If you have an air compressor, you can make a venturi pump (I think
that is what it is called) like HF sells. It is simply a block of
aluminum with a T intersection angle drilled into it. The air from the
compressor blows through the straight drilled holes which creates a
vacuum on the remaining leg. I use mine for air conditioner work and it
will pull 29 lbs of vacuum.

Or salvage a small AC compressor from an old window unit or water
cooler. You will need the run capacitor. Mount it on some type of base and
insulate everything so it is safe.
