It’s actually easy to do this, spotting (perlage), but extremely challenging to do actual engine turning (guilloche). The machines that are specifically designed to do this rely on the fact that the machine spindle is not perfectly perpendicular to the work surface by only fractions of degree. There are specialized machines within the watchmaking community that are quite rare designed to do this on watch movements and watch cases, and they use typically a wooden dowel turned to the diameter of the peralage spot you want to make, charged most often with diamontine ( diamond powder) of varying mesh sizes, usually around the equivalent of 300 grit I believe, or finer. It can be done many ways but it’s pretty much the same- either an abrasive pad or wire cup wheel in a drill press milling machine or even hand drill. Technically what this technique is called among horologists and ornamental turners is “spotting”, aka perlage. If you’re interested in this topic there is actually a society for this in the US, the Society of Ornamental Turners: īrittany Nicole Cox of Memoria Technica in Seattle does several classes a year with him teaching beginners real engine turning and it’s quite reasonably priced. He runs a wonderful newsletter you can sign up for that covers the real deal at his website. I don’t own a rose engine (aka guilloche lathe), but I have actually done real engine turning (guilloche) on an actual rose engine for an afternoon with the US expert David Lindow. Posted in Tool Hacks Tagged aluminum, Engine turning, jeweling Post navigation If anyone out there feels like putting a pencil in the collet of a CNC router, we’d love to see the results. The trick to engine turning comes in getting a consistent pattern on the piece, something that could easily be done with a CNC machine. Yes, the tools are a bit more expensive, but you’re still looking at a somewhat soft tool scraping a fine abrasive into a piece of metal. This is, incidentally, exactly how engine turning and jeweling are done in the real world. It’s just a matter of putting circles on the aluminum after that. Toothpaste is spread over the piece to be turned, and a pencil is put in the chuck. The only other required components are a number 2 pencil, some toothpaste, and any sort of rotary tool, in this case a drill press. The process begins with a piece of aluminum, in this case an aluminum Open Source Hardware logo. decided to explore this technique and ended up getting good results with a pencil eraser and toothpaste. You see it on fine watches, and you’ll see it on art-deco metal enclosures. Engine turning, or jeweling, or guilloché, or a whole host of other names, is the art of polishing a pattern of circles on a piece of metal.
