Oops, a vacuum chamber off ebay collapses once a fresh gasket is poured
A piece of the back wall of the chamber where the vacuum attachment was made. The compressor end of the hose, the rest of the back, and some other pieces too. The little joe yard tug molds were damaged, the acrylic backing and the
         other sides, reservoir tore.

The door and side wall, the oomoo 30 replacement gasket, and
         splatters of color match resin in it with red dye. A sharp piece of wall/side punctured a water bottle.

    What appears to have happened was a combination of two things:  The original chamber had three metal shelves, which I removed to allow the molds to stand up.  Also the chamber's gasket was old so I poured a new one allowing the chamber to reach a deeper vacuum.  Age and weakness in the chamber's old joints and the removal of the metal support shelves allowed it to just go phooop!  I was not wearing safety goggles, I now do.  Luckily I was totally unharmed!
