A threaded hole is not likely to be for a dauber.

I suspect the hole was threaded at a later time for the plug. :)

It has a plug in it now.
A grease fitting is what I usually replace those dauber things with. I never knew what they were called, but have run across quite a few of them in my old boats and machines.
Are you sure you are not referring to grease cups?

The "Dauber" was one little dip thing with a knob atop. They weren't screwed in, more of a taper and more of them lost. It was in the tail stock as said before. There was only one place to use the white lead/greasefat around the lathe and that was to daub the dead centers so they wouldn't burn. Newer lubes take that place for the convenience.

Live centers have provided some convenience, too.

Yes, I was thinking of grease cups. Thanks for the clarification!

Here is a dauber from my SB 9. Tiny little thing. It lives in a hole in the quick change gear box. In addition to lubing dead centers with tallow and white lead, I wonder if these also were meant to close up oiling points. My lathe has several of these, maybe 3 or 4, at spots that look like strategically placed locations to apply lube oil into the machine. Although this one could easily be located to lube the dead enter in the headstock- it's right nearby.

I have a 1937 B&S surface grinder that has similar plugs all over it.

They are to plug the oiling holes to keep dust and debris out.

Wait a minute here. The "dauber" is one single daub of a lube for dead centers. That is all I know. Similar plugs in different areas are for sealing the lubrication ports as mentioned above. The "dauber" has a tube or rod to drip lube and within inches goes back to the tailstock pocket of that lube.
This is a non issue.
