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

Re: Thread cutting with no Qc gear box
I suspect the hole was threaded at a later time for the plug.

Are you sure you are not referring to grease cups?liveaboard wrote:Now I know what that threaded hole in my tailstock was made for.
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.

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.
Re: Thread cutting with no Qc gear box
Live centers have provided some convenience, too.

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

Re: Thread cutting with no Qc gear box
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.

Re: Thread cutting with no Qc gear box
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.

Re: Thread cutting with no Qc gear box
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.
