Another general work-aid, I built this manifold so I could run all my vacuum-pump dependant devices without having to swap hoses.
It looks pretty nice considering it's kinda a throw-together. The gauge isn't even slightly calibrated, but I have precise gauges where I need them; here it just serves as a general indicator.
A bunch of miniature ball-valves hold back air pressure just fine. They just screw into holes I drilled and tapped in a block of aluminium I had sitting around. The whole lot got mounted up on a perfectly shaped piece of steel I also had sitting around (it's actually the base of an angle-poise lamp!).
Far left is the UTA valve (up to air) for letting the system up to air pressure when not in use or when a separate vac-release is not fitted further down the system.
Next is the black hose that goes to my dental vacuum furnace, which I aim to use for enamel & heat-treating in future once I've repaired the temperature readout.
Next runs to the small vacuum-degassing chamber and is usually left open since the chamber has it's own valves.
Next runs to a quick-connect fitting for connecting the vacuum-forming tables. This is unlikely to be leak-proof but the formers don't need perfect vacuum.
The next one is reserved for a future very-large degassing chamber.
The final one leads to the catch-pot of the vacuum pump, which catches any spilt fluid or particles that might otherwise be ingested by the pump.
