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 ...

Re: 17' 0" Freedom

Called it quits on this one Saturday. Ready to get on with finishing the 2nd composite hull from the same original hull. I hope to drop some weight on the next one (thinner foam, lighter gunwales, seats, yoke).... I registered with the US Coast Guard as a boat manufacture so I can assign my own Hull...

Re: Alternative finishes?

They say it can be recoated in 10 minutes but I can't imagine that working with anything other than spraying. I was a little to early a couple times and left too many brush marks for my tastes. Which is why I let it set a week and sanded. I'm really tempted to gear up (and learn how) to spray for my...

Re: Alternative finishes?

Oh and I did use a foam brush. But I bet it would work really well with a sprayer....

And no double posts for me....

Re: Alternative finishes?

The finish was hard to sand means I went through a ton of sanding disks to smooth it. It didn't gum. it was really hard. Not sure where the double posts are coming from. We upgraded the system to address a problem where we were seeing up to 50 new account requests per day... It was really annoying. ...

Re: Alternative finishes?

Here's a preliminary update on this stuff.... My test piece of plywood coated with well cured epoxy and just one coat of this finish left to cure for 24 hours and then soaked over night in water caused the finish to form tiny blisters and turn a bit whitish. So, extreme abuse doesn't work (it's supp...

Re: 2 1/2 coats of epoxy and glass successful; questions on next coat

I use a 3" wide brush for all of my coats (squeegee only the first 2). Final coat is always a bit rough but is easily sanded smooth before varnish. Just make sure you have enough epoxy on the boat to bury the weave of the glass so you don't hit the weave when you sand. I've never used a metal g...

removing oil spots?

I riveted my aluminum gunwales on my kevlar/carbon/glass canoe last weekend. I used a brand new pneumatic rivet tool to put them in (I'll never squeeze a pop-rivet tool again!). After I did the first 8 rivets, I noticed that the tool was venting it's blast of air out the front/bottom of the tool (ri...
