Glassed Rear Transom


Yesterday we glassed the rear transom. After we glass the front transom (which we plan to do next weekend), we'll be done glassing the exterior. Then comes the fairing.

We've gotten pretty good at laying glass, and have devised a method that lets us lay two layers at once. The first time we did it was a little tough, but through a little trial and error, we've got it down to a science. By doing two layers at once we are saving time and I think we'll have a stronger boat, because laying two layers at once will give us a single chemical bond in addition to the physical bond. It also seems to cut down on the amount of sanding we need to do.



Here's a picture of the glassed side (which we did last week). We glassed the side using the aforementioned both-layers-at-once method, and I'm quite pleased with the results. Glassing the side took us about four hours using this method, and the rear transom took about two hours.

Our double layer method consists of measuring the glass cloth and laying them in place, and laying a coat of epoxy thick enough to saturate both layers of glass. The horizontal surfaces are very easy, but the vertical surfaces are a little more tricky. We've found that it's best to use a roller to work a thick layer of epoxy into the glass at the top, and then slowly squeegee the excess down the side. Make sure to do this very slowly, so the epoxy has a chance to saturate the cloth as you go down. If the epoxy is rolling down the surface as you use the squeegee, you're moving too quickly.

One note: I do NOT recommend doing this double-layer method unless you've got two people for the task.
