Not sure if this is the right forum, but does anyone have a good lead of where to source the typical ball type (check valve maybe?) oil nipples like often found on lathes & mills? Actually let me rephrase - BETTER quality that what is typically found... After dismantling my lathe its now obvious some of the nipples may not have been accepting oil very well. I just assumed they were meeting flow resistance in between close surfaces where lubrication was require. I saw on Stefan's YouTube channel Vertex rotary table Teardown he replaces with some nice ones. Red dot = new, silver = original like mine. The other related issue might be my oiler. When I gave it my typical squeeze using my bottle, it was an anemic little squirt in the passage now that I can witness the true volume with no obstruction. Is that what these oversized hypodermic needle looking units are all about? Saw on ebay but looked like UK source & didn't ship to Canada.
