7. Move the carriage stylus to the left hand
limit of the profiled area and adjust the left
hand stop until it is in contact with the car-
riage. See figure 14. Tighten the stop with
a Phillips head screwdriver.

8. Repeat the procedure for the right hand
stop.

9. Once the template and the workpiece are
both securely in place, loosen the cutter in
its collar and adjust it until both the cutter
and the stylus are just touching the work-
piece evenly and the template evenly. It
is essential for accurate copying that the
cutter tip and the tip of the stylus always
remain at the same positions in relation to
the workpiece and the master profile. Slide
the carriage away from the workpiece, so
both the stylus and cutter are well away
from your work.
10. Ensure that everything is secure and turn
on the lathe at its slowest speed. Slowly
advance the cutting tool toward the left
edge of the workpiece. Once contact is
made, advance the cutting tool into the
copy spindle approximately
longitudinal handwheel so the carriage
travels from stop to stop.
11. After each pass, extend the cutter another
/ " (maximum) and repeat with another
1
16
pass. Repeat this process until the stylus
comes in contact with the template.
12. Watch the tool carefully as you make each
-16-
/ ". Turn the
1
16
pass. If it tends to bite or gouge the work-
piece, back the cutter slightly and try again.
Be conservative when removing stock.
13. After you've made several passes with the
cutting tool, turn the lathe off and inspect
the results. It should not be tapered. If it is,
the Copy Attachment is not properly aligned
to the axis of the wood lathe. Re-align the
attachment, according to the instructions in
the Assembly and Adjustment Sections and
re-try with a new test cut.
14. If you are satisfied, continue to remove
material from the workpiece, using the
"downhill" cutting method shown earlier.
Remember, trying to cut "uphill" will likely
result in chipping and gouging. Don't do it.
15. Continue removing stock until the work-
piece is complete. See figure 15.

16. After completing the initial copy, continue
following these procedures until all the
spindles are completed.
17. When all spindles are complete, remove
the Copy Attachment and replace it with
the lathe's tool post.
18. Use appropriate lathe chisels to sharpen
details and smooth the turned surfaces of
each copy. Sand smooth.
