A large round brass/copper plug of some kind is apparently adjacent to a hole in the ?base? of similar diameter, but I cannot tell how that relates.



Somehow 50 years of casual amateur fabrication on my 9" South Bend thread-turning lathe has not equipped me to figure out how the device works; with all due respect, I suggest that the pictures and description would benefit from having about 50% more detail, perhaps with a diagram of inputs and outputs, for the newcomer to diemaking . . . we all tend to gloss over a few steps and details of mechanisms with which we deal on a daily basis, just need to step back a little and look at our work from a newcomer's perspective to ensure clarity. Certainly the workmanship IS of superior quality, nice work!
