    Acrylic Vacuum Chamber w/pictures

    Well, It looks like something from a Mad Scientist lab but it works. I got the pump and all the acrylic at a surplus store. I think I've got $20 rapped up in the whole thing.



    I also got a cradle so I can mount it on it's side. There are pieces of acrylic in the bottom for a platform. Hard to see, too much clear stuff.


    Here's boiling cold water.



    And a shot of some of the other acrylic pieces I got. I don't know what I'll use them for, I just had to have them.


    Hopefully, I'll de-gas some RTV Silicone this week and make some molds.

    Looking good Jammer , when you de-gas your RTV make sure the container is large enough that it doesn't boil over the top.
    Also change the oil regular especially if de-gassing investment cement as the water will turn the oil cruddy , I use synthetic motor oil seems to work OK and is much cheaper than vacuum oil.

    Thanks Abby.
    We changed our vacuum pump on the spectrometer at work. Of couse the new one takes "special" oil so I scored 2 Gal of Welch oil for mine. It only takes about a pint to fill it so it should last me a while.

    Very professional looking, Jammer! I remember that experiment from high school chem, the teacher got it to boil and freeze at the same time. Look forward to some results!

    It looks awesome, we used to use one for testing our molten aluminum after degassing on certain parts we made.

    Very nice job.

    BTW, I was looking at some clear cake keepers at Wallyworld the other day and was wondering if anyone has ever used one of those as a vac chamber?

    I don't know, it would be pretty thin. I doubt it could take the pressure. I was surprised this thing worked and it's a 1/4" thick.
