I see the specs on most moisture meters show the bottom end of the range to be 6%. How dry does wood get? Is it below 6% much of the time? If it does get that low, does it come back up aclimatizng to coastal climates?

It will aclimatise eventually. Wood we used in the Philippines usually ended up at 18 to20% after kiln drying if left alone. Maybe you gotta live in a desert to get 6%!

Hmmm, I suppose it might not be that low here on the left coast of the US either then. I’ve never thought much about it before. I have always used wood kknown to be dry.

Kiln dried wood does adbsorb ambient moisture while being worked and even with the stain is applied at the exposed surface and open grain. Tennessee and Georgia usually has high humidity during the summer time and it will effect the project.
Attached is a good article from the University of Kentucky
http://www.ca.uky.edu/agc/pubs/for/for55/for55.htm
Also a kiln opreator handbook

I use a small kiln to keep my project dry while working rifle stocks due to the warpage of the wood can impact the accuracy of the rifle.

United States forresty division put out a phamplet also and it shows the various drying variations around the nation due to the moisture content in the air versus wood and drying allowances.

If you’re in Death Valley, the wood will get down to 2% humidity or less. It just seems to disintegrate into splinters, which is why, I imagine, that the picnic tables are cast concrete or aluminum instead of wood.

Thanks Minuteman, those links pretty well answer the question.

I dunno guys. I found that a piece of walnut I’ve been saving turned into a pile of sawdust…and my son also has a new door threshhold. Walnut of all things. I wonder which big box store he got that from?

I do live in the desert and if you want to see dry wood… well, I seldom can buy wood from HD or Lowes in the summer time because the stores are air conditioned and as soon as I take the wood to my truck it is already drying; checks, wraps, cups and everything else you can imagine. Wood left outside for the summer gets so dry you have to soak it in water to start a fire with it! ; ) lol

That’s a good one Kindlingmaker :-))

Thanks for the thoughts boys, the links by Minuteman are quite educational. Looks like dry here on the left coast is wet on the high desert plain and there is no such thing as dry in the midwest ;-))

In his book, ” Woodworking Wisdom”, author Nick Engler states, under the topic of “Drying and Stacking”, the following;

“Stack the green lumber on a rack outdoors. Let the “free water” evaporate, seasoning the stack for three to four months during a time when the average temperature is above freezing. Then move the stack to a sheltered, but unheated, location inside a barn, storage shed, or garage to remove the “bound water”. The wood is ready to shop dry when the moisture content drops below 12 percent,”
