Pics of the pump tunnel mold as promised ,also some pics of the Styrofoam flotation out of a donor TS.The pump tunnel mold was splashed off of a TS also,it is kind of strange but the TS has a smaller pump tunnel box area than an SX or X2. Thats wax on the first pics of the mold,on a new mold you want at least 10 coats of wax followed by PVA so the pull comes out clean plus I usually store the molds with a good coat of wax like that for protection.For those of you that don't exactly know what you are looking at the mold is a reverse mold of the inside of the pump tunnel,the mold is fixed into place in the ski,waxed,sprayed with PVA and then sprayed with gelcoat,after that you start laying the glass or in this case carbon fiber up against the gelcoat on the mold overlapping to the hull,when you are finished you seperate the mold from the new pump tunnel and voila! you have a new carbon fiber pump tunnel.
