Last week I made some glasson plywood keels for a “practice project”. I used an FCS “TF1” kind of turned inside out for my template, cut fins out of 1/4 marine ply. I liked the result of the shape and the foil, so I decided to make some for my son’s fish that were FCS compatible. I have made some before, but never really figured out a LEGITIMATE way of treating the tabs. I just cut them out with the planshape and glassed along with the rest. There is always a compromise when sanding the tabs to fit perfectly, and I have never been satisfied that they were sealed. I was thinking about soaking in cold resin for awhile then setting off with a few hot drops??? I am sure there are some other backyard freaks out there with some good ideas… help a brother out?
