Trial of systems

here are a few pics of some trials of the blind dovetail grooves and folds that i used or tried to use in my model. as i said in the last post the dovetails would have worked apart from the way that the folds had to come in the locking system became too weak as it had to be forced past itself to lock in. the v- cuts became very hard to work out how much mass needed to be cut out with the unusual angles that i planned on using. as a result i went back to the formula i worked out on a previous post.
