Vacuum bagging

[tommy6]

Anybody here have experience vacuum bagging bows?
I was at Woodcraft and they had Roarrocket kits that include the bag and pump. Im going to laminate up a bowlimb and see how it works. Any help would be appreciated!

good question, I have never done it or seen it done, but think of the vac packing for food. Would it open up the wood grain and make the wood absorb the glue deeper into itself making a dry joint? or would it allow air trapped in the wood fibers escape and be trapped under the glass? maybe Myth Busters will make a show on this subject. I have heard of vac bagging in the fiberglass boat industry.
