[QUOTE="Meller9.3, post: 441823, member: 13297"] Holy thread revival batman.... but i was obliged to comment because for once i actually know what i am looking at! Manpa and mbasko are onto it. It is one half of a Phosphor bronze bushing, this one in particular was half of a headstock spindle bushing from a myford ml7 metal lathe. This was the top bushing of the chuck end, adjacent to the back gears. An oil dripper fed oil to the spindle for lubrication and the tension on the spindle was adjusted using fore and aft shims. Too little tension caused runout and chatter, too tight ate the bushes. Id consider that a pretty darn cool find! A pic of my myford ml7 [img]https://www.prospectingaustralia.com/forum/img/member-images/13297/1537971148_13d7d8c0-715f-40ca-9775-0d2c9caf4bd4.jpg[/img] [/QUOTE]
