H.M.S. Sovereign of the seas

I have started on a wood model of the H.M.S. Sovereign of the seas that I will use as a plug for a fiberglass hull.

here are some pics.

I have almost completed the plug (I went with foam instead of wood) any suggestions on how to make the mold would be appreciated thank you.

here are some pics.

The mold is done I made it out of fiberglass and more Bondo.

I have got the lead for the drop keel a few days ago from a friend that races cars. He uses the lead to ballast his cars.

the hull is almost done I need to make the drop keel, quarter galleries and paint it. I have estimated that I would need approximately four pounds of lead in the drop keel about ten cubic inches or 150 cubic centimeters.
