What would walnut and cherry weigh after being air dried for 3 years?

Hey James,

Here's a chart I found with green and kiln dried weights. Air dried (or any long term stored timber) would weigh a bit more than the kiln dried weight with it achieved EMC. I think this should be a fair guide though,

(scroll down a ways, I couldn't see to bring the table up!)

A ton of wood would weigh 2000 pounds.

Do you mean how much lighter would/should/could it be after air drying from solid green wet to... to... to.... who knows what, depending on how/where it has been kept for 3 years?

There are probably charts/tables online that have wood densities, specific gravities and cubic foot weights. Maybe a moisture meter is in order here.

Sorry I can't help more. Todd.

Todd,

I always figured a ton of Texas lumber would weigh more than 2000 pounds! :D
