The Grandwork Hammer Squares stand on a Squaring Platform to indicate the verticality of grand hammers at strike. The Hammer Square Orginal is a one-piece design, with inside walls of legs as references. The Articulated Hammer Square has legs that turn in, employing leg edges as references and bringing them closer to the hammer being gauged. The Extended version helps blind technicians feel both hammer and reference. And the Hammer Square Lite is for tight spaces, as when hanging hammers.
Grandwork tools and protocols allow all to succeed at grand regulating, guiding the inexperienced and empowering the experienced.
