With fairing finished, time to return to some real boatbuilding — which in turn led to more fairing.
The topside stringers are the long, thin members that provide a bonding surface for the topside planking. They are curved for roughly the forward 15 feet of the boat, so the slots that they go in have to be beveled (faired) in relation to the angles on the frames to produce a nice, flat, surface for the planking. That meant over a day’s work with rasp, file and in a few stubborn areas a Fein multitool saw to get everything squared away — I mean angled away.
The straight aft stringers are 1.5 deep and 1-inch wide. They are fabulous vertical-grain douglas fir from a stash of at a local lumberyard that knows what I’m up to and pointed me to the right pile. On one 3 1/2 inch board that I was cutting down to make a stringer I counted 43 growth rings. That tree had been growing that piece for 43 years for the Tardis. I went back and did a little more fairing after that trying to get things perfect for that one piece of wood.
The laminations for the curved parts were 1/4-inch strips 17 feet long. Ray came over to help me get them in the slots, since they flopped around like linguini after about two minutes in boiling water. We thought about laminating the stringers on the boat, then taking them out to get the tricky angle with the stem just right. But with Ray holding tight, I was able to get a pretty decent cut with a Japanese saw, so we just glued them on. The laminations are just butted up to the stem and a support block. I thought about cutting some sort of compound angle pocket in the stem to receive the laminations, but went with the high epoxy approach since a) I didn’t want to weaken the stem b) that would require craftsmanship.
The string and 2 X 4 supporting the forward clamps in the pictures give the forward laminations an extra bit of twist to get them lying just right. Crude, but it works, and whatever works when 17 feet of laminations are turning to rock is good with me.
