Atkinson Traveler build; inwales & ribs

If I go with the alternative seat weaving, I'll probably make thwarts and seat rails like this. Just a quick & dirty experiment so far on a piece of Spruce. Tapered ends, gently radiuses edges, tapered upper surface on an arc as well.

On a different topic, I have a number of small knot holes to fill in my planking. I managed to put most of them on ribs so with the exception of two minor spots. I thought of filling with a two-part wood filler but I'm concerned that the resulting hard filler could detach and migrate under the canvas after some time. Any alternatives? Maybe just linseed oil based window glazing? That's apparently what I've found on several restorations.
 
Patrick, Some folks use fairing compound. Some use bondo. I have fairing compound handy so that's what I would use.
Change of subject....the tacks on that plank to the right of your fascia thwart appear to be sitting proud. The ones that are right next to it look really good with a nice dimple from the hammer head. Not to get too picky, ut it looks like you will need to make a trip around that hull with the clinching iron.
 
Thank you for your detailed explanation. I took a rather long vacation recently, but I will now start trying canvas on this canoe. If I use canvas, what kind of paint should I choose for the exterior?
 
Some progress. Thwarts are rough shaped:

Seat frame components rough shaped as well to mimic the thwarts; note in the third picture below, the cross rails will be 3/8" Oak dowels rather than 3/4"x1 1/2" stretchers one normally sees, and the holes for these have been drilled. I am going to go with the woven cane seat shown here:

Decks are installed:

And, at Mike's suggestion I have gone over the hull and done quite a bit more tack clinching, and now have 4 coats of gloss varnish in the interior. Once all varnishing is up to the same level, I'll make final coats with semi or satin to knock down the gloss a bit.
 
Tim, I have no doubt that you'll be able to dry bend your spruce inwales successfully, providing the grain structure is consistent. On my first attempt I used local spruce and had one side fail due to a spot of twisty grain. I suspected it might be problematic and, of course, it was! I decided to take no chances with the nicer Sitka spruce pieces I used on round 2.

I tapered my inwales to about 1/4" in width at the stem which I assume makes them more flexible, but at the same time perhaps more fragile.

Can you tell me the cross sectional dimensions of your rails, and if they are beveled or square on the inside faces?

Thanks very much.
 
And a matching bevel on the outwale, right? It looks to me from the lines and offsets in the book that the bevel averages out to about 1/16th from plumb. Is that in the ballpark?
 
Grab handles, thwarts, and seat frames varnished:

and installed (though not seats- they need to be woven):

Grab handles are radiuses across their width, and lightly tapered at the ends resulting in a slight crown which mimics the crowned decks:

The exterior of the hull has received a coat of 50/50 varnish/thinner prior to going into the canvas:

And canvas stretched overnight before being loosened to allow the canoe to be dropped in:

Canoe in the canvas with two bundles of shingles (150 lbs) wrapped in large garbage bags to avoid getting granules in the canoe provide weight to press the canoe down into the fabric:

Over the last two weeks an old canoe found me! An acquaintance of mine who knows I like old canoes arranged for a friend of his to give me an Old Town canoe which the owner had decided to get rid of. Turns out via the serial number imprinted into the stems, it was delivered to Trenton, NJ in 1919, exactly one year to the day before my Dad was born! It's a 16' Heavy Water model (designed with a rounder bottom than the OTCA model, and therefore preferred at the time for river travel), in CS grade which refers to "common sense"- a less expensive canoe with Spruce seats, thwarts, decks, and rails rather than Mahogany. It's in really good shape for being 105 years old! Another project in waiting...

Looking good, Patrick! I forgot to mention in an earlier post about sycamore - it is extremely prone to rot, so be sure to seal the end grain very well. Thwart ends, for example, often got no or little varnish in the old factories. Even with less rot-prone wood, I saturate end grain until it holds a surface film of varnish so the wood won't readily wick up water. Also, one of your posts mentions knot holes. How did you treat them? Best to avoid them altogether, but if they are there, what to do? Best would be to splice in wood rather than using any kind of filler compound that would likely be unsightly and could come loose at some point in the future. Maybe too late to discuss now, but food for thought. And by the way, that appears to be an exceptionally nice HW for its age. Enjoy!
 
Thanks Michael. I did soak the end grain of thwarts, seat frames, and grab handles. I filled the small knot holes with a two-part wood filler. Hopefully it will remain solid. I first scoured the perimeter of the holes to remove the tiny film of bark present in some of them. I had no choice... most of my planking stock was probably what Old Town would have called 'common sense'!

The HW is in amazing condition. The inwales have lots of holes from various seat and thwart combinations over the years, and one outwale has damage at each end, the other is fully intact. I haven't removed the canvas yet, but I see no evidence of any significant planking problems. Should be a fun one.
