Bit for cuttting geneva waves




is there a bit for a routing tool that is specifically designed for cutting out geneva waves, or is this something that is typically custom made?

^_^:
...it's a wooden disk, fairly shallow (think flying saucer shaped), that is held at an angle to the surface. The parts being decorated are held in a jig to ensure proper alignment.
In other words, Geneva waves are very much a surface feature - they are barely discernable to the touch.

Is this a disk that would be made by the watchmaker or are they commercially available? I assume that the disk is somehow fastened to a lathe or router of some sort...I have managed to polish a beater movement and am going to begin experimenting on it for engraving, geneva waves, and the brushed circles (I don't know what they are called). Do you recommend any specific books or resources for this?
Thanks, TC

...as the photos I've seen of the process generally are from factory visits. As such, details of how one obtains these disks and the details of the machines that apply them aren't available most of the time.

You said it is a shallow UFO shape, about what are the dimensions? All I have ever seen of wave-making was a Grand Seiko video a post linked to, and there it looked like they were using a shallow router bit that removed material to a perceptible depth. I would like to try experimenting with the wood disk though, it seems like that would have less permanent results. I imagine a dremel on a press at an angle would suffice to hold the disk, and use a sliding stage of some sort to move the piece below it. what about brushing circles on a plate, is this something that could be done with pegwood in a dremel?

^_^:
...1.5-2" in diameter, and about 0.5-0.75" thick. The edge of the disk was what was rubbed against the surface.
As for perlage - pegwood, dremel or drill press, and perhaps some abrasive compound for the tip.
