Thread: 12mR scale 1:12

    Default 12mR scale 1:12

    I'm currently building a 12mR Columbia, Americas Cup winner from 1958. When producing the plug, I altered the stern slightly, making the hull an additional 4 cm longer compared to the original.
    The original boat can still be built, by cutting the stern back to the original negative version.
    I'm posting some pictures to show the progress. 13.8kg, 30.4 pounds of lead, 178cm or 70 inches long. Mast hight will be 210cm.

    Walked in the rain today to test float the boat with the new keel I just poured.
    I still have some trimming to do on the lead. The boat sits a bit front heavy in the water.
    It is a good thing to have a prototype hull and lead to work with. I can fine tune and then hopefully get it right on the "real" boat.

    Well, One more trip to the Swan pond today for "tank" testing.
    I think I now got the lead shaped the way I want it. 14.2kg of lead and the hull floats very nicely.Click image for larger version

    Thin plaster cast submerged in dry sand in home made box. Works perfectly for casting lead keels.Click image for larger version

    The build is progressing. I will post new pictures later today. Been on a business trip this week, therefore not much progress on the build during the week.
