How do you lubricate the spindle bearings in an Index Model 40 Mill? I am slowly working on getting my Index 40 mill in good running condition. It actually runs pretty well, but I am going over it and cleaning and checking everything. Regarding the spindle, there are two holes in the right side of the quill. Each is plugged with a slotted plug screw. The upper one is accessible only through a hole in the quill housing. I removed these plug screws from their holes. The lower one exposes the spindle. The upper hole bottoms out in a conical hole into something brass. Are these lubrication points? It does not seem so to me. I tried squirting a small amount of spindle oil in the lower hole and it eventually came out between the spindle nose and quill. Oil placed in the upper hole flows back out.
