Adjust gear to mesh with upper and
lower gear.
Placing ordinary paper in between
gears helps to adjust for correct gear
spacing (… remove the paper
afterwards!).
Close and lock the pulley cover.
7.2 Turning between centres
Mount the work piece fitted with the
drive dog between centres.
The driver is driven by the face plate
(Fig 14).
Fig 14
Lubricate the tailstock centre with
grease to prevent tip from
overheating.
7.3 Taper turning with tailstock
Turning up to a side angle of 5° can
be achieved by off-setting the
tailstock.
To offset the tailstock, loosen the
locking screw (1, Fig 15), loosen the
front adjusting screw (2) and take up
the same amount on the rear
adjusting screw.
Tighten the adjusting screws and the
locking nut to hold the tailstock in
position.
The work piece must be held
between centres and driven by the
face plate and drive dog.
Fig 15
After taper turning, the tailstock
must be returned to its original
position.
Turn a test piece and adjust until the
machine turns a perfect cylinder.
7.4 Taper turning with top slide
By angling the top slide, tapers may
be turned.
Loosen two nuts (1, Fig 16) and
rotate the top slide according to the
graduated scale.
Fig 16
The top slide may be located in two
positions on the cross slide.
7.5 Three jaw universal chuck
With this universal chuck,
cylindrical, triangular and hexagonal
stock may be clamped (Fig 17).
Fig 17
To hold big diameter stock, a set of
3 OD chuck jaws is supplied.
The jaws always need to be inserted
to the chuck in the correct order.
Use Molykote Paste G (or adequate
grease) to lubricate the jaws.
7.6 Four jaw independent chuck
This chuck has four independently
adjustable chuck jaws (Fig 18).
These permit the holding of square
and asymmetrical pieces and enable
the accurate concentric set-up of
cylindrical pieces.
Fig 18
7.7 Live centre (optional)
The live centre is mounted in ball
bearings.
Its use is highly recommended for
speeds above 500 RPM.
Fig 19
To eject the live centre, fully retract
the tailstock quill.
7.8 Steady and follow rest
The steady rest
serves as a support for longer shafts
and ensures a safe and chatter free
operation.
The steady rest is mounted on the
bed way with a locking plate.
Tighten knurled screws (3, Fig 20)
so that fingers (2) are snug but not
tight against work piece. Tighten
nuts (1).
Lubricate the fingers to prevent
premature wear.
