Step 7: Set it up and see if it sucks...

Um... What about the "pump" part? You showed several brass attachments and you mention a garden hose, but there's no pump here anywhere or am I missing something? Because a vacuum chamber without a pump is just a pretty tube.

I usually us a shop vac, milk crate, and garbage bag to degas my silicone, but yours looks pretty good.

Yay! It sucks! Just kidding! (or *am* I?)

Great instructable. I happen to have a lovely glass bell jar without the vacuum base. I need a vacuum source about once a year for one of my projects and now I am inspired to build a base and make it whole once more.
