I have roughly 150 – 200 board feet of black walnut that I have been air drying for 18 months. The slabs still have the bark on and are 8/4. Would it help the drying process if I skip planned them before I restacked them? Last I check the moisture several months ago they were between 8% – 10%

I do not know where you live but this sounds like equilibrium moisture content for where I live. That means they are as dry as they can possibly get air drying. You would have to use some type of kiln set up to get the moisture lower, put them in a hot attic or in a tent with a dehumidifier

Currently I have the slabs in a basement and I will be moving them into the attic of my new shop in the next few weeks. Unfortunately the weather is getting colder so the attic won’t be as hot as I would like for awhile. Without utilizing a kiln will I be able to use it eventually?

I like in central Pennsylvania

For where I live in S.E. Missouri 8-10% would be considered ready to use. If in fact its 8-10% all the way through the slab, not just the outside surface.

Here in the Pacific Northwest 12-15% moisture content is perfect for building furniture.

If the walnuts are native, you are good to go. They are ready for your projects.

What differences should I expect when working with air dried opposed to kiln dried?

I was going through my stash of cherry this weekend and I found a large set of bookmatched slabs that I am going to use for our new dining room table. The outside moisture label varied between 8.5% – 9.5%. I am gonna let it dry over the winter in the attic of my shop before working with it.

Air drying, that’s about as good as it gets.

I have heard that wood dries faster if you do not plane it. I don’t know if that is true however.

They are as dry as they will get at this time of year. They may dry very slightly more if brought inside.

I would use them right now but I have several orders for chairs that will take me into next year so for now they will sit and maybe dry a bit more.

If you live here in Las Vegas they might need more time, but for most parts of the country 8 to 10% should be fine to use.

Thanks everyone. Hopefully I will have time this winter to start our table.

Have your say...
