re: OB Woodworkers Help: Claw Miter? (Fishfighter this means you)

Claw Miter joint might be just what they call it there.

But you could honestly run with any of those other miter joints that some have posted for routers.

I don't think you'll be able to run that through a molder, since it runs boards through similar to a planer and the knives cut on the face grain.

This will have to probably have to be done with two fully-custom shaper bits. You would definitely want a shaper for this process. 16 footers continuously through will require some horses and a larger bit to not burn up the carbides so fast.

You could probably inquire with Freud, Amana or possibly Whiteside, although I think Whiteside does just router bits not shapers.
