Round the Bend




As mentioned in the last blog we have cut in a strip of cedar to define the cockpit deck joint. The strip is continuous and let into the bulkheads. I will update the plans to reflect this and the bulkheads can be cut with this notch when loftng/CNCing the bulkheads; this way the strip will just drop in. You can see how the removal of the coachroof bulkhead has aided this process.

Gerry is at the boat today doing the hull to deck joint. He is using plywood from a printed template that I have provided; it is a developable suface (one degree of curvature) and should fit exactly. However, I am contemplating using the same size strip of cedar at the chamfer (minor mod required to the drawings) as this will again allow this very visible part of the boat to built fair as well as the providing a stiffer corner for the plywood to butt up against before taping.
The side decks have been butt joined together and are ready to go on. We used the exact same method as we did when making the hull planks. We have offered them up to the boat but the fit does not appear perfect; it seems there is too much curvature in the deck for the computer to produce an exact developed surface. We shall see what fun we have when it comes to putting it on for real(!) but I think the best way to proceed is to remove as much deck camber as possible from the design so we know that a pefect fit can be achieved from the patterns. After all the aim must be to produce a pack of plans which fit together with as little modifaction as possible.
