Holtey Classic Hand Planes
Where precision toolmaking becomes art
precision engineering without compromise
Making the dovetailed A27 Bullnose plane
This is the dovetailing on the bottom which is done in a pair so I can work them back to back which is much easier for programming.
When the dovetailing is completed on the bottom I machine a shoulder which provides better support to the sides and is a 'light stop'.
This is the main metal infill for the A27 which has a complex contour so with the limitations of my milling machine I mill on both sides by turning it over
to the other side which is then mirrored. With careful setting it works out perfect.
This shows the different stages of machining the metal infill from a solid block and the rest speaks for itself.
The naval brass side after profiling and chamfering. Using a fixture plate which I make for all the different plane sides.
After the profiling and chamfering the throat can be routed out by adding another clamp to the existing fixture for extra support.
Showing the sides after milling with all the mess cleaned away and looking pretty.
The main structural components ready for final assembly.
Bullnose infill shown in Boxwood and Ziricote, they are made in a folded pair waiting for the diagonal cut to separate them.
