Slow progress, but progress nevertheless.
I’ve altered a couple of things, so had to remake one frame.
But that’s done now, and I’ve all of them stood up, glued and screwed to the
bottom panel, and the interesection between the two filleted.
Note that I mask the fillets with plastic paint masking
tape, the ones that will be seen anyway.
It makes getting a tidy job much easier.
I peel the tape off as soon as I’ve got the fillet properly
formed, otherwise when the epoxy sets its very
hard to remove.
Note too that in order to make them easy to sand but still
structurally sound for a high strength application I sometimes do the fillet in two shots. One with
thickened glue using an 8mm radius tool for strength, then when its tack free
but still green I’ll run a fillet of low density filler such as microballoons
in epoxy over that with a larger radius tool. That makes it easy to sand and it
looks nice.
Back to the boatbuilding.
With all the frames up its evident to those with an educated eye that
she’s pinched amidships in the top two planks, that’s to keep the beam down a
little where the oars will be, Shes
about three inches narrower there than she would otherwise be, and that
translates into oars that are about 5in
shorter, an important issue when trying to stow them in the boat.
Why not just make the boat more slender? Loss of sail
carrying power, she’s relatively narrow on the waterline so she’ll row, but
wider just above there so when she heels she picks up stability very quickly. I
need all of the stability at 12 to 15 deg of heel that I can get but still keep those oarlocks at a reasonable distance apart. Its all about how to work the compromises.
Filleting to go in yet but the structure is beginning to look vaguely boat shaped. There is more room in the "cuddy locker" and in the Cuddy than in a SCAMP, and the cockpit is a good metre longer, has the last metre or so as a stand up place . She feels BIG right now, the last several boats I've built have been much smaller. I'm enjoying the work!
The next job will be to start putting in some of the
lengthwise pieces, the corner stringers between the seat fronts and seat tops,
they’ll act as some of the bracing needed to hold everything in place while I
wrap the stringers around.
While working on that I”ll be putting some extra pieces in
to spread the load from the big fairlead ( Chock) on the foredeck, the mooring
line, sea anchor and anchor lines all go through that and it’s a highly
stressed item so there will be extra bracing under the foredeck king plank to
take that.
On Monday I’ll be off to the place that has expensive pieces
of wood to buy some Western Red Cedar which I’ll rip up for stringers. Some of
those need to be over 20 ft long so I’ll
buy the wood at about 12 ft, rip it to
size then scarf it to get the lengths needed.
Four stringers 20mm x 30mm each side, plus the inwale, that’s the one
along the inside edge of the side deck and cuddy and supports the foredeck as
well. That’s ten scarf joints to make. The outer, or rubbing strake will go on much much later.
I’m only getting a couple of hours a day, and that not every day so I plan my work
around the time available, that sometimes means that should I get more time, I’m still waiting for
glue to set so can't do much. When that happened on Thursday last I decided
to occupy myself by sharpening a couple of planes and make a start on rehabilitating some beaten
up Marples Chisels I got very cheaply off TradeMe.
But sometimes patience, or tolerance wears thin. The toolrest on my Ryobi grinder and linisher
was a dreadful thing, too short, too flimsy, interfered with the hands as the
tool was run back and forth over the grinding wheel and, well, it was a pain in
the very low back to use.
So, out came the engineering tools, hacksaw, files, drill,
taps and such, and I’ve made a nice
toolrest from a 6in long piece of 1in x 3/16in mild steel, drilled and
threaded, cap screwed to the highly modified old toolrest, and beaten into
parallel and square with a few whacks of the middle sized hammer.
I didn’t get the tools sharpened, but did get one of the things that was annoying me out of my
life.
Priceless! I should do that more often.
Looking great John. At this rate you might beat me to the water!
