Red- the original copy lathe I saw was a leftover, WW2 machine, made to carve rifle butts (303), it had a bed, as big as a small bedroom, and had a cutting head similar to this, but the teeth were about 2" inches across, evil bit of machinery, never saw it working though - If you know a gun manufacturer (or cricket bats), it would be well worth a look, to see how it all works. pete
