I create small Smooth On resin items and really need a vacuum chamber!! I am getting sick and tired of throwing out pieces because of freakin' air bubbles!
I see name brand vacuum chambers that run in the $500 to $1000 range. I came across Nalgene polycarbonate vacuum chambers that start at $150 sans pump. Has anyone tried using these for small castings? What pressure do you require for removing bubbles from resin or from silicone molds? Would this Nalgene system suffice?
Thanks in advance!!
