Topic tags/keywords: air dry lumber wood kiln mc moisture content

I used my saw mill to cut 1” thick cherry slabs. They have air dried for only 2 months and are reading a moisture content of 7%. They can’t possibly be ready for furniture after only 2 months??? I checked other woodwork in my home and it is reading about the same. I thought 1” thick wood took a year to air dry? Help please…

You may be getting an incorrect reading. The surface of the wood will be much drier than the interior, cut off a small piece and read the moisture (fairly quickly) at the new cut…it may be quite a bit higher. If it is that dry, were they green logs when taken to the sawmill?

Where on your boards are you checking the moisture content?

I checked them on the edge and the face, then I cut one with a miter saw and took a reading. It was the same throughout the board. I cut a live green tree. I live in eastern Ohio.

Change batteries, clean the contacts. Check end grain.

try a different meter.
From your description, something is not Kosher.
Remove unknowns by process of elimination. First, batteries, then cleaning contacts, then use another unit.

Check wood at least 2” in, quickly after cutting on the end grain.

There are more, but you should be able to see where this is going.

I am with everyone else get another meter! I can get a surface reading just pressing probes into the wood, if take and awl & mallet to same spot will get a different reading.

Normally air drying lumber outside can get a MC between 15-20% in 45 to 60 days. Inside will be slower because do not same amount of air exchange as outside. Yes adding a simple fan(s) will increase air circulation indoors.

There are a lot of variable drying wood. The time of year you cut a tree down (sap running or not) species, density, relative humidity, temperatures and where & how you stack wood. That old 1” per foot per year does not take into account most of those variables.
