I'd like to work with some bike-tire parts while at moderate pressure (60 psi), so I'm hoping to use a pressure vessel, but it has to be transparent and have inserts so I can use my hands to manipulate the inside. Something like this: Aerosol Containment Chamber however that's a medical chamber, so it can't handle higher pressure.

Are there pressure vessels with hand inserts, or is there a technical problem preventing them from existing?

  • $\begingroup$ The reason I can't work with the parts under standard (1 atm) pressure are that some of them are far too large. I need the 60 psi environment to keep them at a manageable size. $\endgroup$

  • $\begingroup$ So what you want is a hyperbaric chamber with reinforced gloves allowing you to work inside. How detailed is the work you are planning? Threading needles is unlikely - how would you pick up the thread or needle? fitting a 20mm nut to a bolt is more achievable. $\endgroup$

  • $\begingroup$ This might be feasible to a very limited extent, but only if higher pressure is outside. When you have greater pressure inside, it will blow any flexible gloves out of the compartment. With 60 psi pressure difference and 20 cm hole diameter, the glove will push out of the box with approximately 130 N of force. There might be some kind of multistage solution for this, limiting the unbalance section area to your forearm section after you insert the hand (at this point you might want to have an off switch which you can operate with both hands in the box ;)). $\endgroup$ Dec 3, 2023 at 10:39
  • $\begingroup$ Redesign the higher pressure chamber with higher thickness (adding steel frames along edges if needed ), after calculating the plate bending stresses. $\endgroup$

  • $\begingroup$ how would you keep circulation in your hands going with 60 psi acting on your hands? ... the pressure may even force air that is trapped inside the gloves into your bloodstream $\endgroup$
