Post subject:  Multilayer bridges?

Hello everyone, quick question.

Structurally, is it safe to build a multilayer (laminated?) bridge like the drawing (profile view) below?

Would there be any major impact on tone? The woods would be ebony and maple, and a contrasting wood in the middle, maybe cocobolo. Thanks for any input guys.

Glue is always stronger than wood, for sure. I don't know if you should cross the grain direction... not sure.
And from an acoustic view, i don't know the suitability of a laminated bridge.

Our buddy Charles Fox also makes laminated bridges. I tried it on one guitar (an MJ) and it didn't seem to sound any different from normal to me. I say go for it.

This is a highly arguable and controversial statement, to say the least…

Agree with Laurent. Based on what (either way)?

Having never built a lam bridge or for that matter hearing one, I won't get into that argument if the is one.

As far as tone/sound/volume or ehatever, I am thinking it would depend on ayers and thickness of lam's and layers of an how much of adhesives used.

My first was a laminated bridge, an ebony/cherry/ebony. I liked it visually and think the guitar tone was very good. I did not cross grain the laminates, and used titebond III. After a few years now (I don't see it often) I am told you can feel the glue lines. I assume the cherry is less stable and shrinks a bit more in the winter.

Danny, I would assume cherry to be more stable than any ebony. OTOH TBIII is known to cold creep.
