<div dir="auto">Hi Sean, the inner half of the mold is cast against a layer of waxed tin foil for a fairly smooth finish. The first layup is chopped strand. The next 4 layers will be chopped strand , and then 2 layers of biaxial with a float coat of resin. Due to the complex shape, this should be strong enough for the inner wall. The exoskeleton on the other hand could be as many 8 layers of chop strand. The final top coat layers, will be determined on smoothness of the chop strand. We expect that the final thickness could be 3/8".<div dir="auto">David</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jul 6, 2019, 10:09 AM Sean T.

After putting up an umbrella for shade, i removed the first inner ballast tank wall made from fiberglass. I have at least 4 more to make. Next i stripped the ballast tank form work off the hull and proceeded to fit up sections of the wings and the tail cone sections. By the end of the day, 4 pieces were glued together and i started to rough shape the joints and fairing out the complex curves. Tomorrow if I'm lucky, meaning my wife lets me play with my submarine, i hope to add the next 4 ft section on the front around the forward pilot sail. Its all shaped on the keel jig in the shop ready to be moved onto the trailer. <div dir="auto">David</div></div>
