What type of mold to use for a prop style blades
Posted: Fri Mar 20, 2015 6:45 pmtrying to figure out what the best mold would be for a prop style blade thanks
Either two piece, or easier a squish mold made of high strength 3. Totally bury your master, (don't forget to put in a steel pin coated with mold release)let the rubber cure, cut a slit, pull the pin, pull out master. Coat pin with mold release, Reinsert pin, mix resin, pry lips of mold open and pour!
Be sure to allow enough blade thickness that the resin you choose is strong enough to do the job for the blade size you are choosing.
good luck,
