Cheap vacuum chamber


Well-Known Member
Hey guys,
as some silicones need to be vacuum degased, I thought this here would be worth posting:

Making a Cheap Vacuum Pump - YouTube

It is not really a "How to" video, but it says what you need to build yourself a cheap vacuum chamber and shows the outcome.

Note: I did NOT build such a vacuum-chamber myself (yet), so please don't ask me questions I probably can't answer :lol

As said, I just thought it might be worth posting as it seems to be an inexpensive alternative to "real" vacuum chambers, and perhaps it helps the one of the other.

no room inside after you put the pump in(n)thumbsdown

Well, the video says it's a vacuum pump. You could make the chamber bigger or make a second one with hose fitting to apply the vacuum.
What worries me is that the pump wasn't designed to do this. Might not live long.
