I,d like to discuss wether to air dry or kiln dry wood.Me and my two boys have accumulated about 4000 to 5000 board foot of various hardwoods. Some from farmers who have let us have some downed trees, some from the shed of my late brother in law and I have purchased some logs from a timber man. Some of the wood has been in a shed for 50 years but it does,nt matter it still moisture tests 12-14%. We havn't had any disasters but we have had more shrinkage than we would like and one book shelf that has a slight warp.
Air drying;
Advantages:
1. Grain is more prominate
2. Wood machines better
3. Bends better
Disavantages:
1. More movement from seasonal humidity changes
2. More potential for warpage
Kiln drying:
Advantages
1. More stable. According the guys at the kiln all of the water in
the inner cells is evaporated and the cells are collapsed precluding
their ability hold moisture and the heat hardens the wood tissue
making it more stable. They said although all wood will experience
some movement it will be much less than air dried wood.
Disavantages:
1. cost if it is not necessary
2. Loss of the ability of the grain to stand out
I have 2 loads being dried right now But I have read in fww statements
by some professionals that they don't kiln dry their wood that they use for fine furniture. what do you all think? Thanks Barry
