Hi Brian,

Where can I see these pix? Here are the Elliott diagrams, with photos linked from the text:

Is quantifiable metal loss confirmed by weight (Not that I think that is possible.)? I don't know of any attempts to do this.
or just shape of object.

IE is the blade deformed showing less material or is material really missing? I believe it's inferred by the registration of the camera to a minute mark or recognizable feature on the blade, and overlaying the successive images. Maybe Steve can help here. Kato and Kawai likewise have made photographic registration and measurement, though surely using more expensive gear. On the face of it, then, I suppose you could say, 'well, maybe the steel compressed, since no weight comparisons were made, or spalled-off particles collected'. On the other hand, steel is a crystalline lattice, through and through, and I don't believe density differences have been detected after rolling under great pressure--the rolling just results in elongation, not compression to higher density. However, I'm only reporting what I've read, and don't know any more than you, and could easily know less.

If it is missing where did it go? Dunno.

Did metal particles get found in the planing/chiseling? Dunno.
