Sanding And Finishing; Setup And Adjustments; Changing Spindle Speeds - Jet JWL-1840EVS Gebrauchsanleitung

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.
If reversing spindle rotation, make sure face plate, chuck or
other work holding is secured with the set screws, to avoid
threading loose.
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.
Position the tool rest as close to the workpiece as possible.
Tighten locking handles.
For face plate turning the tool rest is set slightly lower than
centre line.
Caution:
Cut with your chisel on the left side of the turning centre
only.
Use left hand to control cutting edge of gouge, while right
hand swings tool handle around toward your body (Fig 29).
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.
Move tool support to the exterior to re-define bottom of
bowl.

6.6 Sanding and Finishing

Remove the tool rest 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 drying 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

Disconnect lathe from power source !
Loosen the locking screw and open the belt cover.
Loosen pivot lock handle (A, Fig 30).
Lift up on the tensioning handle (B) to remove tension from
the Poly V-belt.
You can now position the belt in the desired speed range
(Fig 31).
Be sure that Poly-V belt seat properly in corresponding
grooves of pulleys.
