Selecting Feed Drive Direction - Rotor or Drum
Selecting the rotor setting allows the crossfeed to move in and
out – moving the tool bit across the face of the rotor. Selecting
the drum setting allows the tool slide to move left and right –
moving the tool bit into and out of the drum. Always select set-
ting with the feed drive disengaged. Familiarize yourself with
the settings and movement of the feed:
1. Move the feed engagement lever down to disengage the
feed.
2. Select the rotor setting by pressing the button in the cen-
ter of the handwheel and moving the entire handwheel inward
toward the lathe. It will seat into position and “pop” the button
back out.
3. Turn the handwheel and notice the direction of feed travel.
Turn the handwheel clockwise to move the crossfeed inward
toward the lathe – into the center of a mounted rotor. Turn the
handwheel counterclockwise to move the crossfeed away from
the lathe – to the outer edge of a mounted rotor.
4. To select the drum setting, press the button in the center
of the handwheel and pull the handwheel out. It will seat into
position and “pop” the button back out.
5. Turn the handwheel and notice the direction of feed travel.
Turn the handwheel clockwise to move the tool slide to the left
– into the center of a mounted drum. Turn the handwheel coun-
terclockwise to move the tool slide to the right – out of a
mounted drum.
Note: Look for this plate on the lathe. It has been placed on the
unit to assist you while working with the lathe.
Notice also that rotor and drum positions are indicated on the
handwheel with arrows pointing inward and outward.
