Clamps... I use large pvc pipe to make simple clamps. Cut into rings, then slit the ring open so it looks like a pac man mouth. The thicker the ring, the stronger the clamp. Very cheap and useful.
What if you're building a flat water canoe and want a flat sheer because you're not worried about high waves or rocker. what do you do about asymmetric sag? Modern flat water canoes are asymmetric.
You mention a guide boat- do you have a class or plans for building one of those? I have some 18’ pine boards that were part of a roofing material bundle and I’m hoping to use them to make a skin boat. I still haven’t decided what to build, yet. And I have some other projects to finish first. But that is on my radar, if it’s what I think it is!
The guide boat is a pretty challenging project not at all easy like the rest of what I do. I thought about putting together a plan but I’m not sure I could justify the time that would have to go into it. What I’ve been doing for people that inquire is I have a really long text document that I give away for free. Basically all you’re doing is building a traditional Adirondack guide boat but at the point where you would normally plank it you stringer it and skin it instead. Happy to share what I know with you. Feel free to send me an email.
Thanks! I had noticed your laminated gunwales in other videos and wondered about them. 1 question: how do you determine how much curve you should build in with the lamination? As you explained, the angle outward already produces some of the sheer. Therefore, this curve is less than the sheer specified in a design.
Thanks, Brian. May I ask a silly question? Cutting out mortises in absence of router may be tedious. Now, if one is laminating wood for gunwales, would it be practically saving time and effort to use cutouts in the middle part spaced out accordingly. After laminating you end up with 'prefabricated' mortises. Should beat chiseling.
Sorry, Brian. My fault. I can't express my idea as clearly as you do. I find your presentation and explanations to be the best on internet. Anyway, I will try again. Let's say we want to use laminated gunwales. Say, we use three layers 1/4 by 2 by 16 ft. Now, before gluing, from the middle strip, we cut out 1 and 1/8 long and 1/2 in deep rectangular recesses spaced 6 in. When we glue three strips together these cutouts will be ready mortises.
It's an interesting idea, but I think the time involved and glue squeeze out would drive you nuts. Maybe it would work with some form of PVA glue. or if you put lubricated chunks of wood in the spaces, but then you'd still have to take that lamination and add another lamination to make the curved sheer, and thats a LOT of laminations! :)
Hey Justin, for kayak gunwales I usually go 11/16 x 2 1/2 or 2 1/4, in cedar, 5/8 in spruce or pine. However for gunwales this tall, I would go 11/16 with either wood. The cedar might benefit from being 3/4 actually, but that's cutting it pretty close.
That is for kayaks though, for the canoes I'm building things would be determined by whatever creates an equivalent flex so the frame stays in balanced tension and still nests. I'm not sure what those numbers are yet. After these prototypes I'll need to make one out of pine to figure that out. In an ideal world I could just sag a board with a specific weight and measure deflection, but unfortunately you can't do that with a curved board!
Love your vids man! I run a furniture shop (chasewarrendesign.com). Going to have to follow your lead and make a few of these. From the standpoint of a woodworker and outdoorsguy who doesn’t know a ton about boats- your channel is the best info I’ve come across and you have all the same criteria that I would want in a lightweight canoe
Big heart for the passion!!

I really like your videos.

Thanks for that. Great tips! Can you share what thickness you end up with for say WRC versus Spruce?

Great video and great information, thanks a lot ...:)
it will be a catinary curve not an arc
