I recently did a small project with the case made of 2 layers of bent
laminated 1/8" ply that I applied quilted maple veneer to the outside
and flat cut maple veneer on the inside. Not having a vacuume set up I
had the idea to try using what are called Space Bags that I bought at
Wallmart for a few dollars. All you need is a good shop vac. The bags
are used to store clothes in. You can buy different sizes of bags. I
had no problem holding a vacuume overnite but care must be taken on
the corners or other sharp edges so you don't punch a hole in the bag.
Tape the edges and corners well! I veneered one side at a time.
Although the veneer was fairly flat, I think it would work for
bubblier type veneers if you placed a stiffner between the bag and
Please note, I did not glue laminate the panels with these bags.
Yeah, reminds me of my thermo prof. "Fill one side with an ideal gas, and
fill the other side with vacuum."
Back OT, do fridge compressors really work with air? You just hook the
"suck" side of the compressor to the bag, and Bob's your uncle? Groovy.

they do work. they can be had for free, but there are a few gotchas.
they are filled with a somewhat foul oil, which if you let escape the
compressor dies soon after. so you have this heavy motor/pump thing
that you can't tip. they pull plenty of vacuum for veneering, but they
do it slowly. on the good side, they are quiet and can be left running
