–Took Grace shopping at Smart & Final.
–Bought a fidget spinner or two.
–Picked up the Wiha needle nose pliers at UPS. Small, but beautiful. Also picked up the NOS Tekna regulator. Can’t test it, as the tank is out for several days being hydro’d. Looks good, needle seat looks great, but the main(?) diaphragm is toast. It should pull the needle back when inhalation stops, but it has lost all its elasticity and just sits there. Fortunately I have spares. Noticed something I haven’t noticed before: inhaling hard on the (not hooked up) regulator allows a little air in. It can be stopped completely with a thumb over the input opening. Tried this on 4-5 regs; some were tight, some not. Is this free-flowing? Is tank pressure going in the same as lung vacuum? I’m just not smart enough to figure out where the “leak” could be. Will definitely do more testing when the air tank comes back.
