ALIGNING REELS IN THE HORIZONTAL PARALLELISM
(CONTINUED)
6. To adjust reel position first determine the direction the
reel has to move for alignment. The direction that the
reel will have to be moved can be determined by pulling
back on the dial indicator stop bar and if the dial moves
back to the "0" position you will have to move the reel
towards you. If that cannot be done the reel will have to
be moved away from you.
7. There are two adjusting steps for final positioning of the
reel as follows:
A. With the reel set gauge still in the left hand side of
the reel, turn the horizontal adjusting handwheel (FIG.
54) in the direction required to match the initial indicator
reading on the right hand reel position. See FIG. 51.
B. Now continue to turn the handwheel to travel
farther by the full amount already traveled.
EXAMPLE: If the reel center shaft is off .085 right to left,
turn the handwheel from .085 to zero and then continue
to turn until it reads .085 additional on the other side of
zero.
The reason for this is that the square mounting bar
pivots on one end and is adjusted on the opposite end.
Anytime the adjusting end is moved to change the left
side dimension, the right side dimension is also changing
at a ratio to the left side. By over compensating at the
adjusting end you will compensate for this movement and
get the reel aligned much faster.
8. Now move the set up stand back to the right side of the
reel. Set indicator rod on the same spot you used the first
time and reset large dial on "0". Make sure you read the
setting on the small scale and note. Then proceed with
paragraph STEPS 5 and 6 again. When you have done this
procedure a few times you will find this procedure will
become very easy.
IT IS ESSENTIAL THAT CARE IS TAKEN WHEN
SETTING THE REEL UP IN THE HORIZONTAL
POSITIONS IN ORDER TO GRIND IT INTO A
CYLINDER SHAPE. ANY MISALIGNMENT WILL
CAUSE YOU TO GRIND INTO A CONE. SEE FIG. 56.
9. Repeat STEPS 6 and 7 until the horizontal parallelism
has been adjusted to within .003" (.076 MM) end to
end. Then tighten the horizontal lock handle, and both
side lock knobs. See FIG. 54 and 55. When tightening
the knob it is very important that you have the dial
indicator located at that side of the reel and watch it as
you tighten. It must not move in the tightening process.
After both knobs are tight, recheck alignment.
