Because I was thinking that for that kind of money, I can buy a
special-purpose endmill that will mill the 70-degree (included angle)
groove to fit the bedway V-rail. If as-milled isn't quite precise
enough, I can always scrape it into perfection.

Any reason you can't use a regular endmill and tip the part 35 degrees
to cut the angle?

With a 70 degree included angle, and a normal 90 degrees between
the tip and the side of the mill?

Granted -- 70 degrees seems a lot narrower than on my Clausing
lathe -- a 12x24" model 5418/
