Sanding And Finishing; Changing Spindle Speeds; Headstock Spindle Lock; Headstock Rotation - Jet JWL-1442 Mode D'emploi

Fig 13
Mount the workpiece (A, Fig 14)
directly to the face plate using 4 wood
screws (C) from the back. Be careful
to use screws short enough not to
interfere with the cutting process but
long enough to hold the workpiece
securely to the face plate.
Fig 14
If screw mounting is not allowed at all,
the work may be glued to a backing
block (D) and the backing block
screwed to the face plate. A piece of
paper in the glue joint will prevent
damaging the wood when separated
later.
Mount the face plate with the
workpiece already attached onto the
spindle nose thread and hand tighten.
Move tailstock away, remove centre
from tailstock to prevent injury.
Turn the workpiece by hand to see if it
rests securely and can be rotated
freely.
For face plate turning the tool rest is
set slightly lower than centreline.
Caution: cut with your chisel on the
left side of the turning centre only.
Try to make one, very light continuous
movement from the rim to the bottom
of the bowl to ensure a clean,
sweeping curve through the
workpiece.
Use left hand to control cutting edge
of gouge, while right hand swings tool
handle around toward your body (Fig
15).

Move tool support to the exterior to re-
define bottom of bowl.

6.6 Sanding and Finishing:

Remove the toolrest and begin with a
fine grit sandpaper (120 grit) and
progress through each grit, using only
light pressure.
Use power sanding techniques to
avoid concentric sanding marks.
Finish sanding with 220 grit.
Apply first coat of finish. Allow to dry
before sanding again with 320 or 400
grit sandpaper.
Turn lathe back on and make a
separation cut through the base. Stop
at about dia. 80mm and use a fine
tooth saw to separate the bowl from
the waste.
Apply additional finish coats and allow
to dry before buffing.
7. Setup and adjustments
General note:
Setup and adjustment work may
only be carried out after the
machine is protected against
accidental starting by pulling the
mains plug.

7.1 Changing spindle speeds

The speed selector (J, Fig16) selects
one of eight available speeds.
Select desired speed by pulling handle
and turning left (lower speeds) or right
(higher speeds).

Fig 16
Caution:
Never change speeds without the
motor running. Damage to the
variable speed pulleys may result.

7.2 Headstock spindle lock

Push in pin (G, Fig 16) to keep the
spindle from turning.
Caution:
Never press the spindle lock while the
spindle is turning!

7.3 Headstock Rotation

Unscrew the index plunger (F, Fig 17)
counter clockwise.
Loosen the headstock lock handle (E)
and pull the index plunger (F) to turn
the headstock.
Fig 17
For larger workpieces the head stock
will have to be turned 90° , the
extension added to the tool rest.
Caution: always operate lathe with
the headstock locked in position.
The headstock can be positioned
anywhere along the machine bed.
