rf microwave kilns

Hello. Doing some research to find out more about the new microwave kiln technology and its effects on larger timbers. Trying to create a plan of attack for a new project. I would be thrilled to have your input.

I am considering microwave tech to dry some old growth soft wood blow down timbers I am harvesting.

I have several questions. Thank you for making an effort to assist me. #1 What seems to be the consensus on the pluses and minuses on this new technology as it would apply to timber framing? #2 Do you have any sources for people doing RF microwave drying on large scale timbers? #3 If you had the option to air dry extremely wet (25-40% MC) soft wood timbers for four months prior to construction, use a low tec, kiln for drying, or explore microwave kiln drying, which way would you go? These timbers will ultimately leave an extremely wet northern environment to be utilized as a timber frame in a dry mountian climate averaging 6%-8% M.C. The lumber will be cut from beautiful blown down, old growth whole logs we are salvaging and I would like to make an attempt to give this wood the best shot at being happy as timbers in this new environment.

With great respect,
am

There is an ad in Timber Framing issue #60 for an outfit: Fraserwood Industries at (604)-892-7562 or [URL=http://www.fraserwoodindustries.com] who dry timbers using rf/vacuum kilns. You could try their site. Good luck Jim
