Hi Thomas,
Thank you for sharing your experiences with us. This is probably one of the most valuable contributions ever made on these pages.
I think that almost every timber framer who has ever tried to build a timber frame must have had similar experiences.
You now "know what you don't know" and I suspect are now ready to research, learn more, experiment and in so doing develop a capability to teach others about how to deal with these type of issues.
I feel another Jack Sobon coming on.
Regards
Ken Hume
