Q: What does this shaft clamp do?
It lets you lock the relative position of the dual marking gauge's cutters while still being able to freely adjust the fence for offset.
Veritas Dual Marking Gauge & Shaft Clamp Set

Designed to fit onto the Veritas dual marking gauge's guide rods, this shaft clamp lets you lock the relative position of the cutters while still being able to freely adjust the fence for offset. This allows you to preserve identical mortise or tenon sizing when joining parts of different thicknesses or when adding a reveal, since it prevents the cutter settings from shifting while the fence is being repositioned.
Machined to precise tolerances to prevent binding on the rods, the 1/2" long collar is made from extruded aluminum, with a turned brass thumbscrew that tightens onto the marking gauge's steel guide rods without marring their surfaces.
Made in Canada.
