Sanding And Finishing; Setup And Adjustments; Headstock Spindle Lock - Jet 4224B Mode D'emploi

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 27).
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 to dry before buffing.
