I am in the process of making a small keepsake box and I want to put a panel of spalted maple in dados for the top of the box. The wood is from a tree from my yard that came down and as of now the moisture content is 14%. The piece is going to be approximately 5″x10″ and will only be in the grooves after I cut the top from the completed box. Will I encounter any problems from the moisture content and the size of the panel.

If your are concerned, the pieces are so mall you could heat your oven to 120 degrees F. and put the wood in there overnight, it should be down to 4-6% in several hours. With those small size pieces I would not be too concerned but there certainly will be some shrinkage if your RH in your area is 30% or less.
thanks for the reply. I thought that with the pieces being that small that I would not have to many concerns, but it never hurts to ask.

For a piece that size you could put it in the microwave at a low setting for half an hour or so.

David,Did you really mean microwave or just conventional/toaster oven?Chris @ http://www.flairwoodwork.spaces.live.com(soon to be http://www.flairwoodworks.com)

Microwave. It's very effective as a drying method because it's not based on heat applied from the exterior. It's currently in limited commercial use because of the cost, but there are a few microwave drying facilities. My son bought the Douglas Fir posts and beams for his timber-frame home from Timbercraft in Washington state. They were dried in a large microwave facility. And BTW, are still in perfect condition 6 years later. I have used the microwave oven at home to dry green pieces of olive wood. Works just fine.David Ring

Hi sfmc,
The equilibrium moisture content here in our part of Australia is 12.6%
It changes depending on whether or not you are in a dry area, the house is air conditioned, etc...
Google "equilibrium moisture content" and your city - I'm sure it will bring up the moisture content to work with. Note that, as per the link below, the EMC is the outdoor value. If your inside air is hotter or air conditioned, then the humidity value is lower.

The EMC basically depends upon the average humidity of the air in your location throughout the year. THere will be swings between the summer and winter seasons.
Cheers,
eddie
