How to make a oval template?

[Dale Thompson]

That is what I told that spanish dude with the three boats... but we think he fell off the edge of the world.

Dev,
He can't say that I didn't WARN him. What of waste of three boats and their crews - right into the jaws of the sea monster - unless he went off the edge first!

Word of caution here. The use of two opposing parabolas will get you into trouble. Dale is right. That is not the usual formula for an ellipse... rather, its something I used years ago doing some layout. Dont even wish to go there on a woodworking forum.

A circle is a special case of ellipse in which both centers are conincidental.

But who needs to remember all these goofy equations when you can just setup the micro fence. Using a micro fence makes this task brain dead and what the micro fence does not kill in terms of brain cells, jack daniels does the rest.
