CHANGING LATHE SPEEDS
To reduce the risk of injury, do not
operate lathe with pulley cover door open.
For the 46-455 lathe, the lathe speed is determined by
one of five pulley sets (See Changing Pulleys section
below.) The pulleys with the 46-455 lathe provide five
different speed settings: 500, 950, 1550, 2700 and 4000
RPMs.
The 46-460 lathe is equipped with electronic variable
speed control. Changing among the three pulley sets
(see Changing Pulleys section below) determines
the lathe's speed range and a control knob dials the
speed up or down within that range. The pulleys with
the 46-460 lathe provide three different speed ranges:
250-750 RPMs, 600-1800 RPMs and 1350-4000 RPMs.
CHANGING PULLEYS (46-455 and 46-460)
To reduce the risk of injury, do not
operate lathe with pulley cover door open.
To move the belt between pulleys:
1. Lift up pulley cover (X) Fig. 14.
2. Pull down belt tensioning lever (Y) Fig. 15 to release
belt tension.
3. Open lower side door (AA) Fig. 16 and move belt to
desired pulley set according to the speed chart on
inside of pulley cover (X) Fig. 14 NOTE: Be sure the
grooves on the inside of the belt (BB) Fig. 17 fully
engage the grooves (CC) on both pulleys and that
the belt does not hang off the edge of the pulley.
4. Lift belt tensioning lever (Y) Fig. 15 up until it snaps
into place.
5. Close both the lower side door (AA) Fig. 16 and the
pulley cover (X) Fig. 14 securely.
To adjust belt tension:
SPEED RECOMMENDATIONS FOR MIDI LATHE
The following guidelines are approximate
and must be reduced if the piece you are working on
is out of balance. These speeds are only for side grain
pieces. Reduce speed and take special care when cutting
end grain.
