A rather inauspicious start for my next project, a 16' Barto/Brady Melonseed. With the model done and the temps finally getting above frigid I made it to the shop and got 16 slices of 3/16" black locust cut for the stems. I brought them and the epoxy (West system w/205) into the basement (fairly constant 55) and gooped and clamped them.
I returned 2 days later and it looked pretty good, I unclamped and began to clean it up. I was feeling pretty happy getting the first part of the boat underway until I was just about done, of course, when the laminations gave up interest and starting going their own way!
I've never experienced epoxy failure before, and was glad that it happened now, rather than on the boat, would be even better if it never happened! Thinking that maybe the epoxy was cold soaked when I brought it to the basement, even though I gave it hot water bath, I cleaned up the veneers and reglued just the inner stem (6 lams) this time. Clamped it overnight (55 again) and in the morning it looked fine. Until I returned a couple of hours later to find this:
Can epoxy go bad, it had been cold soaked all winter? Did I not clamp it long enough for the 55 temp? Gougeon says problems can occur below 40 degrees with 205. Well, it was fun to start. Won't be quite as much to restart.
