OPERATING INSTRUCTIONS
CHECKING REEL FOR CONE SHAPE, REEL
ROUNDNESS, AND STRAIGHTNESS OF REEL
OUTSIDE DIAMETER.
BEFORE GRINDING--
A.Before storing the set up gauge, it is very
effective to use it to check the ungrounded reel to
determine the amount the reel is conical in shape
and which end has the larger diameter. See FIG.
56. Start with the set up gauge at the right end of
the reel. Loosen the knob on the indicator stop
bar, holding the indicator rod firmly against one
blade. See FIG. 53. Pull the indicator stop bar
back until it clears the plunger then advance it
forward until it contacts the plunger and advances
it 1/2 inch further. Lock in place. This sets the
plunger at its midpoint and allows adequate
movement in both directions. Set outer dial at
zero and note position of pointer on small dial.
B.Now move it to the left side of reel and indicate
the same blade. From the reading determine
the amount the reel is cone shaped. This also
determines high point for grinding. Grinding of a
reel must always start at the high point.
AFTER GRINDING--
1. After grinding a reel, check the roundness
on each end of the reel and center before
removing ground reel. See FIG. 57. Loosen
the knob on the indicator rod firmly against
one blade. Pull the indicator stop bar back
until there is a 1/32" (.8 mm) gap between it
and the set screw. This is to permit rotation
of the reel blades to ride on the domed anvil
only. See FIG. 58. At each location (left, right
and center) turn the reel by hand and observe
the indicator variations. All readings should
be within .002" (.05 mm).
2. Straightness of reel outside diameter--Take
indicator readings at both ends of reel.
Compare readings between each end of reel
for straightness. All readings should be within
.002" (.05 mm).
3. Carefully remove the setup gauge and store it.
