I am at 180 hours on the build and the boat weighs 835 lbs.
Since my last update I have added another layer of fiberglass to the entire boat and 3 coats of epoxy filler. I had some issues with the epoxy fill coats, the epoxy I am using is 600cc viscosity. that’s very thin. It runs very badly . I discovered today after sanding off my runs from the 2nd coat, that if I used a 1/4” foam roller, I could roll it on thin enough that it did not run. It did leave a lot of bubbles in the epoxy. But I remembered something I read on a boat builder’s forum, that a hair dyer or heat gun would bust the bubbles. I was amazed at how quick and easy the bubbles disappeared. Just waving the gun over the epoxy at 10” from the surface and keeping it moving very fast took care of all the bubbles.
I do have a few runs on the transom but they will sand out easily tomorrow.
The second layer went on much like the first except I reversed the side on the bottom where the cloth overlapped to keep from having a ridge to have to fair.
After I wet out all of the second layer of fiberglass. I let it cure for two days then following a recommendation from Paul (shipwright), I sanded the epoxy that was sitting proud of the fiberglass weave smooth. This did away with the deep voids that would have taken a lot more epoxy to fill.
Here I am sanding off the epoxy. I am wearing the suit because I also am feathering the edges of the overlaps in the fiberglass. Also the epoxy is not finished curing. Uncured epoxy will finish curing where ever it is. In your eyes in your lungs. So I chose the suit and full face respirator for my safety.
Here is a close up of what I was sanding.
Here is what the boat looks like with 3 coats of epoxy fill. I only used 1/2 gallon of epoxy on all three coats.
Next I sand the epoxy smooth, Use System 3 Quick Fair to fill in any low spots, sand again then paint. I will update again after the paint job.
Thanks for looking.
