The so-called Blanchard lathe [actually, it’s a shaper since the cutter is a rotating wheel] works much like a modern key-cutting machine with a stock blank [a rough gunstock form] in place of the key blank. An iron master form, in the shape of the musket stock, slowly rotates allowing a guide wheel to roll over it and to direct, in turn, the cutting wheel as it makes identical movements on the rotating wooden stock blank.

Here's Hartley Peavey talking about how they came up with the idea and what it was to implement it in guitar manufacture.
