      Paul J. Bois, a wood drying specialist, writes in this quick article about how the kiln is built and works, how Johnson monitors it, and what the moisture rates are as the wood dries, winter and summer.

Our approach was to build and operate a small dehumidification dry kiln. The four. Freshly sawn hardwood lumber is perishable, with delays or improper handling often resulting in lost revenues for producers.

As green wood dries, most of the water is removed. The moisture remaining in the wood tends to come to equilibrium with the relative humidity of the surrounding air. Correct drying, handling, and storage of wood will minimize moisture content changes that might.

End checks are a common problem when drying wood. Sometimes they aren't too destructive and don't travel too far, but other times they make the end of the lumber completely unusable or make a nice wide board into two not-so-wide boards.

These cracks form on the ends of lumber because the ends are drying out. The quick drying firewood. Cherry, which might take around months; Rock elm, black locust, apple, pear, and other fruit woods and elms dry for at least 6 months. The long drying firewood.

Wrapping a freshly turned green bowl in sheets of newspaper or putting it in a paper grocery bag can create a sufficient vapor barrier to allow face grain to dry at about the same rate as the end grain.

Some turners also paint the freshly turned blank with wax-based wood sealers used by the forestry industry. Hardwood lumber may be dried for many reasons. First, drying increases dimensional stability. Wood shrinks considerably more across the grain than along the grain when it dries.
