Drill Press Speeds

The speed of the drill press spindle is controlled
by 2 groups of belts and pulleys. The belt posi-
tions on the end of the lathe control one speed
range. See Figure 23. The belts and pulleys
above the drill press control the other range. See
Figure 24.
Figure 23. Lower pulleys for speed changes.

Figure 25. Speed chart.
Unplug the Lathe/Mill! Before using the drill
press, the hub at the end of the lathe spindle
must be adjusted to the "in" position. See Figure
25. To ease engagement of this hub, slowly
rotate the drill spindle by hand while applying
pressure to the hub.
The chart also shows the various combinations of
belt positions for achieving a desired speed.
Example:
To select a spindle speed of 310 R.P.M., start by
moving the belts at the end of the lathe. Move the
lower belt to the "B" position. Move the upper belt
to the "F" position. Follow the belt changing pro-
cedures in the section titled Lathe Speeds.
Next, move the belt located above the drill press
to the "L-H" position.
