One of my early experiments with the vac chuck the first time I hade a

and pulled the center right out of the bowl... I had the tailstock
snugged against it, so it just played hula hoop until I shut the lathe
off...

When I first got mine I calculated that on a large bowl it would put a
total of 500 pounds of pressure on the outside of the bowl without the
vac bleed. Like driving over it with a small car. It is not that
efficient now.
