I was already going to post a reply to Gerry's dovetail thread but did not want to highjack it with a sidetrack idea.

I would love to use Gerry's software but unfortunately my machine does not allow for overhang machining of a vertical piece.

But this got me thinking and I spent some CAD time this morning figuring out how to cut a dovetail joint practically with flat machining only. This does not require a dovetail bit but a 30-degree V-bit (like Amana In-Groove) and a small endmill, e.g. 1/8".

The one in the rendering and video below is "half-blind" but can be done as well fully blind or fully visible. The V-bit path for the one side of the joint would need something like VCarvePro to generate. I guess it would be difficult to do a similar custom program like Gerry's for that? Anyway, I will probably do an experiment sometimes.

I hope the pic and video give an idea what I mean.
