The completion of what my father told me had been a vacuum chamber. Unfortunately, my father didn't say anything while he was recording. There isn't a whole lot to see in this video, so I've sped it up to 4x. At 7:16, the video returns to normal speed for the testing of the hydraulics that actuate the head of the chamber, and there is some narration at this point (though not by my father).
This work was done at the Pitt-Des Moines shop on Neville Island.

![Extracting a Broken [garbage] Pipe Nipple](https://i.ytimg.com/vi/8GidubxIixM/mqdefault.jpg "Extracting a Broken [garbage] Pipe Nipple
The process used to extract not only a pipe nipple, but a pipe nipple made of a sintered material, presumable brass or bronze.
The process involved cutting away as much as possible of the damaged nipple using a bolt extractor, since a purpose - made nipple extractor would not fit in the garbage nipple.
The bolt extractor bit into the material of the fitting, however, instead of extracting it, it pulverized the material. I continued this process until I began to bite into the threads of the tank bung with the extractor.
At this point, I began using a 1/4 NPT tap to cut the remaining material out of the original threads. After clearing all of the material, I made a final pass with the tap in order to ensure a clean mating surface for the new STEEL pipe nipple.
