Mark,
Do you intened to work out any of the coupling issues before releasing the plans, or leave it they way it is?
I think this looks like a great design for people like me, who want a good pattern plane that is easy to build. Also since there are no composite parts, it could easily be scaled down to say 75% size to make a very nice .40 size practice plane. I´m quite interested in doing that myself and build the full size one later on.
If I would buy the plans (which I´d really like to do), will you supply them "as is" only or will you supply them in CAD format as well if requested? The reason I ask is that I have access to free printing of plans of any size.
