green lumber

[ike]

I have an access to some undried  lumber from a saw mill. I can get all kinds of lumber but I have to air dry it. How long should I let it air dry before using it I have it with air space between the boards. I have some Walnut, oak, and cherry drying for about 7 months. each piece is about 4 ft. long.

Creating the stack with stickers is most important and then having the right place for the stack of lumber.  

 

Here is a article that shows it well

I think the rule of thumb is one year per inch but having a moisture meter is essential.

I have always heard 1 year per inch( thickness) as well.

The sawmill where you got your lumber may have a meter for reading the moisture.

Take a board and ask them to check it

The one year is a "best guess". Again, checking by meter should be done.

Check around. someone has one and it only takes about a minute.
