We are not talking about polishing, we are talking about the process of enlarging a borehole.
Stocks claims that the borehole can be enlarged through a narrow neck using a stick an stone.

Production procedure. Stocks claims that the stone is inserted through the narrow neck and then laid flat.
If the stone can be laid flat then the borehole is already at the minimum diameter that can accommodate the alleged cutting/enlarging stone laid flat. Unless of course the stone can somehow magically expand while being rotated. (which is why today we have centrifugal, expanding honing tools).

Yes I do. Again we are referring to Stocks claimed bore expansion method irrespective of materials.

I said "Irrelevant".
You appear to be arguing with yourself again, hallucinating?? Who mentioned relative hardness?
You are deflecting again. The issue in this case is one of technique, not materials.
How is the cutting stone able to expand after insertion through the narrow neck and thus enlarge the inside of the vessel.???
