This pic should give you a good idea of how my workspace seems to be shrinking. I deviated from the normal spar jig by adding sides of 3" aluminum angle. This was done mainly to ensure squareness - I had heard some troubling stories about trying to find suitable wood sides that were completely square and straight and I knew this wouldn't require lots of sanding to get them that way. A little more expensive to go this route but very sturdy and very square !
