Re: Attaching middle thwart with a mortise and tenon

I have always attached my thwarts with just epoxy and level with the gunwales. Rather than a beefy mortise and tenon joint, I use biscuits (as in biscuit joiner). They are quite strong and don't take much space.

Re: A couple of new paddles for 2019

Nice work Brian. And as usual some new good ideas in there. Thanks for taking the time to document the process so well. You're a gem! What was the final weight of your paddle? Here's a couple pics of the kayak paddle I recently finished.... https://scontent.feau1-1.fna.fbcdn.net/v/t1.0-9/52350939_10...

Re: 17' 0" Freedom

Well I've made some more progress on this build. I added flotation chambers, built some seats, skid plates and a yoke. All are installed and it's now ready for finish (inside still needs a good sanding. Current weight is 45.1 pounds. Sanding and finish might add a pound or two. A few pics: https://s...

Re: Thwart ideas?

I recently built some thwarts out of foam inside a sleeve of carbon fiber saturated with epoxy and installed with epoxy thickened with carbosil and graphite power to match the color of the carbon fiber. Super light. You could adjust stiffness by thickness of your carbon fiber and dimensions of your ...

These corrections are against the 2000 version of the book (as stated on the page).

Re: Stem template and canoe length

Hi, I don't have my copy of Canoecraft with me but I thought stem dimensions were included with all the plans. As for shortening the canoe, it is indeed possible by simply shortening the distance between each station. You would also likely need to shorten the stem mold to ensure a fair curve from th...

Re: 17' 0" Freedom

My math says it will be just on the border of needing flotation so I will probably add a couple small ones (foam covered with kevlar).

Re: 17' 0" Freedom

1/8" foam at 1 pound is consistent with my experience (2 pounds for 2 layers of 1/8" foam). But the epoxy added to glue it in place was no trivial.

Re: 17' 0" Freedom

Gunwales weight first. I weighed the boat this weekend after adding a filet between the gunwale and the hull (inside and out). The gunwales added a total of 3 pounds to the weight. Compared with the 7 pounds my aluminum gunwales weighed on the previous version I guess it's fairly decent. It was a lo...

Re: 17' 0" Freedom

Jim, The foam sheathed in carbon fiber gunwales were pretty flexible. They pretty much just stayed where I put them. I applied them with thickened (and blackened) epoxy in the narrow slot. But just to be safe, I laid the forms for the original hull across the gunwales and put a bit of weight on them...
