Hadn't posted here in a LONG while. I think !?! :^D
I really DID just stumble upon some of the works of the ABANDONED Hydraulic Tracer apparatus that was the factory supplied HIGHEST END model in 1953 when my AMERICAN PACEMAKER was built. It was NOT an attachment per se , as most of these units were. I ran MANY different (ADD-ON) units from 1978 to about 1982?
I will share some pics in a bit. But I will tell you for certainty that the operation pressures were from 120 psi on the rather small units , to the more common 300 psi units on the 16"-20" Lathes. Some had a cylinder stroke around 14". Mind you ALL of the operated at AN ANGLE relative to the Chuck. Usually 30° degrees but I seem to recall some very small ones that used 45° .
They all operated on 10 weight hydraulic oil , ISO 32 certainly will work.
My old lathe still had the lubricants listed in - " SAYBOLT SECONDS ".
