AH-3 / AH-3T Arch Hold Downs
A Woodworking Hold Down Youve Never Seen Before!
Almost every woodshop has some Hold Downs (or Holdfasts) because they are essential to secure the workpieces in place for safe operation. Hold Downs have been around for centuries, but mostof themstill need to be satisfactory. One of the flaws of the regular hold downs is that they are designed in deformable Cantilever Structures. When holding force is applied, the clamping point will produce excessive tilting displacement due to the bending deformation of the structure, which obviously will undermine the holding securityand damage the workpiece surface. In addition, becauseof the overturning bending momentunder loading, the hold down pillar shaft continuously damagesthe workbench dog holes. So it has been Harveys aspirationto design a better hold down for woodworkers.
Inspired by the ancientwisdom of Arch Building Structures, Harvey team came up with a completely new structural design for hold downs, called AH-3 Arch Hold Down. With the unique Archshaped frame, the AH-3 is able to firmly hold workpiece down with no tilting deformation. And it features a balancing leg which provides adaptive full balance to the working leg to eliminate any overturning moment on the pillar shaft. Also its innovative Quick-Release Pressure Knoband Toolless Workbench Installation Mechanismallow you to clamp your workpiece ideally with joy!
Besides the AH-3 Arch Hold Down, Harvey also created the AH-3T model the version for T-slots mounting application.
