Hi Charlie,

You are correct: In the past frames, knees, stems, etc.  would be made with wood that "wanted" to go around the corner.  Sometimes a crook, sometimes an air-dried timber which was then steam-bent. My intent in adding that to the outline was to describe the typical 3 piece, glued up stem assembly or a frame which is made of as many as a dozen parts.  All of those joints are weak points.

The glues available in earlier days didn't allow laminating parts with any hope of longevity.  A few months is not enough.   Epoxy as an adhesive has solved a lot of the problems of the modern boat builder. It has also allowed us to laminate parts.  That means that you can build 100 boats and have the parts virtually identical to one another.  They are strong and light and repeatable.

If you are interested, I'll be going through the process as a demo on Saturday 10:00 at the boat shop.  Trying to share what I've learned about making this stuff go around corners.  (The good, the bad and the ugly.)  The more the merrier!  I have a 'raw' finished lamination and its mold along with a finished frame which is ready to go into the boat.  Lot's of photos.

I find that I usually learn more than anyone else when I have to present something like this.  Which is why I do it!  

Cheers!

Mark
