Stitch & Glue canoe, the Blogg (see bottom of page for more self build stories)
I
first had the notion of building a canoe a few years ago, but put it to the back
of my mind, where it might have stayed had it not been for our holiday to
Canada. Suddenly there were canoes everywhere, and being used for all sorts of
things – transport, camping, fishing, sailing, you name it!
Of course, when
we got back home I started to look into buying a canoe. Now again, I probably
should have stuck with this, forked out a sum equivalent to a second hand car
for something made of Royalex, and lived happily ever after. However, I’m not
quite that sensible, and like so many others it turns out, I found myself
surfing the Selway Fisher website.
The pics looked great, and suitably enthused
by the marketing blurb about building my own canoe in 2 weekends flat, at a cost
of no more than 50p, I ordered the plans for the Fisher
Prospector.
Now, here’s the rub. You must understand at this point that the only
thing I’ve ever made out of wood before was a rather fetching egg rack which I
made at school (I seem to remember getting a D for that even!). So, this blogg
is posted purely to say “If I can do it, so can you”. It is not a tutorial in
the finer points of, well, anything really! Right, that’s the scene set, let’s
start building!
1) The plans came in the form of two A1 drawings,
plus a few sheets of A4 on the building process. The canoe is symmetrical, with
5 planks per side. This means that you need four of each plank to make the hull.
This is made easier by marking out one of each only, and using this as a
template for the other three. All four planks can then be planed up together
(take your time over this, it’s one of the best bits
).

2) The next job is to join the ends of the planks together to give the full
length of the canoe. There are lots of different ways to do this, but I settled
for tacking them down on a sheet of sheathing ply, with acetate sheet underneath
to stop it sticking. I found that I could lay all of the planks side-by-side
along the sheathing ply, so that all of the joints were in the same place. I
then primed the join with epoxy resin, and slapped down some 3” glass tape, and
waited for this to cure. I was then able to cut the tape between the planks,
turn them over, and repeat for the other side.
3) Now the fun really
starts, as the canoe starts to take shape. By laying the planks together, and
starting from the centre of the canoe, they can be ‘stitched’ together. This is
the ‘stitch’ bit of stitch and glue! You can use cable ties or copper wire to
hold things together. I went for the wire, and it worked perfectly. The photos
below show the hull starting to take shape. Getting to this stage is incredibly
quick (2 weekends maybe?), but don’t open the champagne yet – you’re only 20% of
the way there!

4) Now the ‘moulds’ are inserted to give the canoe
its proper shape. I didn’t get a picture of this bit, but basically these are
like bulkheads made from scrap ply, which are wired in vertically to give shape
and rigidity. It’s then well worth spending time checking that everything is
true and to the right dimensions before anything is set in stone (or epoxy). As
you can see from the right hand photo above, the bow was distinctly squint to
begin with, and needed quite a bit of work to get it to
behave!
5)
The next job is to tack weld the planks together using epoxy resin,
so that the wire stitches can be removed. It is possible to leave the stitches
in, and just epoxy over the top of them, but I’m glad I removed mine. I had to
leave a few in at the bow and stern, and these gave me all sorts of bother when
fairing the hull later, so all in all, I’d recommend the tack-welding, prior to
removing the stitches. For the tack-welds, I used a countersink drill bit along
the joins to make a small hollow, every 6” or so. I then filled this with
thickened epoxy, and it worked a treat. The only drawback is that this method is
that it’s visible in the finished job. However, coming back to the egg-rack, I’m
not a perfectionist, so it didn’t matter.

6) Once I had finished the tack-welds, and removed
the stitches, I cut up the moulds so that only a single strip remained to give
the correct width at the top (as seen in the photo). Even with just the
tack-welds in place, the hull is surprisingly rigid at this stage (not that
you’d want to paddle very far in it yet of course!
)
7) Removing most of the moulds leaves the length of
the canoe open for the glass taping. First, a ‘fillet’ of thickened epoxy is
applied to seal the join, and give a smooth curve for putting the glass tape
over. This is quite a tricky task – a bit like trying to apply peanut butter,
neatly along a 15’ curve, but with it setting and going lumpy as you go! In
hindsight some of my fillets are a bit on the big side, but if anyone laughs at
them, I’ll break out the peanut butter and challenge them to do better! I then painted un-thickened epoxy over the fillet, and applied 2”
glass tape to the join. This then has more epoxy brushed into it until it is
completely ‘wetted out’ (i.e. it goes clear). This is the one place where things
went a bit pear shaped, since it was January, and flippin’ freezing in the
garage! I think this is what made some of
the epoxy go a milky colour, which shows up badly in the final finish. However,
you live and learn, and I certainly wasn’t waiting till June to do it in any
case.
8)
The hull is then turned over, and the gaps where the panels meet
are filled with thickened epoxy. When they are first stitched together, this is
done so that the inside corners of the ply touch. This gives a gap on the
outside of the boat, which can be filled to give a nice finish. This was a
fairly easy job, but took forever and a day, (laboriously removing the sand from
sheet after sheet of sandpaper by hand is hard work!). One tip I’d give is to
wait until the epoxy is half-cured, then go at the proud stuff with course
sandpaper. It’ll rub off a bit like when you use a pencil rubber. I managed this
for a couple of the joints, but by the time I came to the rest, the epoxy had
set hard, and needed LOADS of sanding. The problem is that the epoxy is then
harder than the wood, so it’s not as easy as it
sounds!

9) Just for good measure, I then sealed the outside
of the hull in epoxy. This adds rigidity and water protection, so should ensure
the boat lasts a long time. I had always planned to paint the hull anyway, but
even so, it was quite a wrench to have to say goodbye to all that lovely wood!

10) The next job
was fitting the gunwales. This is where the real woodwork began, and I started
to struggle! The first problem was sourcing strips of suitable wood. I
eventually found a place in Edinburgh who would cut it up for me, but the only
wood they stocked in the right size was dressed oak, and opinions were divided
on it’s suitability. In hindsight, I should have done the inwales in Douglas
Fir, and the outwales in Mahogany or similar, but you live and learn. Anyway,
the oak does look lovely! I had a real job steaming the gunwales to fit (here’s
a picture of my first, entirely unsuccessful attempt!).

I
eventually made a steam box from a section of drainpipe, and just about got it
to work. The main problem was that the wood only stayed flexible for about 30
seconds once out of the steamer, so lots of swearing and bending ensued.
However, I’m now willing to challenge all comers to a G-clamp speed test! Won’t
write any more here, but if I ever build another canoe, I’ll need to rethink the
right way to do the gunwales and the steaming process!

11) Once the gunwales were on, we were home and dry –
just the seats to fit, then some painting and varnishing to finish off. Being a
dinghy sailor, I couldn’t contemplate a boat without buoyancy tanks (after all,
£5 worth of ply, or £50 for airbags?!). In hindsight, these are less useful than
I’d hoped, due to the huge amount of rocker on this boat. However, they do make
a neat place for storing sandwiches! The story behind the design is that I asked
my wife to come up with something classy – a celtic knot maybe? However, she
decided I was taking this boat building lark far too seriously, and looked to a
fluffy friend for inspiration. I don’t have a decent photo of this yet, but
suffice to say, if the Moose’s head ended up on the bow, you can guess what the
stern looks like!

12) So that’s it! A winter’s worth of weekends,
happily spent in the garage. I’m now a bit wiser in the ways of woodworking, but
certainly no expert. However, I have proved that it can be done, and if I can do
it..........
SO CAN YOU!!!



Just got to learn how to paddle the darn thing now!
