25. Status Report

So, the past three posts catch us up to today. I have started bending the laminate strips for the next outer stem. After I finish installing both stems I will start on the gunwales. I had hoped to be in the water in May, or at least June, but I can see the conclusion approach now, and take heart from it.

This project has never been a chore. When I'm thinking about what I want to do with the next chunk of free time that comes my way, it is common for me to look forward to spending it on the canoe.

24. Installing an Outer Stem

To prepare the surface for installation, I first sawed, then planed the strips flush with the inner stem. Then I cut a rabbet (stop line) with a pull saw, and chiseled to that line. (not shown below, sorry)

I used way too many screws installing the outer stem, but they were brass and so shiny.. anyways, do you see where the outer stem stops? (in the picture below) That's where I cut the rabbet. (The outer stem is inset a bit)

In addition to the screws, I used a mix of epoxy and lots of wood flour between inner and outer stems. There was a small gap ( < 1/8 " ) and the thickened epoxy hides it.
I shaped the outer stem in place with a sanding drum attachment on my corded hand-drill.

When I was happy with the shape, I applied another layer of fiberglass and epoxy over the whole thing. Below, I have started to feather out (sand down) the new fiberglass. (The white dust is mostly epoxy dust) When I am happy with that the whole assembly will get another coat of epoxy.

23. Laminating an Outer Stem

As a guard, and a structural element, an outer stem covers the inner stem and the ends of the strips. Like the inner stem, I've laminated the outer stem from oak, except the outer stem is wider.

I've used waterproof polyurethane glue again, and as before, it's a bit messy. The glue drips come right of the floor easily, but I still should have laid something down.

I scraped the glue drips off ..

22. Fiberglass the Inside

Long time, no posts. I'll catch up a bit tonight. Here's the fiberglass cloth draped over the inside, ready for epoxy. I started pouring epoxy in the middle, and worked outward. It was more difficult to spread the epoxy on the inside than it had been on the outside. Puddles formed in the middle, and the area around the inner stems did not turn out as well as I'd like.
