Need for vacuum guage? ()

>IMO it is silly to use a vacuum chuck without a guage. How do you know what the vacuum is inside the chamber? You should have a valve that permits you to bleed a little air into the vac chuck so you don't pull maximum vacuum on large thin pieces - it will break it.

You can find guages for $10 or less.

You should also have some kind of a filter on the inlet to keep small garbage from getting sucked into the pump and possible ruining the vanes or other guts.
