Varethane

With the inwales attached, the next step was to apply a coat of urethane.  We used the Minwax Helmsman Spar Urethane.  It's designed for marine applications. 


This took considerably longer then we were expecting (about 4 hours for a single coat).  We opted to take our time and put on a thin coat, as we both have an aversion to varnish drips.  We were sure to get all the lashing, underneath the stringers, and pretty much anywhere else.  We started with the frame upside down, worked our way from one end to the other, then flipped the boat and worked back again.

Once the first coat dried, we sanded the inwales.  The outwales were left rough, as they would be covered later on.  It's really difficult to sand everywhere.  The lashing makes this impractical.  With the first coat on dryed, we installed the breast hooks.  We mounted leftover pieces of stringer to the inwale with brass screws.  The screws were predrilled, and we used the below flexshaft on a cordless drill to drive them.


With that done, the breast hooks were sat in place.  Some minor adjustments were made with a rasp to the shape (unlike plywood, the angle of gunwales was not square).  There is a notch cut out near the stem on the front and back to make it easier to drain the boat.  The finished product was ok, but aestically, something about it bugs me.  I think it's that the sharp lines on the edge of the breast hook contrast too much with the rest of the organic lines of the boat.  We may shape this a bit more with our microplanes/dremel.


With the breast hooks done, we decided where the thwarts, yoke, and seats should go.  This was done mostly by looking at pics of other canoes, and actually taking the frame down and sitting in it.  The final layout might yet change.  But before we get to that stuff, we have to install the floor boards.  We gave them a coat of urethane and set them to dry to the right.

Inwale


The next step is to install the inwale.  The inwale give the gunwale a bit more structure.  We cut it to size, then used our microplane to shape the end so it would fit well between the filler and the plywood stem (no pics).

Then we glued the inwale and held it in place with clamps.


Then we used brass canoe nails from the inside.  They were a bit long.  Traditionally the process is called clinching nails.  Basically, the nails are designed to go all the way through, then bend back on themselves creating a staple effect:

With the inwale attached, we trimmed the excess off the ribs.

To smooth out the gunwale, we used a small plane.  There was a little bit of tearout on the far side of some of the ribs, but it was minor.


After the glue dried, we were a little unsure of how well the lashing would hold the entire gunwale on  to the stem, so we decided to put a brass screw in each side.  We carefully drilled a pilot hole, making the port side higher then the stern so our screws didn't collide.  Then very slowly, we put in the screws.  Worked like a charm.



Then we touched it up with an orbital sander.  A few more pics of the final product.
