I got a vacuum to screw around with(and eventually make a balsa/EPS/epoxy board later on), but the problem is that it only goes to about 20 mm Hg on the regulator which doesn’t feel like much suction when I put my finger over it. For all you guys that do vacuum bagging how much do your vaccuums pull?
I turned a blank and bottom skin into a bannana, increased nose and tail rocker by like 4-5" each and decreased thickness by 1/4", by forgetting to dial back the pressure control after emptying a bag. Sucked it (1lb eps) at like 24"hg. Now I do it all at 10-13, no problems.

There are many ways to describe vacuum level. But you are saying “mm” Hg. 20 Torr is a fairly high level of vacuum. Everyone else that has posted to this thread seems to be talking about Inches Hg.
