[QUOTE=RussellR] Hi Dave

I've seen a three piece X Brace done on a Seagul Guitar, I think someone posted it here, but from memory I don't think it was capped.[/QUOTE]

Russell,

It must have sounded terrible then

Thanks everyone for this great thread. I have learned a ton and it has me thinking....which is probably not good.

Of course everytime I see the thread title I keep thinking (in my best gangsta rap voice), "I'm gonna bust a cap in your x-brace!"

Seaguls are a touch hard to bend as they peck like crazy when you try to get them between the slats, although it helps if you rap the bill in Kraft Paper

Do you think they sound better when they wear a cap ?

LMAO here Russ!

[QUOTE=Dave White]

Although the soundboard is bridging the gap, there are the two edges of the brace halves glued to it. [/QUOTE]

This is the same situation with the notch-up brace in a normal lap joint, right?

[QUOTE=ToddStock] I think you've got it. The one issue with the butted X joint is how the soundboard will carry the compressive load on the notched brace, which is an issue only because of grain orientation.

[/QUOTE]

Isn't this the same issue with the notch-up brace in a normal lap-joint X, whose notch is bridged by the soundboard, i.e. the soundboard is carrying the compressive load? If you're suggesting that this would more of an issue with the butted-and-capped brace in our hypothetical model, I'm not following you.

BTW, thanks for the explanation of "stress risers". That was pretty much what I figured it meant, but your explanation was very helpful in clarifying it for me. I'm still having a bit of a hard time getting my mind around the case that Al was discussing above - how any slight irregularities in holes drilled through a brace would create stress risers. Hmmmm....
