DUPLICATING A TURNING
Move the left pattern holding bracket (A) Fig. 80 to the left edge of the duplicator guide rail, and place the turning (B) against
the threaded center pin (C). Move the right pattern holding bracket against the turning on the right side of the duplicator.
Thread the center pins of the pattern holding brackets (A) Fig. 80 into the ends of the turning (B) to prevent the turning from
moving as the follower arm moves across the contours of the turning. Lock the pattern holding brackets (A) in the desired posi-
tion on the duplicator guide rail. Slide the safety brackets (D) against both ends of the turning (B) Fig. 80, and tighten lock screws
(E). IMPORTANT: These safety brackets (D) will prevent the follower arm from accidentally moving off the turning and
damaging the tool bit or causing personal injury.
Slide the two support brackets (F) Fig. 81 to the areas adjacent to the turning (B) where support is needed to prevent deflec-
tion as the follower arm (G) moves across the turning (B). Loosen two locknuts (H) and move the two support screws (J) out-
ward until the screws contact the surface of the turning (B) (Fig. 81), and firmly tighten locknuts (H).
Mount the workpiece between the lathe centers and lock tailstock in position on the lathe bed. Adjust the tool advancement
arm (K) Fig. 82, so the follower arm (G) is against the largest diameter of the turning (B) Fig. 82. Pull spring handle (L) back and
move the tool advancement arm (K) back one notch (1/8"). With the tool bit (M) clear of the workpiece, apply power to the lathe.
Move the duplicator carriage (N) to the right two or three inches and engage tool advancement arm (K) to make the initial cut
to round off the workpiece. NOTE: When a flat surface is needed at the ends of the final cut, move the carriage (N) left and
rough cut up to the flat, and then to the right to continue the rough cut. This action will keep the wood from splintering.
Once the workpiece has a round surface, place a steady rest (P) Fig. 83 on the work to avoid vibration. Continue advancing the
cut in 1/8" increments, using the spring handle (L), tool engagement levers, and fine adjustment knob (R) to follow the contours
of the turning. IMPORTANT: Always pull back on handle (L) before advancing tool engagement lever (S).
When turning a workpiece of varying diameters, start the follower arm (G) Fig. 83 on the largest diameter and work down to the
smaller diameter.
Perform final operation by moving carriage (N) Fig. 83 and sanding workpiece.
