Re: cane seats 2

What I can see looks very good, but for some reason while it says there should be 65 images, the highest numbered one it will deign to show me is 48.

Re: To Double layer the bottom ?

How strong it is, how much epoxy it takes, and how heavy the canoe winds up are all related. When you apply epoxy to the glass, it soaks in and makes an uneven layer. Canoecraft explains the best way to fill the weave using extra layers of epoxy, then sand down to a smooth surface without cutting th...

Re: Quarter-sawn boards suggestions

I think the reason most use quartersawn strips is simply that they are cut from flatsawn planks that are usually cheaper than quartersawn.

Re: How light could it be?

One of the most effective ways to minimize weight without sacrifice of strength is to wetout the glass with epoxy, then to cover the wet surface with a plastic film and roll it smooth. After cure, the film is peeled off leaving a smooth surface that needs no fill-in coats. It can be sanded with 360 ...

Re: Interior Hull filled with water before fiberglass

Ouch. Swelling of the wood causes the hull to buckle, since the glass does not. Heating the wood to dry it thoroughly might shrink it enough to minimize the problem. A bright incandescent lamp may be enough. That happened to me a long time ago (1972?) and I dealt with it simply by glassing the insid...

Re: inwale and deck material question

If you want a lightweight, light colored wood, try spruce. Sitka spruce used to be the recommendation, but is harder to find. I have a canoe with spruce decks, seats, and gunwales. I think one outwale needs attention, but the boat is almost 40 years old now.

Re: Vertical stripes

It's hard to be sure, but sounds like what can happen if you don't maintain a wet edge. As you apply epoxy, it soaks into the cloth and to some extent, the wood. At the edge where the cloth is wet by epoxy, as it spreads into the dry cloth it thins out and covers less well. As long as you continue a...

Re: Help with webbed seats

My temporary webbed seats have lasted almost 40 years so far. I didn't use stainless, but I think I used screws rather than staples. I will need to replace them soon, but it's the webbing itself that's deteriorating.

Re: Low angle block plane or Spokeshave

I also would start with the plane, and don't think it needs to be low angle. A spokeshave is useful for paddles, but does not seem to me to be needed for the curves of a canoe hull. A card scraper is also a wonderfully simple and useful tool: get one. I have found that some cedar boards scrape beaut...

Re: Ammonia/water wash before varnish ? WHY

The ammonia wash is a good idea if you have blush. The reason is that epoxy hardeners are amines, which are basic. Exposure to water and CO2 can convert them to their bicarbonate salts, which are water soluble if small enough molecules. This part you can wash away with plain water. But some of the a...

Re: My hull is warped

It sounds as if it's now less humid than it was when you put the glass on. The glass/epoxy does not expand and contract with moisture, but the wood expands sideways to the grain as it takes up moisture, and shrinks as it loses it, but does not change significantly along the grain direction. This cou...

I scarfed using the A orientation with epoxy, which helped the joints to blend in because it's transparent and will cover all anyway. The thin edge helps. Some of the joints are hidden to the extent that they are hard to find even if you know where to look. Some (where I did a less good job of color...
