie, that means interlocking grain. One stripe shows the grain going in one direction, and the stripe beside it shows the grain in the opposite direction (thus reflecting the light differently).

Here is a picture of ribbon african mahogany that shows this quite clearly:
