Bottom wing mold cut.
After being away from this for a bit due to vacation and then work... am back at it. Decided to cut molds for tail surfaces out of corian, as there was no point doing plugs then molds.. let's just skip a step.
Have horizontal parts done, polished, waxed, painted.. when that cures will lay up the halves.
Woo-hoo I was waiting.

First I had to cut out a template for the horizontal shape, for material. I should actually make another that has holes where the dimples are so I don't have to do that by hand, or can at least mark them to cut. Also one for the balsa used because it does't go the full width of the part.
Then I cut out light glass for the layer against the paint, so hopefully there is no print through. Then glass, carbon, balsa, and last layer of glass. Some kevlar for the hinge line.
Wet it all out, placed in the mold's, working out bubbles and getting it lined up as best I could. Then two layers of peel ply (because the first test I could not get it off the part without popping the part out of the mold), and I don't have any perferated plastic.. need to order some. So hopefully this one will peel off better. Covered with paper towels, then into the bag.
Well, pulled from the bag, you can see it with one layer of peel and paper towels pulled off. The second layer of peel came off ok, without popping the part out of the mold, but gonna get some perf plastic to use as well.
The fluorescent paint used didn't work well, that's crossed off the list of possibilities. I think that was rustolium, will try krylon as well. The other sprays used work fine.
Out of the mold and trimmed up a bit. This one will just be used to mount on the fuse mold with some thickened epoxy to get the saddle for it to the perfect shape.
So I dug the files out, and picked up some wing plugs we made for this . Now I am getting busy.
