Shop Vac or Vacuum Pump for vacuum forming machine?
Hello mates! I'm ready to start to build my own Vacuum forming machine and I have a question about the strength necessary to pull 2.5-3.0 mm HIPS thinness for chest plate and helmet Stormtrooper a like armor.
Which one offer the best pull? Or which one will last more and endure, considering medium usage. I don’t to expend money in something that doesn’t works good for my proposes.
I’ve considering a 2.5 HP shop vac and a 5 or 6 CFM Vacuum pump. Is enough? The size of pull is 80x60 cm.
