Well, I bit the bullet and bought a Pressure pot so I can do pressure/vacuum casting.
For the vacuum chamber, I welded up some .25 CRS plate into a four sectioned vacuum chamber that has a 1" thick acrylic top. Each chamber can contain separate loads of dye, stabilizer, resin, etc and be shut off if not loaded.
The Pressure tank came from EFD and is rated for 100 PSI (see picture.)
My question is: How to configure the connections on the pressure pot.
There is the orange pressure relief valve, no issue there.
I installed the vacuum line with a check valve that will run off my vacuum pump used for my veneer press. That way I can also run vacuum to the pressure pot as well as my vacuum chamber.
Then there is the pressure gauge that has a fitting on the top and a black plastic, threaded "something-or-other" screwed into the top. What is it? The plastic doohickey is closed off at the bottom, so there is no pass-thru...
Where do I connect the incoming line from my compressor? Should I connect a T fitting to the center fitting and add flow control (or two) that I can switch between outgoing (vacuum cycle) and incoming (pressure cycle)?
Should I remove the black plastic mystery piece or leave it be... Hummm... Any suggestions would be much appreciated!
Thanks!
