I needed to cast a lead keel for a model yacht I'm building so here's my first attempt. Happy with the results :-) Also new to movie making and editing Lol I guess it shows.
In college Bronz sculpting class we used.. Plaster, Vermiculite, Perlite, Tarpaper, and Wire mesh shell. The chicken wire/hardware wire was to hold it all together so it did not pop open dramatically. We also used a thin coating of silica sand to refine the surface of the negative. (Lost wax method). but that's a little expensive. Nice boat, I'm looking at building something traditional and elegant so I can lay inside. Probably about 11ft. Love scratch and builds. Nice looking boat.
I did the same thing with my keel, casted it from lead. I used molds made from casting plaster instead of lead. You have to let the molds completely dry, a couple of days, before pouring in the lead. You get a much smoother finish on the lead casting. Great video.
