I need a hefty vacuum cleaner to build a vac forming table.

Do you think that a vacuum cleaner will take the pressure low enough.
IME, vacuum formers tend to use vacuum pumps, and go down to a few cm of
pressure. How big a table do you want? How are you heating the plastic,
which types of plastic are you planning to use, etc?

I wonder how your common-or-garden vacuum cleaner motor would regard
being connected in series with a few others with intercoolers in line,
to increase pressure difference.
