I build a lot of skin on frame kayaks. I like them and they are easy to build. However at times I get sloppy and get some funny results. You builders out there may like this one. I had not built a boat for about a year and had some epoxy hanging around in the workshop. I figured," what the heck," and used it on a frame I had just finished. Generally I will build the frame using screws and then take it apart and glue and screw it back together all at once. I had completed the frame for a new boat and after the epoxy set I took out all the screws, and went to work on something else. My back was to the boat and I heard a loud POP. I turned just in time to see one of the ribs begin to pop off. Then another pop, then pop, pop, pop, pop, and the entire boat, in a span of no more then 5 minutes, disintegrated into a pile of sticks on the floor. It was the closes thing to a cartoon I have ever seen in real life. I laughed for an hour. My only regret was I did not have the video camera in the workshop to record it. I sanded the joints bought some uncontaminated epoxy and it is a nice boat with a funny story hidden in it now.
