OPERATION
INDEX STOP FINGER ADJUSTMENTS
The FINGER AND BODY ASSEMBLY includes two
fingers. See FIG. 36. When relief grinding, the
movable INDEX STOP FINGER moves from the
RELIEF FINGER SIDE (back side) of the reel blade
when traversing from right to left, to the grinding
wheel side (front side) of the reel blade when
traversing from left to right. This feature allows
the reel to index to the next blade, automating the
grinding process. It is important to have the INDEX
STOP FINGER adjusted properly.
STEP 1: When the grinding head is positioned with a
reel blade resting on the FIXED RELIEF FINGER high
point, the INDEX FINGER should have about 1/32" [.8
mm) to 1/16" [1.5 mm] of free play behind the reel
blade. The INDEX STOP FINGER is spring-loaded to
the UP position. To check for free play, push down
on the INDEX STOP FINGER. Use the INDEX STOP
KNOB to adjust the stop position of the index finger.
If there is too little free play, rotate the INDEX STOP
KNOB counter-clockwise. If there is more than 1/16"
[1.5 mm] free play, rotate the INDEX STOP KNOB
clockwise.
The INDEX STOP PIN on the end of the INDEX FINGER
is adjustable. It should be adjusted to catch the reel
blade and still leave enough clearance to the reel
spider after the relief is ground to the depth required.
NOTE: The reason for the 1/32" (1 mm) clearance is
so the high point of the Relief Finger is acting as the
guide during the relief grind cycle. The INDEX STOP
FINGER acts as a guide onto the tapered ramp of the
Relief Finger.
STEP 2: With the down limit of the INDEX STOP
FINGER properly set, you may have to adjust the up
limit of the INDEX FINGER for 5" (127 mm) diameter
reels with reverse helix blades. The up travel limit
is restricted to keep the INDEX FINGER in the reel
blade index path to properly catch the next blade
when indexing and to allow clearance between the
back side of the INDEX STOP FINGER and the front
side of the blade when the grinding carriage is making
its return trip to the home position. If the INDEX
STOP FINGER has problems catching the next blade,
turn the INDEX FINGER T-KNOB counter-clockwise.
If there isn't enough clearance between the back side
of the INDEX STOP FINGER and the front side of the
reel blade, turn the INDEX STOP FINGER T-KNOB
clockwise. See FIG. 36.
Adjust the T-knob in by 1/8" (3 mm) into the hole
opening so the up travel is restricted. Check the up
and down swing of the INDEX FINGER for clearance
on both sides of the reel blade for the relief grind.
