The walls of our vacuum chambers are designed to withstand full vacuum (-14.7 psi) and therefore can withstand a positive pressure of up 14.7psi.
I long for a vacuum chamber with all my heart, and the only reason I havent bought one is that workshop space is also an issue, and they tend to be bigger than I would need. Id never use such flimsy shatterable materials as done here, If you are going put something under so much stress you want it deform plasticly when it fails not shatter (or at least be a composite material so theres something trying to hold the shards in). Depending on the depth of the scratch, these may not be easily reparable. Most acrylic vac chambers are an excellent solution for degassing compounds and epoxies.
