[NSRCA-discussion] Vacuum Bagging

That should have been 3psi, not 5 ( one fifth of atmospheric ).

I have enjoyed wing building since I received the vac system. It's like magic and does not require a strong table, just a flat spot. If you use Midwest ( precision ) balsa you can eliminate sanding going into the bag and tape the sheets together, very fast into the bag. I have gone to 1/32 sheet, actually .040, which is an optional cut from Midwest.

I think the only way you can specify density with Midwest is with a $200 minimum per item. Your time makes it worth it. Very little sanding out of the bag.

  I vote with Verne. Buy the cheapie system ACP sells if you plan to use .7 to 1.5# foam. It pulls the right vac ( about 6 in. hg. or 5 psi ) without a pressure regulator. It is very convenient to use.         

  If you have questions holler.              Nat

    I am thinking of buying a vacuum bagging system. What is the recommend vacuum for sheeting a foam core wing? Any tips or info sources?
