I have a carbon fiber seat and thwart that I’m going to use to make a yoke. I have fiberglass resin with the hardener and enough matching carbon fiber fabric for the project and am curious if anyone has any experience along this line.

The seat is from a Northstar canoe so I’m pretty sure it has a vinyl-ester outer layer(can’t remember). I haven’t thought much about my final design, but I know I’m going to have angled pieces flush with the seat frame piece. I will also want to wrap 2 pieces together on top of each other for extensions to get the length I need. And of course the parts will get a good sanding(? grit anyone).

I’m not worried about maximizing strength because it won’t have to support more than 25 or 26 pounds. The bulge visible on the seat frame is the reason that I have the opportunity. That and the incredibly good customer service at NorthStar-they had never had a piece fail like this.

It started to fail on a trip out of LIS N and supported me just fine I realized the problem. I can sit on it now, and that fail-point might provide some flex. I took it off at that time so it wouldn’t affect the gunwales. In that short trip across the lake it bent the bolts at about a 10 degree angle.

I know I could just spend the money for the right resin, but the point is function and the yoke won’t be visible to anyone but me 99% of the time. And if you looked at my last Kevlar repair, you’d recommend someone do the job for me anyway. I never checked, but my son was going to buy me a yoke for Christmas but he said it was hundreds of dollars.

Thanks, Fritty
