Re: Great Dane excavating co.
Oh ok, I did not know about pulling a vacuume on the mold when casting. I am not planing on doing that. I got the pump to pull a vacuume on the materials before casting. To de gas the mold resin and casting resin after mixing but before pouring. I always thought that was more for carbon cloth or fiberglass mold forms, rigid stuff with vacuume bagging. Not casting stuff. The process I'm doing is something other than vacuume casting. I think it's called open mold casting.
