First Canoe

[WoodsNWaters]

I was going to make each strip long on one end and short on the other but figured it makes every strip fussy. Seems easier to make one strip short at both ends then add the long strip on the other side. Alternating sides, of course. I stapled one strip but haven't cut the ends yet.

My thinking above was wrong. Now I have to get the short strip -- the first of the pair -- cut to exact length for the entire canoe. After I glue the short strip down, there's really no chance to saw the bevel to match the long strip. The bead of that short strip is glued down into the cove of the previous strip and sawing down into a cove isn't gonna work*. Stapling appears to tighten everything up so the length of an unstapled strip is inexact.

I just read a post by @Gamma1214 about building "Raven". His method there was each strip had a short end which was beveled, and a long end which bypassed the opposite side's beveled end. Courses were swirled left then swirled right, left, right. (My words, not his.)

Re-do.

The Weldwood Professional Wood glue on the beveled ends of the first strip broke apart easily after a couple of hours. This saves the long strip but I'll need to scarf another full-length strip.

* A) Saw then X-acto-knife? B) Saw then Dremel? C) Glue and staple as far as the last lateral form then saw? D) Doesn't matter this boat is turning around. Each strip will have a short end and a long end.

You do what you gotta do to in order to make it make sense in your own head but it seems to me you are going about this about the hardest way possible.

Lay the first strip and let it run long. Use a pull saw, with the beveled stem as a guide, and cut the angle on the end of the first strip. Lay the second strip and let it run past the first strip. For your next course the short strip will be on the opposite side of the hull so it will alternate back and forth.

I'm hardly one to stick hard and fast to convention but that's generally how it's done and I've never seen a good reason to deviate.

Your method is what I decided I have to do.

With all the build threads available, I didn't see much about two bevels on one strip vs. one bevel per strip. That's why I mentioned the Raven thread which clearly explained it.

So far its only the first strip on each side. That's where I saw that long and short strips would be trouble later.

The one book I have that covers stemless builds puts 5 or 6 strips on one side then 5 or 6 on the other. I want to avoid that.

 

[Gamma1214]

I do it as Alan describes. Typically, the 1st strip is the hardest but it's not critical since it'll be hidden under the gunwales anyway. I use a scrap piece to check my angle before gluing it down.

I ended up moving only two forms. The battens and the straight-edge were valuable in different ways for finding and measuring the problems.

USPS delivered two glues yesterday: Titebond Extend Wood Glue and Titebond II Extend Wood Glue. TB E says do not use below 40F while TB II E says do not use below 60F. After mid-November, the basement won't have heat which usually means 50F (10C) into April. I can start heating some in March but not a lot and don't expect fast results.

I don't have any wood glues that make any claims for gap filling. Seems like the stemless ends of the first two strips are where I'd need that most. Or maybe I just need to spend more time cutting the angle right.

I found that using the stemless method created some gaps and such as well, I ended up just doing my best and cleaned it up at the end.

There were a few gaps, a few tears and I ended up waiting till the end when I usually go around fixing imperfections, for the stemless areas I just filled (before any cleanup) with colour matched, thickened eopxy .... followed by routine shaping directly (green) after it setup. The flaws just seem to disappear.

Somewhere I have before and after closeup pictures of one of my stems that had bigger gaps than Cletus's smile and you really can't tell at all after filling with thickened epoxy and shaping. I don't have the time to dig for them now, maybe later.

Here is my very simple method. It works great !

The strip below the top strip is on. (Strip above the top strip on the forms.) The first piece surprised me with how much squeeze-out came from such a small bead of glue. The piece butted to that was tidier but left me wondering if there was enough glue. The rest of this layer has occasional squeeze-out.

A putty knife chipped off blobs of squeeze-out easily after an hour or so. This is Titebond II Extend because I figured I'd be futzing with it.

I removed two staples to adjust the bead tighter into the cove and re-stapled. The end bevels are better on the second course than on the first. And easier with more visual clues to the various angles.

I was also surprised at how much the two layers of cedar can bow away from each other within the foot between forms. I wrapped in masking tape but will look for small clamps to make something like "Jimmy" clamps.



I need to be more careful selecting strips. Only after I was done did I notice that a section was flush on the outside but not on the inside. One piece was thinner. It has saw marks and I decided to put them on the inside of the boat. I should have realized it would be thinner. My measure of the first strip is 0.251". Most of this new piece is full thickness but 3' of it in the middle taper down to 0.211".

The difference of 0.040" is slightly more than 1 mm. I have the technology to fill this space with cedar but probably won't.

Looking down on the cove of the thinner strip and the in-focus cove of the thicker strip.



Looking at the inside surface of the two strips. I should have realized.



The darker strips you see on some annular rings are burn. They sand off. IDK if they will sand off evenly or not. They are often just a few feet long on an 8' piece.

Thanks. I've seen your great Pearl thread.

While it tells how you dealt with each end, it doesn't tell how the two ends of any one strip are treated. Or maybe it does if the word "alternating ends" has more scope than I think you intended but not as much scope as it possibly could. @Gamma1214 recognizes that writing precisely and clearly about these is work.

I quickly saw the error of a strip with two bevels paired with a strip with none. But not everyone really read that post.

I have tried both the chainsaw file and rat-tail file. I prefer a rat-tail such as the one you use. The results are similar but the coarser teeth work faster and leave a smooth-enough cross-cove. These two files are the same diameter (which is larger diameter than my chainsaws).

Searching for such a thing is beyond my abilities. The vocabulary turns up in more threads that have nothing to do with stemless builds, let alone stemless builds with interleaved strips. I could page through all the builds to see which are which . . .

Using an inner stem. You are gluing the strip to the inner stem, as well as the strip on the other side.
I start with one on one side, two on the other.

From there it's two strips to a side. One runs past the end, and gets notched. The other trimmed, to match the bevel on your inner stem. Then switch sides

Sorry for the confusion ! I should have paid more attention to the Teacher in English class !

Seems everyone has their own method ! Hope you find one that works !

Glue squeeze out, is more of an issue, when you get to the inside. I have cursed myself several times, until I decided to minimalize my glue !

I like any obvious saw marks on a strip on the exterior.
Much easier to sand off.

It's stemless. The forms are for a build with stems so I added stems to the form. I am not gluing to the stems.

Your description includes the noun "strip" then in the next two sentences the nouns are "one" and "other". Substituting a more concrete noun we get: "one strip runs past the end and gets notched. The other strip (gets) trimmed." Looks like long strips and short strips to me. You may be referring to ends, but didn't really write that.

For a clear explanation of both ends of each strip, please see what @Gamma1214 wrote about the Raven build here.

I'll note that the same page about Raven has multiple areas of re-work and no comments on it at all. I removed one strip, scarfed on a bit more, and re-stapled it and I'm "going about this about the hardest way possible".

@Fourbtgait
Thank you. That is useful.
