I'd like to discuss, in the next few months, a few examples of groovy ways to engineer a boat kit and build a boat. The first photo shows the side girders of the CNC cut strongback. This has been one of the gbuildest aspects of creating kits. In a few hours time, the strongback can be built and the chipboard molds attached via precut slots cut in mold and girder. If you make "Spock hands" with your left and right hands and insert left into right, you'll get a good idea how accurately and easily a CNC cut strongback is to set up. Even these two dogs were able to do it, no sweat!
The second photo shows the chipboard bulkhead supports that slot into the girders and then are locked into alignment with a long batten which slots into the supports and automatically squares up the set up. These chipboard components are made out of 1/2" and 5/8" Advantech chipboard which stays quite flat. These chipboard components DO NOT become part of the boat.
The third photo shows the bulkheads and other marine plywood components of the boat mounted on the setup. Notice how the strongback catches the top of the stem so it locks into place. Anyone who has mounted a stem in 3d space over a strongback can immediately see how nice this is! You can also get a better sense in this shot how the supports slot into girders.
Next time I'll try to get some additional close ups of the alignment features of the building jig unique to my kits. These photos are courtesy of Jim Levang building hull #1 of the Calendar Islands Yawl. His build is at https://plus.google.com/115449767543136477921/posts/26mVWdN9FPd
