D4088 Lathe Attachment Instructions
Operations
Follow all safety precautions in your drill press
Owner's Manual and these instructions.
To use the drill press lathe attachment, do these
steps:
1. Put on safety glasses, a face shield, and tie
back loose clothing and hair.
2. DISCONNECT DRILL PRESS FROM POWER!
3. Install the required driving center into the
upper end of the workpiece:
— If the workpiece diameter is 3 ⁄
4
" or less,
thread in the screw center.
— If the workpiece diameter is 3 ⁄
4
"–3", tap in
the spur center.
— If the workpiece diameter is 3" –6", tap in a
2" diameter forstner bit as the drive center.
You may have to slightly enlarge the pilot
hole to accept the forstner bit pilot.
4. Place the workpiece pilot hole onto the live
center tip, and hold the workpiece in place.
5. Without losing spindle alignment, crank the
table up so the drive center shank enters the
chuck and the live center seats in the pilot
hole.
6. Clamp the drive center shank with the chuck,
lock the table into position and make sure all
fasteners are tight.
7. Verify that the drill press is set to the correct
speed for the turning operation. The typical
spindle speeds for turning are listed below:
— For roughing, start with a spindle speed of
750 RPM.
— For shaping, start with a spindle speed of
1500 RPM.
— For finishing, start with a spindle speed of
3000 RPM.
8. Turn the workpiece by hand to ensure rotation
is unobstructed, and start the drill press.
Feeding the tip of the chisel into the
workpiece at too sharp of an angle will
cause the chisel to dig into the workpiece,
which may eject the chisel or workpiece and
cause severe injury. Always keep the chisel
perpendicular to the workpiece so it drags
across the workpiece rather than digging in.
9. Tightly hold the chisel, and position the
chisel against the tool rest (see Figure 6).

10. Hold the chisel tightly so it is perpendicular
to the workpiece, and slowly feed it into
the workpiece.
11. Keeping the chisel within the safest
working area shown in Figure 7, carefully
slide the chisel up and down along the tool
rest to shape the wood. Keep in mind that
the closer the chisel moves toward the end
of the tool rest the easier it is to slide the
chisel off of the end. Working closer to
the end of the rest can also increase tool
chatter. As workpiece diameter decreases,
re-adjust the tool rest as required to keep
the gap at a safe minimum.
