I must be missing the difficulty. It looks to me like you could turn those dovetails on a lathe. You cut them into round stock before sawing it in half and facing. The female dovetails are done directly on the OD of the round stock. For the male dovetails, it would require mounting the work offset (eg. on a faceplate); alternatively, you could do it more awkwardly on a mill with the tool offset in the spindle like a boring bar. Either way, it could be done with manual machines.
- doubleg72 3y agoExactly.. turned on lathe, millwork if not 5 axis, hardened, and then ground to finish.
- userbinator 3y agoThe male dovetails might've been made with something resembling a hole saw, but with the teeth angled appropriately.
- mdorazio 3y agoThat's fine for the outer pieces, but the ones they mount into have dovetails on both inner crescents. I can't see how you could turn those on a lathe without some weird offset going on.

- genter 3y agoWell, yes, that's what you do. It's called eccentric turning. With that much of an offset, a normal chuck wouldn't work, you'd have to use a faceplate. http://www.steves-workshop.co.uk/tips/lathetech/eccentrics/eccentricindex.htm http://www.steves-workshop.co.uk/tips/lathetech/eccentrics/e...
- mdorazio 3y agoThat explains it! I didn't know about faceplates - thanks for the info.
