There is evidence
(a complete machine) of a complete two person lathe from Egypt c
1430 BCE. |
There has been a
similar but smaller and less complete machine excavated in
Sumeria. As far |
as I am aware,
there is no evidence that ancient Chinese or Indian craftspeople
used lathes. |
But Stuart King,
an English expert on older technologies, is not alone in the
considered opinion |
that the symmetry
of too many Chinese artifacts could not be achieved without
rotational force. |
Leather and wood
preserve poorly, but perhaps in some as-yet unexcavated tomb at
Xian ... |
Usually, with
Chinese sword (jian) handles the shape is NOT circular because
an oblong shape |
helps you
understand where the cutting edges of the blades are. You wish
to avoid a flat hit. |
Correct
orientation is even more important with a saber (dao) because it
has just one edge. |
