introduction
inventory
the Model h8071 drill press lathe attachment
allows wooden workpieces to be turned on a drill
press in the same manner as a wood lathe. items
like small pickets, legs, spindles, handles, dowels,
and pins can be made. Fits drill press tables with
t-nut slots or with slotted through holes as shown
in figure 1.
refer to the list and figure 2 to inventory your
package. if you can't find an item on this list, check
the mounting locations or examine the packaging
materials carefully. occasionally we pre-install
certain components for shipping purposes.
if any nonproprietary parts are missing (e.g. a
nut or a washer), we will gladly replace them; or
for the sake of expediency, replacements can be
obtained at your local hardware store.

operation safety
read and follow these safety precautions:
respiratory protection. always wear a
respirator when using this tool. Wood dust may
cause allergies or long-term respiratory health
problems.
damage to your eyes, lungs, and ears could
result from using this machine without
proper protective gear. always wear safety
glasses, a respirator, and hearing protection
when operating this machine.
avoiding entanglement. Keep long hair and
loose clothing such as sleeves, belts, and jewelry
items away from the workpiece and chuck.
WorKpiece condition. always inspect the
condition of your workpiece. NEVEr turn stock
with knots, splits, and other potentially dangerous
conditions. all glued joints must have high quality
bonds that will not fly apart during operation.
mounting WorKpiece. Before starting, be
certain the drive and spur centers have been
properly imbedded into the workpiece, and that
the table is locked in place.
loose hair and cloth-
ing could get caught in
machinery and cause seri-
ous personal injury. Keep
loose clothing and long
hair away from moving
machinery.
using tool rest. NEVEr attempt free-hand
turning, you must always support the chisel on the

tool rest, and keep the tool rest gap to ⁄8" to ⁄2
when ever possible.

turning speed. select the correct tuning
speed for your work before starting the drill
press.
no list of safety guidelines can be complete.
every shop environment is different. always
consider safety first, as it applies to your
individual working conditions. use this and
other machinery with caution and respect.
failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
using sharp chisels. Keep chisels sharp.
dull chisels require more force to cut, causing tool
chatter and grabbing hazards.
material removal. attempting to remove too
much wood at once may cause the workpiece or
chisel to eject causing severe injury.
Sandpaper
NOTICE
Wrapping the sandpa-
per completely around
the workpiece will pull
your hands into the mov-
ing workpiece and may
cause injury. never wrap
sandpaper completely
if you have never used this type of machine
or equipment before, We strongly rec-
ommend that you read books, trade maga-
zines, or get formal training before begin-
ning any projects. regardless of the con-
tent in this section, grizzly industrial will
not be held liable for accidents caused by
lack of training.

operations
Follow all safety precautions in your drill press
owner's Manual and these instructions.
feeding the tip of the chisel into the work-
piece at to 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 perpen-
dicular to the workpiece so it drags across
the workpiece rather than digging in.
to use the drill press lathe attachment:
1. put on safety glasses, a face shield, and tie
back loose clothing and hair.
2. disCoNNECt drill prEss FroM
10. tightly hold the chisel, and position your
hand and the chisel against the tool rest as
shown in figure 6.

—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.
11. hold the chisel tightly so it is perpendicular to
the workpiece, and slowly feed the chisel into
the workpiece.
5. place the workpiece pilot hole onto the live
center tip, and hold the workpiece in place.
12. 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, readjust the tool rest as
required to keep the gap at a safe minimum.
6. 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.
7. Clamp the drive center shank with the chuck,
lock the table into position and make sure all
fasteners are tight.
8. Verify that the drill press is set to the correct
speed for the turning operation. the typical
spindle speeds for turning are listed below:
Unsafe
Area
—For roughing, start with a spindle speed of
750 rpM.
—For shaping, start with a spindle speed of
Rotation
Safest
1500 rpM.
Direction
Area
—For finishing, start with a spindle speed of
3000 rpM.
9. turn the workpiece by hand to ensure rota-
tion is unobstructed, and start the drill press.
