The Squaring Platform Lite is designed to regulate the verticality of a grand action section by section. It functions exactly like the full action Squaring Platform, except that it is only 21" wide. Adjust the legs so it just clears backchecks at rest and use the depth/angle gauge to true up the four corners. The sliding top is contracted over the base for traveling shanks to vertical with a Shank Traveler and extended over the backchecks for squaring hammers to vertical with a Hammer Square.
