Re: Stem template and canoe length

Hmmm that's odd. I just cut and pasted the link...

Try this one: http://web.archive.org/web/201211081136 ... estems.htm

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

Thanks

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...

Re: 17' 0" Freedom

I cut the groove in the foam first and then put the carbon fiber sleeve over it and poked the sleeve into the slot. I put the combination of sleeve and foam on the hull edge over a layer of saran wrap and then wet out the fiber and the foam. This allowed me to make sure the foam and carbon fiber cur...

Re: 17' 0" Freedom

I decided to experiment a bit with lighter gunwales. I ended up with a foam core inside a carbon fiber sleeve. https://scontent.feau1-1.fna.fbcdn.net/v/t1.0-9/45325079_10156259819407885_5549973009227317248_n.jpg?_nc_cat=110&_nc_ht=scontent.feau1-1.fna&oh=527cfd2f5166a087767a91c58a54f064&oe=5C706423 ...

Re: Treatment of inner stems before glass?

I round over the edges of the inner stems before I start stripping (just the edges that won't be covered by strips.

Re: 17' 0" Freedom

Here's a peak at the 2nd one. Two layers of 1/8" thick foam with no ribs and 2.2 Oz Kevlar inside.

Re: 17' 0" Freedom

Thanks Jim, I had seen the first two threads but not the last one you posted. That third one used the same foam I'm using. I used 3/8" thick 4 lb/CF foam for the first build. The 2nd hull just got a layer of 1/8" foam yesterday (3 lb/CF). The problem with this foam is that is sucks up the epoxy as q...

Re: 17' 0" Freedom

I haven't weighed the cedar hull but low 50's sounds reasonable for a final weight. I'm hoping to get the 2nd composite version below 50 (45 would be a win for me). I'm looking at a carbon fiber sleeve around a piece of white cedar or maybe foam to create a uniwale for gunwales. Seats and yoke can b...

Re: 17' 0" Freedom

The gunwales are aluminum from Wenonah. I was amazed how heavy they are (7 pounds). Thwart / hand holds are black anodized aluminum tubing from Savage River canoe works. Seats from Edscanoe.com (also quite heavy). Yoke and pads from a local paddle shop but I think they sourced from Eds as well). It ...
