Development of the "combined-refit" type hurricane bow has begun with impressioning of the original, still in-progress prototype:
Note most of the bow is not immersed but instead liberally coated with RTV; repeated such applications will rapidly build up a thick, firm mold surface even before obtaining sufficient rubber to completely submerge the entire bow. At the same time, note all drips/runoff are captured in a temporary container (left); already creating a solid base (right) for the mold.
Eventually, the above aproach will allow for the remainder of a mold to be created by "back-filling" with lower-cost material - for example, cut-up chunks of old molds - essentially reducing the cost of materials for this mold to near zero! In this way, both time and materials are saved to enable starting more products development, sooner.
Cheers,
