ADJUSTING DEPTH OF CUT
A
The depth of cut is controlled by the ratchet plate A, combined with the micro adjustment knob B. Each notch on
the ratchet plate represents a 3 mm (approx 1/8") depth of cut increment.
When the ratchet plate is locked at the lowest notch, the stylus should just touch the template or sample turning at
its smallest point. Start the lathe up and move the carriage from the left to the right over the entire length of the work-
piece. Keep advancing the ratchet plate one notch at a time until the workpiece is round. Once the workpiece is
round you will start to cut the contours as the stylus contacts them on you sample piece.
When the workpiece approaches the sample turning diameter, use the micro-adjustment depth control knob B to
accurately control the final cutting diameter.
MAKE SURE THE RATCHET PLATE IS SECURELY LOCKED IN PLACE. A LOOSE OR DISLOGDED RATCHET PLATE MAY
CAUSE SERIOUS INJURY TO THE USER AND/OR DAMAGE TO THE LATHE, DUPLICATOR OR THE WORKPIECE.
MAKE SURE ALL NUTS ARE FASTENED SECURELY BEFORE YOU START TURNING OPERATIONS.
DUPLICATING FROM A TEMPLATE
This process is the same as duplicating from a turning except you will be using a template instead of a sample turning.
Before you begin, mark a centerline on your template, A. This centerline represents the center points on the screws
of the template mounting brackets, the one that hold a sample turning. This centerline assures that the template is
parallel to the lathe bed. If it is not, your workpiece will be tapered.
1. Mount the template onto the 2 template mounting brackets using the (4) 6 mm hex head bolts and wash-
ers, B.
2. Line up the centerline on the template with the center of the template mounting bracket screws. Tighten the bolts
with the supplied 10 mm open end wrench
3. Position the template backup support at the location that provides the most effective support along the entire
length of the template being used, C.
3. Loosen the locking nut, D, and turn the adjustment screw, E, so that it just makes contact with the template. Tighten
the locking nut back up with a 14 mm open end wrench. This will keep the template from deflecting when the
stylus puts pressure against the template.
Note: The backup support must always be used regardless of whether a template or a sample turning is being used for
duplicating.

TIP: When turning a workpiece of varying diameters, al-
ways try to cut downhill instead of uphill, the bit will cut
better and have less tearout on the workpiece. See
example below.
