(Part 3) Best vacuum & pump equipment according to redditors

How about rigging a hobby servo to a stopcock like one of these.

Using Amazon and Medlabsupply for ease (two stop shop). I havent found much better prices (maybe a few cents..) in my homebrew career. My setup is a bit more expensive than whats listed lol.

Something like 2-3 cfm (55-85 l/m) is a good starting point for smaller vacuum chambers, like this one:

...but you're getting a big one, though, so you may want to aim at 6-9 cfm (or get a smaller chamber).

You don't really need a vacuum gauge; a chamber with a transparent lid is a lot more useful, because it lets you diagnose problems and time the process more easily.
