4-46 Setting Up and Using Laser Alignment Fixtures
Introduction to Special Applications
This section covers using additional mounting blocks and mounting on
large diameters (> 8 inches). Normally, additional blocks are used to
achieve greater coupling clearance however, in some cases, you may find
that one (or both) of the mounting blocks must be installed on the coupling
itself. For larger diameter shafts (or mounting on a coupling), additional
lengths of chain may also be needed to mount the base.
