Spindrift 11: Going 3D
September 20-21, 2013
last we left the Spindrift, the two 'wings' had been made and
she'd been zip-tied together. The next step was to see if we could
make a boat of her.
NOTE: A much smarter, more patient man would have pre-coated all
the parts with epoxy and allowed them to cure before gong 3D. 2
coats on every part that will not eventually be covered with fiberglass
(most of the interior,) 1 coat on parts that will be covered with
fiberglass (most of exterior.) Why? Because it is MUCH easier to
get a nice, even coat when the parts are lying flat. Once it is
3D, you'll have to contend with runs and drips and digging around
NOTE NOTE: I forgot my camera this week - everything you see is
from my iPhone. I don't have any pictures of the start because A)
I hadn't thought of using my iPhone and B) we - the 3 of us - had
11' of wibbly-wobbly 6mm plywood to stand on edge and stitch together,
kinda tough to be taking pictures when you are worried about catastrophe.
If you remember, the strake and garboard were fiberglassed together
at the bow prior to going 3D and we'd drilled all our holes along
the edge of the garboard, but not the strake because we didn't know
how the wood was going to meet up in it's final form. Bob steadied
the stern while Curt and I matched the edge, drilled the hole in
the strake, and inserted the zip-tie.
Son-of-a . . . . THAT was EASY. Drill, zip, drill, zip, and all
the sudden, it's boat shaped.
I didn't get a shot of placing the transom, you'll see that later.
Things were pinchy at the bow and we had to play "Whack-a-Bulkhead"
to get it into place. We'd pre-drilled small holes on the line for
the bulkhead, then carefully drove drywall screws into the plywood
on edge to hold it in place. This method worked great.
At the last minute, I decided to not make the nesting version of
this boat, mainly because, even nested, it wouldn't fit inside my
Subaru. What would have been one of a pair of interior bulkheads
is now a temporary bulkhead.
We needed to tighten the zip-ties down the centerline, so we flipped
the boat over. Proper procedure? I don't know. It worked, so, yeah,
I guess it is proper procedure after all. Look closely at the corner
at the transom: See how the edge of the bottom overlaps slightly?
That's called "poor measuring on my part" and is a hallmark
of boats I've built. Don't worry - a few seconds with a belt sander
and we'll be right as rain.
My 'toothpick dipped in glue' (patent pending) method of filling
screwholes. We finished out the evening by putting a tiny bead of
thickened epoxy along all the seams - tacking the boards together.
Saturday morning, we cut the zip-ties and got a good look at our
Oh, that's a purty shape.
We spent the rest of the morning making fillets with wood flour
and fiberglass tape. I took out the temporary bulkhead as it made
little difference in the shape.
Next time: Cover everything with epoxy and add seats.
