The A7 Infill Dovetailed Shoulder Plane.

The Shoulder plane was difficult enough to make and adding the adjuster compounds the construction work. It needs a clamping system which was a retrospective design.

To make this clamping arrangement required a nut/bush for the clamping screw, which had to be integrated with the bridge. This is stronger and aesthetically enhanced with the use of a raised horn in the infill. To get this correct is a true test of craftsmanship.

I have improved the adjuster by making the traveller section (often referred to as a banjo) all in one piece, including its drive spigot which is perpendicular to the blade.
