I have been hosting an invitation only private chat group for over 15 years now. There is a ton of information on this site and the searchable archives contain enough info to write several books. Maybe I should do that some day. 
Recently one of the topics that came up on the group was about torrefied wood. There seems to be a lot of misinformation out there about this wood and the torrefication process. Several years ago I was in Canada and visited the source of where most of the torrefied wood for the lutherie industry comes from. Of course, I had my camera with me and rolling while I interviewed someone about the torrefication process. This should shed some light on the subject.

Also, the free copy of my audio book, My Life as  Luthier and Instructor, ends in three days. Get your copy now. More information about the promo is available on my website.

Happy Building!
