So true! too many folks think those spring ball bearing oil ports are for grease, I have seen several machines where a grease zert was installed believing this would be an upgrade.Glad to know it (your post) was a victim of a missed auto-correct, rather than an accurate reflection of reality.
I am really impressed by your work!
Have read too many reports of fellas dealing with grease filled machine tools, when the maker installed the same style of nipples but expected the users to read and understand that an Oil Gun, rather than a grease gun, was the correct tool to be applied.
