If you pull a full vacuum you are pressing down with over 2000 pounds

Hello Everyone.
along the lines of glue up's and clamping I thought I would add a few
tricks to help everyone out when doing large glue up's
When gluing large mutable layers, the glue can make the wood slide and
shift when applying the clamps. I was taught to sprinkle some white
sand on to the ends for the boards. the sand will keep the boards form
shifting while clamping, and can easily be cut off after the glue has
tried. (if need be, I have never had any problems using this technique
i the past, Note a very little sand is needed.)
and when I do small glue ups, I use a dollar store rubber spatula to
spread the glue, Its like frosting a cake, The spatula spreads the
glue nicely, (better than a brush.) And once done, I just let the glue
dry on the spatula, the rubber/soft plastic of the spatula is
something that the glue can not stick to ,and will comes off in
seconds. No fuss or muss. ;-)
for large glue up's I use a paint roller... it spreads the glue fast,
its not exactly a clean job, but when time is waiting, its the best
way to get the boards glued together. (at least in my book!)
NOW here is an idea that I was thinking about last night when working
on a vacuum pump.
this is only a idea, Has anyone here tried this? using a heavy plastic
bag and a vacuum to do your clamping of wood? I know that air our air
pressure would be enough to hold the wood firmly in place while the
glue is drying. It might even force the glue deeper into the wood, for
a better bond ???? The glue would not stick to the plastic,making a
easer clean up. I would think something like this could work for
anyone doing glue up's, it would be quick and easy to do, if you have
the right equipment. And I think it just might be cheaper than buying
600+ clamps? (any takers on this idea?)

Very large jobs move faster with more clamps. If you only have a few
clamps, you spend all your time waiting for the glue to dry. That is
not time effective. By the time the I finish with my last set of
clamps, the first set has had enough time to be removed and used
again. From that point it is just a matter of cycling clamps onto new
boards and taking the cured boards to the next work station. Creates
constant work and is very effective. When you do this for a living,
you don't want to keep the customer waiting.

OK

Why do so many clamps ? A lesser amount.
