Degassing chamber

I'm finding that I can't get rid of the bubbles in the resin cup prior to doing an infusion and I need a degassing chamber.

I've seen them advertised but if I'm correct you put the resin cup in the chamber and pull a negative pressure same as the resin infusion extraction system.... So could I in theory just use the little resin infusion chamber I have now?

If so I might make a slightly larger chamber and put a link to the pump and pull a pressure to it as same time as the part as required?

If this isn't would can someone exactly explain were my understanding is wrong :-)

I use degasing chamber to extract the microbuble to get a super clear resin only if I involve on realy complicated mould such as lips fender, when the mould is too complicated it will cause a bridging "the CF not perfect stick surface on the mould" the the gap expose the microbubble.
