2. Remove the taper att ac hm ent f r om the box .
3. Remove the dust cover (29) held in place
with six screws (5).
4. Loosen and remove gib screws (16 & 24) .
Do not adjust or rem ov e gib screw (24A);
this will aid assembly when putting the taper
attachment together.
5. Remove the longitudinal slide assembly (6 &
11) from the slide base.
6. Thoroughly cl ean all par ts of the taper
attachment wi th cleaning solvent.
7. Remove two nuts (A, Figur e 1) and the
bearing cap (B, Fi gur e 1) fr om the end of the
cross slide screw (C, Figure 1)
8. Remove the thrust bear ing assembly from
the cross feed screw.
9. Remove two hex socket c ap screws (D,
Figure 1) and the block (E, Figur e 1) .
10. Attach the main body (A, Figure 2) to the
carriage wit h two M8 x 30 hex socket cap
screws, and two M8 fl at washers (B, Figure
2). Tighten the hex cap screws to hol d the
main body in place but l oose enough to
allow adjustment with a dead blow hammer,
or rubber mallet.
11. Pl ac e the cr oss sli de block (A, Figure 3)
onto the taper sli de r est ( 22) .
12. Posit ion the main body so that the hole in
the cross slide bloc k (B, Figure 3) lines up
with the cross slide screw (C, Figure 3).
13. Push the cros s slide block to engage the
cross slide screw through the hole in the
slide. It is important to get the slide to pass
over the cross slide screw sm oothly. Use a
rubber mallet , or a dead blow hammer to
position t he m ain body so that the slide
passes smoothly ov er the c r oss sli de screw
without lifting it.

14. Make sure the inner bearing assembly is in
place before r e- assembly, no spacer. The
smaller, i nner diam eter bearing goes on first.
15. Pl ac e the longitudinal slide (A, Figure 4) int o
the main body.
16. Using a di al indicator with a magnetic base
(B, Figure 4) attached to the lathe bed, level
the longitudinal slide to the bed. The slide
assembly is level when it is less than .005”
from end to end. Keep the cross slide block
centered on the lead screw. Use a rubber
mallet, or a dead blow hamm er to position
the main body so that the cross slide block
passes smoothly ov er the lead screw and
that the longitudinal slide is level.
Note: repeat steps 13 & 16 until the longitudinal
slide is level and t he cross slide block passes
smoothly over the cr oss slide scr ew.
17. Tighten two M10 x 30 hex socket cap
screws that hol d the main body in plac e.
18. Re-check the longitudinal slide for level.
19. Clean and lightly oil all gib surfaces that
were previously r em ov ed.
20. Replac e the taper slide, gibs and gib
screws.
21. Check t o m ak e sure the slide moves easily
and without excessive play.
22. Replac e the outer bearing assembly (A,
Figure 5). The smaller inner diam eter
bearing goes on fir st.
23. Install two hex nuts (B, Figure 5). Tighten
the inner nut fir st to snug up the bearing
assembly. Turn the cross slide handle and
check for smooth r otati on. Tighten the jam
nut to hold the adjustment.

Figure 5
Note: It is not necessary, but a good idea to drill
and pin the taper i n plac e through the slide
bracket (3N).
24. Replac e the dust cover.
25. Thread the lock down linkage (A, Figure 6)
into the end of the slide assembly (B, Figure
6).
26. Pl ac e the clam p ( C , Fi gur e 6) onto the lathe
bed and tighten two hex socket cap screws
(D, Figure 6).
27. Line up the hole in clamp with the lock down
linkage (E, Figur e 6) and insert . Tighten the
hex socket cap screw (F, Fi gur e 6).

checking t o see that t he taper sli de is
parallel to t he m ov ement of t he carriage.
Note: You will need to loosen hex socket c ap
screws (12 & 13). This will allow you to turn the
adjusting screw (18).
29. When the taper slide is parallel make sure
the screws (12 & 13) are tight , and mar k the
zero point with a chisel .
