Lotesl Techniques in Drying

The latest techniques for drying wood faster and better will be emphasized at the 87th Kiln Drying Demonstration at the U. S. Forest Products Laboratory, Madison, \flisconsin, March 25 to April 5, 1963.

"Today the man who dries lumber is a key production figure," points out Dr. Edward G. Irccke, director of the Forest Products Laboratory.

"We are moving toward ever more highly refined products," he explains. 'oSeasoning thus becomes more and more critically important in high-speed productiono not only to shorten production time but to facilitate other vital processing steps, such as surfacing gluing, joining, and finishing.

"At the Forest Products Laboratory we have long recognized this by pioneering special training demonstrations in the kiln drying of lumber."

During the 2-week training session, the participants will receive instruction in the use and care of moisture meters, balances, drying ovens, recording-controlling instruments, and other dry kiln eguipment.

The laboratory's stafi of seasoning specialists will present the information in simple, easy-to-use form. Men with individual seasoning problems will be able to discuss them with any of the FPL specialists.

A recent Laboratory publication, the Dry Kiln Operator's Manual, will be used as a handbook for the session. The manual was written by E. F. Rasmussen, FPL seasoning specialist who is directing the demonstration. It includes such information as basic principles of kiln drying oI wood, types of dry kilns, kiln equipmen! operation and tuneup of kilns, drying schedules. and moisture control of lumber and products during storage and production.

Since March 1919" when nine furniture manufacturers attended the first kiln drying demonstration, participants have included plant managers, engineers, super- visory personnel, lumber dealers, architects, and woodworking specialists, in addition to kiln operators, Many have come from foreign countries.

"Wood products of all kinds must be continually improved to hold existing markets and expand into new ones," comments Dr. Locke. o'Moisture content control in wood processing is critical in this quest for quality."

Cooperative fee for the 2-week demonstration is $275 per man to cover Laboratory expenses, and includes materials and publications. It does not include travel or living expenses. Each firm may enroll as many representatives as it wishes.

If you have south or west exposed rooms which pick up a lot of summer heat, try building a simple solid frame of 2x4 Douglas fir set on 4x4 posts with simple lx4 louvers spaced a foot apart. This gives an eye shade efiect, will cool ofi the windows and provide filtered shade.
