2016.10.09 - A Template's Tale II

Having created the template the next task was to cut and fit the plywood. This took about 45 minutes. The process of drawing around the template produces a pencil line just bigger than the template itself. The cut is then made on the waste side of the line making the workpiece slightly too large. This is then carefully trimmed until it fits into the space. The trick is to make the plywood very slightly too small so that when it is fitted the sealant has somewhere to go. Make it too tight and all the sealant will scrape off in the process of fitting.

And there we are, one partition.

The cross-line laser was now put into a lot of use as the construction of the cockpit seats and stowage requires some lines and measurements marked on the hull. The seats are going to be the same height as the bridge deck and extend just a little bit further back than the forward edge of the poop deck. Here you can see the laser being used to transfer the line of the poop deck down onto the hull below.

I put a support under the aft end of the keel so that my weight in the back of the boat would not change the level.

The laser line can be seen touching the edge of the poop deck and on the hull below. In total about 1 3/4 hours was spent in carefully marking out the required lines and working out where things were going to go.

For example, the stowage under the poop deck will have a "shelf" of slats at the same height as the seats. If the seats only extend to the poop deck then the slats will need to be 680mm long. The slats come in 900mm lengths, so it I make the seats extend under the poop deck by 80mm, then the required slat length is 600mm meaning that I can get 3 slats out of every two 900mm lengths. I want the seats to extend further than the poop deck anyway so this is a winner all around.

Still, 2 1/2 hours of work for very little visible result, just a partition and lots of pencil marks.

Time for lunch!
