Canoe number two

Building another Prospector 16. I really like the one I made a few years ago and I have the forms, so why not?

I got a beautiful yellow cedar plank from a friend who bought several from a sawmill in Canada--old growth trees reclaimed from the bottom of a lake. Now I'm ready to start making strips.

First job is to rip the 1 in. blocks off the big board. I made a long series of supports by screwing rollers to my cabinet saw table, workbench, another table saw and finally a couple of outfeed supports. What a funny picture !


After all that, the Grizzly kept overloading the circuit, so rather than mess around with it, I sold it and made a mobile base for the Unisaw. Made enough money selling tools on Craigslist that I can get a couple of GripTite magnetic featherboards and a Kreg Precision Miter System.


Well, I rearranged the shop and turned the Unisaw around 180 degrees. Cutting the plank on the big Unisaw was easy and I got the strips all ripped in 2 days. When I get a spare day, I will do the bead and cove thing and we'll be ready to make a canoe!

Canoe building tips

My first canoe...see here, was a little bit of a challenge and I'm ready to do another with some experience under my belt. Don't get me wrong, my canoe handles well in the water, I'd just like to show off a little ;o) John Lucking in Eagle River builds some beautiful strippers and I went to his shop this week for some tips.

He gets yellow cedar lumber from a small mill in Canada-2x10x20ft quarter-sawn boards are what he uses to cut the strips from. That is one area I don't have a source for yet, but decking cedar works well too...just not as homogeneous in color.

This is what I took away from the trip:

1. Use 5/16" bead and cove bits to mill the 1/4 " strips for a tighter fit. John seems to like 7/8' width on the strips.

2. Don't staple, but clamp strips to forms with squeeze clamp. Each form has cutouts to accept clamps. Use a long clamp to pull the strips together if necessary. This is visually pleasing, and is a LOT less work than pulling about a thousand staples.

3. Assemble with the bead up so clamps don't damage the cove....although, using an appropriately sized dowl in the cove will protect it if you want to do it that way.

4. If using an accent strip, lay it first and add towards the sheer second. Lay the accent strip so it rises up toward the ends. An accent level with waterline will look odd.

5. He builds with a small interior stem and a cold laminated Ash nose. The inside of bow and stern are covered with a small feather-shaped piece of plywood. Avoids the necessity of cleaning up that nasty area of fiberglass and is a little cleaner looking.

6. After laying up the strips, the ends of canoe are belt-sanded flat and a notch cut in the "keel" to accept the ash laminations. Laminations are clamped with bungie cords and or nails until dry.

7. Gunwale sections are 5/8" Ash. He cuts scuppers in the inwale and screws them together. I personally don't like the extra weight of metal, and epoxy certainly won't fail.

8. Finishing West System 105/207 and Behr varnish

Sand outside of hull. lay glass on outside. One layer of 6oz is all he uses--no extra 'football'. Sand the outside smooth. Flip the hull and lay interior glass, sand.

Glass resin inside is layed with latex-gloved hands, mixing 5 pumps each of resin and hardner per batch.

Add the gunwales and decks, cut the painter hole in and whatever else.

Flip it upside down again and finish the outside/varnish. Clean up the drips on gunwales and finish the inside with non-gloss varnish. Use high gloss on brightwork.

8. Seats hang from inwales with wood cylinders for spacers and brass bolts. The whole assy is epoxied together. I like the idea of using trapezoid shape spacers to minimize the tendency of the seat to rock.

Building a Cedar-strip Canoe

I had a hankerin' to build a canoe a couple of years ago. There is nothing quite like building your own boat, and I sure as heck wasn't going to pay $3000 for one from REI!

After a bit of research, I found Gilcrist's book and decided on a plan. Unfortunately, there are no local suppliers of cedar strips. Walking through Home Depot one day I spied a new unit of 16 foot cedar 2x6 just looking for a home. I picked through the entire unit to find 6 relatively clear boards.

We sawed them into 1 inch wide strips, turned those 90 degrees and cut 1/4 in strips, After that, I ran them through the router table beading bit, then the cove bit.

Next the strongback was built of 2 x 6 fir and station molds attached. Once they were plumb and fair, I taped all the station edges with masking to keep glue off them.

Sheer planks positioned and laid. Then it is just a lot of glue, staples, nails and time. If you click the image you can see all the staples.




















The fiberglassing didn't look as nice as I had hoped.....all glassy smooth and professional like the images on web. I mistakenly thought the epoxy would fill any voids and sanding the surface perfectly flat was a waste of time. Oh my, was I wrong. When I laid the glass I found that the cloth just tents over the gaps and leaves a white spot.

Canoe version 1.0 had 3/4 x 3/4 ash inwale and outwale screwed every six inches and ash decks about 12 inches long. Beautiful but a little heavy. The boat weighed almost 70 lbs. The seats were fairly large too and I used cane for the seat. The cane tore, so I took off the gunwales, decks and seats and replaced them with 1/2 x 3/4 fir inwales and outwales -- not screwed but epoxied. I added little trapezoid shaped doublers where thwart and seats attached. Seats were ash 1x2 but only 7 in wide. Now the weight was only 55 lb. Much nicer now for portaging. The total cost was less than $600, most of which was the glassing material.

Well for a first time job, it turned out ok, and heck it floats! We have enjoyed many trips to the Kenai canoe trails -- impossible without a boat.




















So, on th next boat I will do more surface prep before fiberglassing, But gee, I'm having an awfully good time right now, so it might be another year.
