Chuckle, thanks for pointing that out Dave. The main reason for not using the lathe is the difference in reaction forces of the lathe using a slowly moving tool in constant contact vs a 20,000 rpm engraving bit is the reason for wanting to use the 20,000 rpm tool, not to mention the moving engraving bit will leave a much smoother surface that a good stiff brush full of warm carnaba will lube virtually forever. Cutting it on the lathe will likely cut it 2+ mm fat in the center of the z span because of that difference. Take care and stay well.
