What alternatives are there to using “green” wood?

There are two alternatives to using green wood: recycled timber, and kiln or radio frequency kiln dried timber. Recycled timbers have become popular for use in timber frames for environmental as well as aesthetic reasons. These timbers are salvaged from old factories, mills, and railroad trestles. They are often of very high quality and are dimensionally stable from decades of drying. Recycled timbers are the most expensive timbers available at the present time. But the look and beauty of using antique cedar, Douglas fir or yellow pine cannot be duplicated. Radio frequency (microwave) dried timbers are new timbers that have been kiln dried to eliminate the majority of shrinking and checking.

 
 
Tom Musco, the founder and principle timber framer of Royalston Oak, began his professional woodworking career as a musical instrument apprentice to Peter S Kyvelos in Belmont, Massachusetts in 1973. Tom spent several years making and repairing a variety of Middle Eastern and Western stringed musical instruments. One of his dulcimers was featured in the first Fine Woodworking Design Book in 1976. Tom and his wife Judy moved to Royalston, Massachusetts in 1977 and began building timber frames, an interest he discovered in a beautiful timber-frame barn on his in-laws farm in Petersham, Massachusetts. His first frame was for his shop and his second frame was for his house. He made furniture and timber frames until 1980 when his shop was struck by lightening and burned to the ground along with all his tools and machinery. He built a new timber framed shop with the help of his neighbors and began timber framing full time. Tom was a founding member of the Timber Framers Guild. He has done workshops in NE ( Pembroke workshop at TFG ) and England. In 1989 Tom and his crew participated in the famous Concord Barn Raising episode of This Old House. He has built timber frames in New York State, the Hamptons, Tennessee, North Carolina, Alaska, and all the New England states except Rhode Island. Tom has crafted almost 200 timber frames since 1977. Tom is also an excellent cook with an interest in food of Sicily, where 3 of his 4 grandparents were born. He has written a series of articles on Sicilian food which you can read at the website of the Umass Journalism in Sicily Program.
