G2891 Lathe Copy Attachment -13-
Cutting Tool
The cutting tool can be positioned closer or far-
ther away from the workpiece by loosening the
setscrew at the top of the cutting tool collar. Use
an 8mm Allen
®
wrench to make collar adjust-
ments. To install or replace the cutting tool:
1. Loosen the setscrew on the cutting tool col-
lar.
2. Insert the cutting tool with the triangular
cutting edge up. See Figure 10.
3. Tighten the setscrew.

Copy Stylus
To ensure the greatest level of precision while
copying from a template or a master profile, it is
essential that the Copy Stylus is properly posi-
tioned at the underside of the travelling carriage.
When adjusting the stylus, keep in mind that its
follower edge should be centered on the template
or master profile, so the narrowest point fits
securely within the profile. To adjust the stylus:
1. Center your master profile on the copy cen-
ters, or attach your profile template to the
attachment brackets included on the front
of the Copy Attachment body. Insert the
stylus so the rounded edge of the follower
contacts the master. See Figure 11.
2. Be sure that your template or master profile
is perfectly parallel to the Copy Attachment
bed by repeating the procedures used to
check alignment between the lathe centers
and the Copy Attachment. This time, move
the stylus from one end of the template or
master profile to the other by turning the
longitudinal handwheel. The cross-slide
handwheel will allow you to adjust the loca-
tion of the stylus, so you can find points on
either end of the profile which will allow you
to ensure proper alignment. Adjust the sty-
lus height until the follower edge is cen-
tered on the template or profile. Tighten the
setscrew to secure the stylus.
