A machinist uses a Dial Indicator to manually check the alignment of the tool tip to the spindle.

Here are the steps:

1. The machinist first secures the dial indicator to a stable surface. This could be the machine bed, a magnetic base, or any other surface that won't move during the measurement process.

2. The machinist then positions the dial indicator so that the plunger (the part that moves in and out) is in contact with the tool tip.

3. The machinist rotates the spindle by hand, watching the dial indicator's needle. If the tool tip is perfectly aligned with the spindle, the needle won't move. If the needle does move, it indicates that the tool tip is not perfectly aligned with the spindle.

4. The machinist adjusts the tool tip's position until the dial indicator shows that it's perfectly aligned with the spindle.
