Made some progress yesterday...
The Florida heat and humidity were not as oppressive yesterday so I got some things done.
The first picture is a template I had made previously for the fiberglass bulkhead I wanted to stiffen up the keel with. The bulkhead was 2-1/2" wide at the bottom and 6" wide at the top. It was 18" tall. The bulkhead was made from 6 layers of 1708 biax and after it kicked I used my pattern to mark the size and cut it out on the bandsaw.
The second picture is the bulkhead installed with just the fillets.
The third picture is after I tabbed it in. The dark line down the center is a refferance line I drew on the bulkhed with a dry marker to help me line up the biax tabbing when I was putting it in. I left about 1 inch under the bulkhead so water can travel back and forth under it.
The forth picture is what the aft end of the ballast looked like after I had cut the fiberglass out that enclosed the foam the factory installed. You can see at the point where I stopped cutting out old glass that there is about 1-1/2" of foam between the glass and the lead ballast. I had to transision down from there to the top of the lead so I made a pattern of the area and marked and cut out the biax to the shape I needed. then I wet out a portion of the biax in the area where it needed to make that transision and let it cure on the bench. Then when I installed the glass in the boat this created a ramp down from the higher level to the top of the lead.
You can see the glass installed in the fifth picture. Following Ebb's advice I left the very end of the lead ballast open so any water getting into the keel forward of that point would have an escape route to the bilge.
Ebb and anyone else with thoughts on the matter...
I have to say the added bulkhead makes a hugh differance in the rigidness of the aft end of the keel. But another added bulkhead above the aft end of the main ballast and biax tying that one to the other one I already installed would make the area incredibly strong. I will have to take a serious look at that.
Another issue I have and I don't know if the Boat came out of the mold that way or if the Vermont freeze thaw cycles caused it with the wet foam in the keel. But I have some humps in the port side of the keel in the area where I took all the foam out. I've sanded off the filler the boat yard had put on the keel in that area and it is not a repair or anything like that. It is the original fiberglass that makes the humps. Since this is also the area where the boat yard had sanded through the gelcoat I figured I would finish sanding of the gelcoat in that area so the epoxy would adhear better and fair the hull with some epoxy and microballons then after fairing it out apply the layer of 6oz cloth over the epoxy filler and and finally fair that out before I redid the barrier coat and bottom paint.
Opinions on my plans are welcome.

OK maybe it is more appropiate to call them low spots...
Because as I taped this 5 foot long metal rule to the hull it looks like the high points should be the fair line of the hull and the low spots make the high points look like humps.
I can tell you with certainty that there is only one spot with a repair to the fiberglass and you can see that spot in the first picture. I am intimate with the inside and outside of the hull in this area after all the time I have spent working on it and the laminate is original and solid. I am the first person to see the inside of the keel since it left the factory full of foam and glassed over.
The starboard side is fine. It has fair lines and looks like it should.
