Headstock Spindle Index - Jet JML-1014I Operating Instructions Manual

Fig 4
Open the access door (A, Fig4) at the
left of the machine base and at the
back of the headstock (B, Fig 5).
Fig 5
Take tension off the belt (E). Loosen
the motor plate lock (C) and lift up
motor plate handle (D).
Fig 6
Move the belt to the desired spindle
speed (speeds see access door).
Tension the belt.
Close the access doors.
7.2 Adjusting tool rest
Position the tool rest ( C, Fig 7) as
close to the workpiece as possible.
Tighten handle (A, Fig 7) to lock.
Fig 7
Set the height to appr. 3mm above
centre. Tighten indexable knob (B, Fig
7).
7.3 Installing work holding
Disconnect the machine from the
power source (unplug)
The face plate (A, Fig 8) screws on
the spindle nose thread.
Fig 8
Mount the workpiece directly to the
face plate using 4 wood screws 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.
If screw mounting is not allowed at all,
the work may be glued to a backing
block 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.
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: always cut with your chisel
on the left half of the workpiece only.

The spur drive centre (A, Fig 9)
locks into the spindle taper and can be
removed with the knockout rod (B, Fig
9).
Fig 9
Mount the workpiece between the spur
drive and the tailstock live centre.
Turn the tailstock hand wheel until the
live centre well penetrates the
workpiece. Reverse the hand wheel by
one quarter turn and lock the tailstock
spindle.
Turn the workpiece by hand to see if it
rests securely between centres and
can be rotated freely.
For turning between centres the tool
rest is set appr. 3mm higher than
centreline.
7.4 Adjusting tailstock
Turn the hand wheel (A, Fig 10)
clockwise to move tailstock spindle
forward. Lock spindle with the
indexable knob (B, Fig 10).
Fig 10
The handle (C, Fig 10) locks the
tailstock in position on the bed.
The live centre can be ejected by
turning the hand wheel counter-
clockwise.
The live centre pin can be removed to
allow deep hole drilling operations.
