Installation of some structure to support the deck came next. The position of the deckbeam was measured relative to the forward bulkhead. The pair of arched, precut plywood pieces had been previously epoxied together, forming a strong beam unit. Holding the piece in place, the ends were marked and cut, then bevelled and planed until they fit snugly in place between the sheer clamp in the correct position. Pilot holes were drilled and countersunk for #8, 1-1/2" bronze screws to hold the beam in place. Next, the centerline was measured by dividing the beam by two. This matched well with the centerline position given by a string stretched from bow to stern on the hull. From the plans, the position of the wood blocks were marked on the deck beam, and these were also drilled and screwed into place. Once everything fit satisfactorily, it was all disassembled. Some mustard epoxy was mixed with silica, and the parts were coated at the joint faces. The beam and then the blocks were screwed back into place. I had intended to install the carlins as well, but decided to let the deck beam parts cure before that. Besides, I only have two bar clamps, and will need two more to do the carlins... Total hours 17.00.
