TAPER ATTACHMENT

INSTRUCTIONS

For questions or help with this product contact Tech Support at [phone] or [e-mail]

Introduction

This taper attachment provides precision outside
and inside tapers up to 12" without having to off­set the tailstock.

Another feature is the ability to use the attach­ment without disengaging the cross slide. This
allows the taper attachment to be functional at any
time by simply tightening the bed clamp bracket.
However, the taper attachment does not interfere
with other turning operations.

This taper attachment features scales at both
ends, reading inches-of-taper per foot and angle
of taper. An adjustment knob with fine threads
achieves precise control when setting tapers.

taper attachment leadscrew and handwheel
can remain installed by re-installing the
bracket and the components in the same
order. The bracket is mounted to the saddle
in the same manner as the taper attachment
