Inside Bullkhead of Port Fuel Tank

Chad and I were able to layup the inside bulkhead of the port fuel tank this morning in 2-1/2 hours,
record time. It sure was a lot faster and easier with his help. This finished product came out much flatter than the first one did. I had trouble getting the joints in the glass work to layout flat before the resin kicked. There was just too much glass to work to get it done in time. Went much better today with his help. I had him wetting out the glass while I worked the air out off it and laid more pieces in.


My ideas for the mold worked out well too. This is the bulkhead with the sides of the mold removed. The glass came away from the masking tape OK and the tape came off the wood easily as well, so there was a backup for when the glass stuck to the tape.
The Dark areas you see are the joints in the top layer of glass. The layers overlap where the vertical sections meet the bottom and top cords. There are 4 laminates of 24 oz Combomat and 1 layer of core mat in the middle. Really a bit of overkill considering that each section will be glassed to either the hull, one of the other sides of the tank or a baffle which goes in the middle of each tank. But I wanted the thickness to get some stiffness around the edges of the inspection ports so the gaskets will seal.

I finished glassing the forward and  middle bulkheads in as well. So I am ready to glass the inside bulkhead in when I have it ready. My next step will be to clean it up around the opening then drill all the holes for the bolts to hold the covers in. With any luck I should have the inside bulkhead glassed in by the end of next week.
