So we have been having a pretty spirited debate this week in our shop about how a vacuum bag actually works. By spirited I mean people getting dang close to throwing down at work. I was wondering if anyone has an online resource I can use to show that its not actually the bag pulling down but the atmosphere outside the bag that does all the work. I have looked a bit but cant find anything that shows it clearly.
The misunderstanding over how the vacuum bag works has led some guys into thinking that there should be a gap around the perimeter of whatever is in the bag so that the bag stretches and therefore clamps down harder. It has led to quite a bit of rework on projects which has eaten up all the profit we would have made.
Any help would be really appreciated!
