I was looking around to see what was the hardest wood types, what was the softest wood types, what was the hardness of the wood I had available and although I didn’t find all the woods in the world, I did find this and it seemed to be the biggest selection and largest variety. If anybody knows of more, please let me know.
Thanks.

Thanks for posting Obi – this is really usefull for me. I have been using the “cherry, brazilian Jatoba 12.5 kn, 2820 lbs” on some projects, I knew it was hard, but not as hard as is described in the document. At least that explains why so many tools became damaged so quickly

It’s funny that you should mention that. I just posted something about the hardness of differents woods.

http://lumberjocks.com/projects/5175

It was concerning the hardness of the sole of a plane I made.

lignum Vitae is the hardest that I know of at 4500
Balsa is so soft it doesn’t even get a rating on the chart.

Gary, funny you should mention me mentioning it because you mentioned something about it too.
And although Hickory isn’t the hardest available it probably is one of the hardest domestic woods over here, and I’ve done so many projects out of Hickory that one of my router bits starts whimpering whenever i look at it.

Brazillian Cherry is what I make drumsticks out of and give a lifetime guarantee. But then I charge $20.00 a pair.

I was wondering about the numbers of bamboo into this scale…..and must be somewhere, because it is being extensinely used as a flooring material.

I know epi is so dense it sinks in water but I don’t know were it falls on the hardness scale
