One of the four hullsides being joined together with butt blocks. A piece of scrap blocking is put on top of the actual butt block so that the screw heads don't penetrate into the finish piece. The parts are held in place on the work tables with lead bags - each one containing 25lbs. of lead shot. These are great for applications where you don't want to make excess screw holes.
Here's what the finished hullsides look like, after joining together and coating with epoxy. These are all done and ready for assembly. With a crew of four and enough tables for glueing it does not take long to prepare the parts.
