Seems like an inexpensive way to de-air a casting, but it does not specify how much of a vacuum it creates, too little, and the bubbles won't burst, they'll just get larger.


I used a Food Saver http://www.amazon.com/FoodSaver-Advanced-Design-Vacuum-Packaging-System/dp/B000AAYD6W/ref=sr_1_4?s=home-garden&ie=UTF8&qid=1338299867&sr=1-4  because we own one and use it to seal canning jars, food bags, etc. and it has separate containers that can also be sealed.
I am new to this and just used it to de-air the RTV and the resin (before pouring).   Worked fine.   I may try it on the actual casting after my new masters get here from Shapeways.
:cool:
