4-24 Setting Up and Using Laser Alignment Fixtures
Attaching Excess Chain
One of the problems with using chains as a mounting bracket is that the
excess chain flops and can cause errors. UltraSpec laser alignment fixtures
provide solutions for this problem.
Two slots are provided (one on either side) to take up the slack. As shown
in the following photographs, you can use either or both of the slots as
needed. The order of use is not important. In fact, the L-slot cannot be used
when mounting to shafts (or couplings) greater than 3 inches (76 mm) in
diameter. When fastening the chain into the T-shaped slot, the rubber block
will hold the chain in place.
The photograph below illustrates using the T-shaped slot; use of the L-
shaped slot is shown on the next page.
