thank you that makes sense, but I found a u tube vid on this system that uses a vac pump and a bag just for stabilizing wood. they had blanks and bowls from small bags to very large bags. I've looked all over and cant find it now. in my search I found this site and thought that someone may know what I'm talking about
Great video. I see the overflow tank is a vital part of the system, and I think it can even be used as a reserve for the resin that can backflow into the bag if the wood absorbs all the resin in the bag.
