We ordered from a model builder a 3D printed positive form of the keel bulb in styrofoam. Christian has doubled it up by 3cm to create enough space for the shrinkage during the casting process. The styrofoam model was covered with 2 layers of epoxy to get a smooth surface. Christian built a box with the external dimensions H 24 cm, W 40 cm, L 105 cm. He cemented the bulb model with steel reinforcements.&nbsp; Small bubbles and bumps in the cement surface cannot be avoided. Thus the negative mould was smoothed with a thin plaster layer and sanding. The cemented form has to dry in the shed for a few weeks so that it loses moisture. Christian built 2 moulds because we had no experience whether the mould break and in addition to speed up the casting process.<\/p>\n\n\n\n<p>Many thanks Christian CG #103! Awesome job!<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"519\" src=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-1024x519.jpg\" alt=\"\" class=\"wp-image-145\" srcset=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-1024x519.jpg 1024w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-300x152.jpg 300w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-768x389.jpg 768w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-1536x779.jpg 1536w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-2048x1038.jpg 2048w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7499-624x316.jpg 624w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"596\" src=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-2-1024x596.jpg\" alt=\"\" class=\"wp-image-146\" srcset=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-2-1024x596.jpg 1024w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-2-300x175.jpg 300w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-2-768x447.jpg 768w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-2-624x363.jpg 624w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-2.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"539\" src=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-5-1024x539.jpg\" alt=\"\" class=\"wp-image-148\" srcset=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-5-1024x539.jpg 1024w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-5-300x158.jpg 300w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-5-768x405.jpg 768w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-5-624x329.jpg 624w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-5.jpg 1198w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-4-1-768x1024.jpg\" alt=\"\" class=\"wp-image-149\" srcset=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-4-1-768x1024.jpg 768w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-4-1-225x300.jpg 225w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-4-1-624x832.jpg 624w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/PNG-Bild-4-1.jpg 960w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"508\" src=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-1024x508.jpg\" alt=\"\" class=\"wp-image-150\" srcset=\"https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-1024x508.jpg 1024w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-300x149.jpg 300w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-768x381.jpg 768w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-1536x762.jpg 1536w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-2048x1015.jpg 2048w, https:\/\/minisailer.ch\/wp-content\/uploads\/2022\/08\/IMG_7552-624x309.jpg 624w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Christian CG #103 took care of the construction of the mould.
