The plans call for a fiberglass band all around the boat at the chine for strength and ding protection. I thought it would be a good chance to practice fiberglassing, since I have only done it twice. It turned out to be very tricky, so I’m glad we tried this out before the huge surfaces on the hull itself.
The band is 9-ounce fiberglass tape 8 inches wide. Very nice stuff with a good sharp edge from Defender Industries. But the usual technique of working with a plastic squeegee-spreader to move the epoxy around and force it down through the glass to the wood was very difficult on such narrow surfaces. I tended to catch the edges or flip epoxy all over the place, and finally used a brush, which is slow going and uses a lot of epoxy. Ray was working down on the flatter surfaces, and seemed to get the hang of the spreader right away, so did about two-thirds of the boat.
Friday I rolled on the fill coats with one minor disaster. It has been down in the teens here forever, and today is yet another blizzard. The shop was very cold when I came in, so I warmed up the epoxy a bit with a heat gun to get it to flow. But the back of the boat down by the steel doors was very cold when I put it the epoxy on and it got pretty thick. I left for lunch and a supply run, and as the furnace warmed up the shop, it warmed up the epoxy which ran into big gummy drips down the side of the boat while I was gone. Hours of sanding will be needed to take them out. During the major glassing, I will have to keep the shop warm all night and pay the piper.
We are using West 207 Clear Hardener which contains some chemicals that are a bit more aggressive than the regular stuff. So I figured out a way to put a flip-up ventilator in the door frame. Let’s in some cold, but in conjunction with the furnace and dust collector, a lot of air is moving through the shop.
I am enjoying your build! Can you tell me where to get a ventilator fan like that?

Good old Northern Tool — $219 plus shipping, and for the money it’s a really quality unit.

pay the piper,in the long run it’s cheaper to keep to keep your shop,”not cold” than to to heat not only your shop,but every thing in it,everything,drywall,bicycles,wood,I try to keep my shop at least 55f,its only 10f toworking temp,15f to epoxy,paint or finish temp,not 30+f to get to work,so pay it forward,away for a week or two,let it cool down,but take care of your paints,varnishes,resins and hardeners,they may be effected by the cold,more than your savings on heat,I know I get a lot more done in a day if I don’t have to wait for my shop to warm up,the boat is looking great,I see a roll-over coming soon!!!!
