Vacuum cleaner for bagging use
I'm sure it's been done, right? The idea is to make a PVC vacuum tank and use a ball valve (or something else that's better?) to seal it once the vacuum cleaner has done its thing. Does it work? Or is leakage too big an issue?

I thought about those after making my reply. If I am correct I think the bag material is pretty thick? May still work for bagging wings though provided it will hold vacuum at a constant rate.

That's what got me thinking about it. Yes, the plastic is pretty substantial. They hold vacuum for a year or longer. I don't know if it's enough vacuum though.

Or if it's too much. I bag wings cut with 1lb density foam at 5" vacuum. I think at around 10" the foam will crush. I had a vacuum switch failure once and discovered a 1/4" thick wing in the morning. For the cost of a set of cores and sheeting you can build a vacuum system.

Yea. they crush my shirts but the do hold for a long time. I guess just using the eyeball method for watching vacuum pull could be a problem using a vacuum cleaner anythime.

Speed, do you have a link to plans for a vacuum system? I' know about the EZ vac. If I build more, it would make sense. But I'm a one plane a year guy at best.

Jester, all you need to do is buy the vacuum switch on the link that Invert provided, find just about any vacuum pump at a surplus store. Make a tank out of 3" PVC pipe and caps. Install the vacuum switch to the tank and wire the switch to the pump. Plumb a line from the pump to the tank with an automotive check valve. Total cost shouldn't exceed $75.

Pardon my stupidity, but there are a lot of vacuum pumps to choose from, and most are considerably more expensive than you're talking about. What kind of surplus store do you mean? I assume I'd be looking for a diaphram or piston type pump? For this application, CFM probably isn't a big concern?
