Here’s how the process works for picking up a reference roll: (keep in mind that using the L-742W or L-
732W is like having two walls, both perpendicular to each other, 100 ft. (30.5 m) in radius and very flat).
1.
Place the L-742 on the L-106 stand outside
the machine near the reference roll, at the
side of the machine and level it. The L-
742 Laser Plane #1 (LP#1) should be
about 5 in. from the side of the roll to
allow space for the A-1519-2.4ZB Targets
to measure the roll.
2.
Place A-1519-2.4ZB Target #1 on the
reference roll horizontally at the closest
point to the laser and mark the location on
the roll. Slide the magnetic base slowly
up/down (or rotate the roll) until the
bubble is centered on the bulls-eye level.
This puts the target at the Top Dead Center
(TDC) of the roll.
