I am searching for a reliable online wood property table that cover as many species relevant to bowyery as possible. I am looking for not only specific gravities but for modulus of elasticity and modulus of rupture. Metric would be nice, but converting from psi to MPa is a small detail.
I have been able to find a few things, but nothing that covers all the species I want, or all the values I want. So list as many as you know as long as you know them to be accurate, because I probably won't find everything I want all in one place.
Also remember to add a space somewhere in the web address so that it won't be a direct link. We don't want to rip off the magazine advertisers.

check out tim bakers bow wood chart, it's got a lot listed

here's a link to the list

Yep already checked that one out. But it only lists SG.

You'll have to just google. I've seen the data for just a about every wood that could be sourced for bowmaking but not all in one page.
Although this one comes close. http://www.conradlumberco.com/pdfs/ch4-Mechanical-Properties-of-Wood.pdf

A lot of lumber companies will post a complete data sheet on their websites. Generally all you need to do is type in the name of a wood species followed by the word 'properties'.

most data like this is just a good place to find averages. The stave you hold in your hand may well be an exception.
Much of Tim Bakers testing and research as seen in The Traditional Bowyers Bibles is available at P.P.

Thanks guys. I appreciate the assist.

The guy also wrote an article about the characteristics of wood WRT bowmaking.

I have a table on my PC. It lists Compression in FSPL, MCS. Also list for Tension, Shear and static bending.
I can't post it here the file is in JPG tried to convert but much to large at 227k.
Let me know I'll PM it to you.................

I echo this one! Chapter four of the Wood Handbook is absolutely outstanding literature. Yes, it's lengthy and can be overwhelming in the terminology, but it is really valuable.
