Cheapass dovetail cutting - fly cutting style
Chrispy:
There was an article on this very thing several years ago in one of the US HSM magazines. It was for cutting a 60 degree dovetail with a flycutter. It talked about how to step the cut over and down to follow the 60 degree slope. I guess what you would call a type of manual CNC. I will see if I can find it and post what issue it was in.

Knocked this up a few year ago: (see pic)
Worked quite well with light cuts

Problem there Todd its got a load of radius on the tip.
Many European sorry German dovetails are not that deep some are only 1.8mm. Very few go deeper than 2.4mm.
So by using a rad on cutter there has to be clearance on the opposite fitment ie mounts. Even then if there is clearance allowed at best it will reduce grab and holding zero.
There is no industry standard for cutting dovetails amongst producers, in fact take a certain Fen and theres three different sizes on same product.
Picatinny/Weaver has an undercut 45 with recess, top 45 degree angle and slots. Inundated making them and not worth while.
Not a good system any way limited on mount position every 10mm if cant slide scope through the rings.
