Cooper-I was trying to explain to "bigford" how vacuum bagging works. I know what you are doing but I have no experience with de-gassing the resin or rubber. I have quite a bit of experience with open mold vacuum bagging (boat molds) and am quite familiar with that. I think what you are doing would be closed mold casting because you are putting-2-mold halves together and pouring a tire. And I could be wrong but I don't think vacuuming could be used in any way with this system. If so it is waaay over my head!! I like the k.i.s.s. method.
