A parts list? Lots of brass!
Really though, 5/8" brass tubing and brass strip for the body. Noteworthy for the switch is a section of presta tire valve and 2 valve nuts to give stability to the thin brass. Also the brass carpet tack button is soldered to a lock nut with the nylon removed-- surprisingly strong, and very nice to press.
I'll try to get some internal pics tomorrow.
MisterD, The valve was there the whole time, just not getting the proper attention. It's the center pin in the connector. My insulator came apart, so i replaced with a 510 refillable carto one, which is a bit loose for the center pin but better quality rubber . Adding a tiny o-ring (like Dreams uses for hose fittings in her nico-drips) around the center pin makes for a nice springy seal. Much more responsive in controlling the airflow.
And Xanax, it vapes like a charm, fuller and richer than my 5v regulated. 2 batts get me through the day
