Slight delay after "learning" how to use my little new lathe... was learning to thread and lets just say it didn't go so well... So after learning to turn down the spindle speed when threading, I ordered a new drive belt :facepalm: and they just came in yesterday, so back on the lathe, i finished turning the fitting. If I had bigger bar stock, I coulda make it so there were no adapters, but I was forced to use 1/8" NPT fittings for the gauge and airline, so I had do use an adapter to the air line fitting...
This is entirely unnecessary as you can use the fill bottle fitting or drill out a 3/8-16 bolt and make it work, but hey, smoke 'em if ya got 'em lol.
So to summarize the part, its a 3/8-16 thread with o-ring on one end, a 1/8" npt pressure gauge in the middle, and a air quick-connect on the other end, drilled the whole way thru. Hopefully it works!
Heres the finished product, hope to drain the drive and pressure test tonight. I also noticed the gauge is floating above 0 so hopefully when i test the fitting it will drop back down (thats what i get for a cheap harbor freight pressure gauge lol)...
