center enters the chamfered hole in the end of the
work piece and you can just barely feel the center
touching the bottom of the hole in the work piece°
The small nut "B" should still be against the tail stock
framer (If it is not, you have turned the tail stock
center in too far). With the nut "B" against the tail
stock frame and the tail stock center just touching the
end of the work piece, tighten the large wing nut
("C") firmly with your fingers. Do not over tighten as
it is not necessary and could possibly bend or damage
the tail stock assembly This procedure has locked the
tail stock center in position with the work piece held
firmly between the head stock drive spindle and the
tail stock center
You should now be able to rotate the work piece freely
by hand. If, when you rotate the work piece by hand,
it feels tight rather than free 1o turn, loosen the nut
"C" slightly and back the tail stock center screw "A"
out about 1/8th of a turn and retighten the wing nut
"C" snugly. Fig. 7 If, however, after you snugged up
the wing nut "C", the work piece feels loose and
sloppy on the tail stock center, the nut "C" should be
loosened and the tail stock screw "A" should be
turned about 1/8th of a turn toward the work piece
and nut "C" retightenedo
The correct conditions are:
1 Nut "B" is resting fiat against the tail stock frame.
2. The work piece seems to be supported firmly
between the tail stock center and the head stock.
3o The work piece is free to rotate easily by hand°
"ROUNDING UP" _ TURNING FROM
SQUARE TO ROUND
BE SURE THE ROUTER POWER CORD IS DISCON-
NECTED FROM THE ELECTRICAL OUTLET°
To do the rounding of the portion desired, the use of
a Craftsman Rabbetting and Surfacing Bit number
9 26310, which is used with _g2589 Arbor and Pilot
Set, must be used. The arbor and bit only are used°
DO NOT USE A PILOT IN THE CUTTER BIT. Adjust-
able "stops .... H" (Fig. 5), are provided to limit the
permissible travel of the router carriage both toward
the head stock and toward the tail stock The stop
nearest the head stock shouid be positioned and
tightened to prevent the router bit from being moved
beyond the desired end of the round portion of the
work piece° The stop nearest the tait stock should be
positioned out of the way--as far to the left as it
can be set--if the work piece is to be round all the
way to the left end of the work piece. (if it is desired
that only a middle portion of the work piece be round
and a portion left square on both ends, then the left
stop should be positioned accordingly to limit the
movement of the router bit to the left)
Before starting the actual cutting, the cabfe (K) should
be disconnected from the cable clamp (N) and the
cable drum should be turned so that the spring (L)
in the cable is positioned as near the tail stock as it
will go. Fig. 5 (This is only to get the spring out of
the way because the cable is not used in the "round-
ing-up" operation) The cabte drum shouid then be
clamped to the head stock frame by tightening the
w_ng nut "A" in Fig 3 Putl the index pin knob "A"
(Fig 4) out and rotate the knob 1/4 turn so it will
remain in the out position when you let go. Now
position the bottom of the router bit as shown in Fig
9 Set the feed clown screws "F" (Fig 9) so that they
just barely touch the front bar and lock the screws in
position by tightening the wing nuts "G" (Fig 9) firmly
With the router carriage off to the left, near the tail
stock (or lifted up out of contact with the work piece),
rotate the drive spindle 1/8 of a turn as in Fig 10 (this
is 3 numbers on the graduated drive spindle) and then
pull back slightly on the index pin knob "A" (Fig. 4),
rotate the knob 1/4 turn and push knob back in_ This
is to engage the index pin in a locating hole in the
