I found this specification performance of a lab aspirator used as a
vacuum-pump

Air removal is extremely rapid. Evacuates liter of air to 28 inches of
vacuum in 30 seconds with water pressure of 60 pounds. Also works with
compressed air sources to 60 psi."

If push comes to shove, you could use an idling automobile engine's
vacuum.

That is a great idea. All you have to do is make sure no resin get in it.

Paul, Paab makes air power ejector vacuum pumps which are great for composite work. You can get single stage versions
for about $5. Almost throw away price. Need and air compressor.

I think you mean Piab.

That works off an air compressor if you have one.

You put in 25 to 97 psi and it generates a vortex. The core of
the core of the vortex is less than atmospherics pressure. The last time
I used one it did not work well but some advancements may have been made.

Also a venturi principle works.

I fixed a small seep in my gas tank recently with a 12 volt vacuum pump from a food heat sealer, some pro-seal, and the
head from a toilet plunger. AS&S has a few air pumps that might also have a port to be used as a vacuum pump.

Brian,

How's it going? Are you ready to fly again?
