The building plans arrived April 2004. The first step was to transfer the bulkhead measurements to the marine ply panels and to cut the bulkheads. I had to construct a working table large enough to hold the largest bulkhead, something that was absolutely worthwhile. Working on a floor surface is a backbreaking experience. So, my first suggestion to prospective boat builders would be to construct a working table.
Some bulkheads are 9 mm thick while others are of 12 mm thickness. The larger bulkheads are bigger than a standard 1.2 x 2.4 plywood panel. Therefore a woodworking technique that needs to be learned right at the start, is the scarfing of plywood.
Cutting the bulkheads is easy if one makes use of a router with a 6 mm bit. The strait lines can be cut using a straight edge as guide while the curves can be cut using the router's own guide with center pin. I found it very difficult to cut nice smooth and straight lines with a jigsaw, even after a number of years practice. On the other hand, the router produces a very smooth and accurate cut.
By the end of 2005 all 9 bulkheads were finished and ready for setup. It took 374 man hours to get to this stage.
