I worked on finishing up one of the two end braces tonight. I beveled all braces, counter sunk all the holes, filed all the corners. I did notice that I need to cut a bevel on the bottom (short) braces on the end brace so they will clear the stringers when folding and unfolding.
I see what Jonathan Abitz means when he said that cutting the notches in the braces on the mid braces that hold the side stringers up makes assembly tricky. I futzed and putzed tryibng to get the boat unfolded tonight. It folds up like a breeze, I just cant get the goofy thing unfolded for the life of me. I must be unfolding a part too soon, and having a brace bind up on me.
