SteveM | 19-Feb-08 22:07 | The mold halves. The one on the right came out great but the one on the left has air bubble issues. |
SteveM | 19-Feb-08 22:13 | The left half was made with the cowl suspended while I poured rubber into the area under it. As the rubber level rose air got trapped. The most obvious is the jelly-bean shaped hole next to the cylinder. The one that is difficult to see are the two circles down in the bottom of the mold are not solid as air bubbles were stuck in the holes on the front of the cowl. You can't really see, but a plethora of tiny bubbles rests just under the surface of the rubber. Had there not been a cowl in the way they would have been able to escape to the surface.
Moral of the story - I should have poured the left mold so the rubber was on top so gravity could help me. Klean Klay to the rescue! |
