Spiers Style Shoulder plane – 2
Difficult to define a name for this component; It certainly is a bush and it is threaded into the plane’s bridge which will also hold down one end of the front infill through the horn. This component also has an internal thread for the thumb screw that clamps the wedge. The picture shows a temporary screw driver slot being cut which will be removed after assembly.
This picture shows the bush as described above being bored through the centre ready for the internal tapping. The diameter at the shown end has been reduced slightly so it leaves a step at the other end which works through the counter bore in the infill so it holds it down tight on the bridge.
Tapping the internal bore.
Showing the above mentioned components complete. You can see the hold down shoulder with its temporary screwdriver slot.
Forming rivets in situ for the fixing of the bridge.
Whilst some other fixtures remain on the CNC mill it is prudent, with some modification to the programme to form the contours of the front infill, including throat. This allows me to make the exact allowances for fitting.
The adjuster recesses are also CNC machined. The quality of work using this system is unrivalled. It is so crisp and clean, unlike those that look like they have been gnawed by a rat.
Showing most of the components now ready for temporary assembly. It is necessary to do some work in situ then dis-assemble for some hand work including polishing and shaping to the wood work.
The shape of front of the mouth (shown on the this plane and the 982) is really nice. Is the same cutter (which is also impressive) used for both?

Karl they are beautiful planes. You are killing me by making me wait to see you put a finish on one of these beauties.
I know it is going to be worth the wait. A friend from Wisconsin. John

I see it differently. A famous exchange between a sculptor and his patron ran as follows:
Patron: Monsieur, it simply amazes me that you could start with a block of ordinary marble and fashion from it such a magnificent figure!
Sculptor: But Madame, the figure was in the marble from the beginning. God put it there. I merely removed the chips and slabs that concealed it from your eyes.
To me, this speaks volumes…particularly about the supreme importance of humility.
Food for thought.

Hi Craig
If I understand you correctly the answer is no. The form on the toe section of the No 982 is done with two different cutters and then hand finished. However, on the shoulder plane it is done with an ordinary tungsten carbide cutter and the contour is side milled with the CNC mill.
