Netters, Over the Thanksgiving Holiday, I started doing the layups for the forward and Turtledeck. I made a foam layup tool that is the outside shape of the turtledeck. Prior to doing the layup, My wife suggested that I use Frost King window film. This is the stuff that you can tape around the perimeter of a window, and then use a hairdryer to shrink the clear film taut around the window frame. So I looked at it and thought, this maybe exactly what I'm looking for. So we taped it down over the tool and shrunk the film over the foam tool. We then took some 8 mil visqueen and marked the trim lines for the fiberglass. We then did the tried and true method of reverse layups onto the visqueen, on the build table downstairs. Brought the layup back upstairs and positioned it onto the tool. We then squeegied out all or any air-bubbles and laid the Peel-ply over top of the layup. Michelle then took shears and cut the excess peelply in strips while I pulled any peelply wrinkles out. This technique is used by tailors and removed all wrinkles out of the complex curvature on the mold. I was especially happy of the results when we removed the turtledeck and forward deck parts. There are absolutely no areas that were resin poor, the parts popped right off of the foam tool with no damage to the part or the foam tool. So now that I have the Outside Moldline Shape or OML, next I will carve "hat-sections" into the foam tool, Duct-tape over the areas where the hats will be laid up, fabricate the hat layups, then lay the outside part over the hats and co-bond the assembly. This should yield a very, very light but stiff part.
