G'day all,
 
A friend of myne has said that he has a few big pieces and a stump of a Dawn Redwood (Metasequoia Glyplostrobaides) tree at his house, and asked if I wanted any for luthery work. I've been trying to work out if the wood is any good for a soundboard, and was wondering if anyone knows anything about it. I've done some searching on the net, and can only find that Californian Redwood is commonly used as a soundboard material, but no specific info about the use of Dawn Redwood.
 
The two different Redwood species seem a fair bit different. The Dawn Redwood is very very light (density of about 260 kg/m3 or 16 lb/ft3) and has a Modulus of Elasticity of 5500 Mpa or 798000 psi. It appears like a very tight grained pine but lighter, with quarter sawn grain spacing of about 10 grains per inch.
 
Does anyone have any ideas or experience with this timber as a tonewood?
 
Thanks,
Matt

Welcome Matt,

Don't know anything about it as a tonewood, but it's one of my favorite trees. Here's the story of the one I walked by every day while attending the University of Oregon:

UO Dawn Redwood

I suspect it could work out nicely as a tonewood. If there is any chance of buying or trading for a piece to try as tonewood, I would LOVE the opportunity!

Cheers,
-Dave

Yeah Jim, I think they tend to be skinny, especially since they have only been reintroduced to the rest of the world in the last 60 years or so. By my math the tree here at the University, being 10 feet in circumference and 55 years old, should have growth rings at an average of about 2.89 per inch. Not great, even if it's not a good measure of tonewood quality. Regardless, I'd be interested in trying it out, if for no other reason, just for sentimentality.

-Dave
