Installation
To install taper attachment:
1. DISCONNECT LATHE FROM POWER!
2. With assistance of a helper and using a 5mm
hex wrench, remove the three cap screws
holding the splash guard on the lathe.
3. Use a 5mm hex wrench to remove three
cap screws securing rubber chip cover (see
Figure 3), exposing leadscrew end cap.
5. With one hand ready to catch race and ball
bearing cage, use your other hand to pull
leadscrew end-cap off of leadscrew (see
Figure 5). Leave inner set of bearings on
shaft.
Note: Make sure to keep the correct race
with its original bearing, and do not hammer
on the casting or chisel the races out. The
races are merely a loose fit. If they are dif-
ficult to remove, be patient and spray some
penetrating oil into the bore and carefully
work the race out from the grease suction
that is holding the race. You can also soak
the casting in mineral spirits to break this
suction.

cover.
6. Use a #2 Phillips screwdriver to remove eight
flat head screws and taper attachment top
plate (see Figure 6).
Figure 6. Top plate removal.
4. Use a 6mm hex wrench to remove two lead-
screw end-cap cap screws. Use two 17mm
wrenches to remove two hex nuts on end of
leadscrew. Then remove bearing cap and
three-piece thrust bearing (see Figure 4).

7. Use a 4mm hex wrench to loosen slide block
set screw (see Figure 7).

Figure 9. Slide block end-cap removal.
8. Lift out slide block without losing brass anti-
score plug (see Figure 8).
10. Use a 5mm hex wrench to remove two cap
screws and slide block end cap (see Figure
9).
11. Oil and install bearings and races onto lead-
screw in order shown in Figure 10. Finger-
tighten first 17mm hex nut onto leadscrew
until bearings are slightly preloaded, then
lock in place with second nut. Make sure slide
block end cap has no lash or end play.
9. Apply a dab of multipurpose grease to brass
plug to prevent it from falling out when han-
dling slide block.
Note: This brass plug prevents the set screw
from scoring the main pivot pin when the
taper attachment is being used.

18. Liberally apply drops of oil at locations shown
in Figure 14.
12. Use a 5mm hex wrench to secure slide block
to end cap with two previously removed cap
screws (see Figure 11).
Note: Make sure the top of both slide and
end cap surfaces are flush with one another
after tightening the cap screws (see Figure 11).
17. Use a 4mm hex wrench to snug slide block
set screw so brass plug is slightly preloaded
against pivot pin (see Figure 13).
Tip: To make the following steps easier,
remove the taper attachment body from the
dovetail slide.
13. Make sure brass plug is still inside slide block.
14. With help of assistant, raise and align taper
attachment body, so slide block drops into
slot evenly (see Figure 12).
15. Use
25
⁄64" or 10mm transfer punch to locate
holes to be drilled and tapped for mounting
attachment (see Figure 12). Once holes
have been marked, drill with (Q) drill bit and
tap them M10 x 1.5.

16. Reconnect taper attachment body to slide.
Raise and align taper attachment assembly,
so pivot pin slides into pin bore in slide block.
Use 8mm hex wrench to secure taper attach-
ment to carriage face.

19. Re-install top plate as shown in Figure 15.
20. Position deadman arm and deadman, as
shown in Figure 16, and use a 6mm hex
wrench to secure cap screws.
21. Turn taper angle control knob (see Figure
17) until dovetail slide is parallel with bed.

22. Use a 6mm hex wrench to tighten dovetail
lock cap screws (see Figures 17 and 18).
One screw is located at each end of taper
attachment dovetail.
23. Move carriage so taper attachment stops
completely at rearmost position (see Figure
18).
24. Set up a dial indicator (see Figure 18), so
dial indicator point is against top of dovetailed
way.
25. Move carriage to other end of way. Read dial
indicator and note amount of total misalign-
ment in parallelism between path of carriage
and path of taper attachment.
Readings on dial indicator showing a tilt of
0.050" or less between two extreme posi-
tions of thetaper attachment are acceptable
and have no significant impact on taper
operations.

Step 27.
—If parallelism is 0.050" or less, go to Step
29.
26. Loosen four mounting cap screws and rotate
taper attachment left or right to correct align-
ment (see Figure 19).

27. When alignment is 0.050" or less, retight-
en cap screws, and double check your
parallelism.
28. Using existing 7.5mm diameter holes in taper
attachment housing as drill bit guides (see
Figure 20), drill two 8mm diameter holes
13mm deep into carriage.
29. Position and hammer in directional roll pins
so they will permanently lock taper attach-
ment in current alignment position.
30. Re-install lathe splash guard.

Operation
6. Retighten both dovetail lock cap screws.
7. Begin lathe operations.
When the deadman cap screws (see Figure 21)
are tightened, the deadman clamps against the
bedway and the taper attachment engages. When
the cap screws are loose, the taper attachment
is disengaged and normal lathe operations can
occur.
To use taper attachment:
1. DISCONNECT LATHE FROM POWER.
2. Move carriage, cross slide, and compound
rest so turning bit is at needed location to
begin tapered cut.
3. Use an 8mm hex wrench to tighten both
deadman cap screws so deadman clamps
against lathe bedway (see Figure 21).
4. Use a 6mm hex wrench to loosen both dove-
tail lock cap screws (see Figures 22 & 23).
To disable taper attachment:
1. DISCONNECT LATHE FROM POWER.
2. Use an 8mm hex wrench to loosen both
deadman cap screws so deadman can slide
on way as carriage is moved.
3. Use a 6mm hex wrench to loosen both dove-
tail lock cap screws.
4. Turn taper angle control knob until reaching
"0" on taper scale.
5. Use a 6mm hex wrench to tighten both dove-
tail lock cap screws.

5. Turn taper angle control knob (see Figure
22) until you reaching desired taper angle, as
indicated by taper scale (see Figure 23).

Always disconnect power
to the lathe before per-
forming maintenance.
Failure to do this may
result in serious person-
al injury.
Using an oil can with the same oil you used on
your lathe ball oilers, apply liberal amounts of oil
to the three ball oilers, the pivot pin, and the dove-
tail surface shown in Figure
24.
Lubrication
Vacuum excess metal chips and wipe off the
remaining metal, coolant, and oils with a dry
cloth.
If any coolant sludge has built up, use mineral
spirits to remove, and then relubricate with the
same oil you use on your lathe or use G96
®
Gun
Treatment, SLIPIT
®
, or Boeshield
®
T-9 to prevent
surface rust.
Cleaning
Using an oil can with the same oil you use on your
lathe ball oilers, apply oil on the knob threads and
the dovetail ways shown in Figure
25.
