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...

Re: Alternative finishes?

I put of a layer of this down on a scrap of epoxy coated plywood last night. It cured nicely over night. I'll dip it in water and see what delaminates first.

Re: Alternative finishes?

I'll let you know what I think. I have a gallon in hand (it came from Ontario I think).
The price was definitely right.

Alternative finishes?

Hey, I've always used Epifanes varnish for my cedar canoes. Like it. Just finishing up a kevlar/carbon/glass canoe... Looking for a more clear UV inhibiting finish. Has anyone used this stuff? https://theepoxyexperts.com/shop/coatings/max-seal-1-gallon-protective-clear-coat-aliphatic-polyurethane-no...

Re: 17' 0" Freedom

Got all the foam "installed" into one of the composite hulls last Saturday and put on the last layer of Kevlar on Sunday. Wetting out the kevlar was quite an experience. For every foot of linear distance down the centerline, the sides needed to consume about 13" of kevlar (due to the curve of the hu...
