Tying it all up dry.

It took a bit of thinking and a few phone calls to decide not to by a gazillion clamps (although the tool collector in me got excited). With a lot of bulkheads and some tight curves the chine logs and sheer clamps will need consistent, firm and semi permanent control.

You also have to consider that to keep the boat straight you need to tie it up evenly one bulkhead, port and starboard, at a time. My calculations ran out to around 50 clamps.

Robert Ayliffe sorted me out, a quick trip to the big box hardware store and at $0.50 per bracket I had 50 clamps.

You can see they had to be used in two different ways due to access restrictions inside the boat. The inner chine logs can be fastened with screws only, and this was the fastest and easiest because the alignment of the screw that did the drawing in was not critical. In the sheer clamps, I had to use a nut and bolt so the hole had to be drilled and aligned prior to snugging up.

Importantly this must be a dry run first starting from the attachment point, which is the bow, and working aft where the timber can run off. As expected the bow quarter was tricky but the stern quarter required some serious force to make the compound curve.

This force applied at the aft bulkheads even resulted in bulkheads lifting out of the jig, so those extra brackets were put to good use anchoring the last four bulkheads to the gig.

You can see in the photo the timber run off provides leverage for a spanish windlass to help with the clamping.
