Copying lathe

[2] Nartov's lathe duplicated the pattern from a template to a blank, cutting to the preset scale.

The cutter was set on the same axis as the probe, but was controlled by the screw with the smaller step, which ensured the scaling.

[3] Blanchard's copying lathe traced a model to turn gun stocks, producing the desired contour automatically.

[4] Originally used for gun stocks, it was subsequently used for numerous objects of irregular shape: piano legs, wig stands, shoe lasts, etc.

In Blanshard's copying lathe a rotating template controlled the cutter which cut the blank rotated in unison with the pattern, while the pattern tracer and the cutter moved along the horizontal axis.
