I just recently made a circle cutting jig for my router. I was looking through Rockler's site and I saw that theirs says it will cut an Ellipse along with a circle. I read the instructions that they posted for making an ellipse, but it doesn't make any sense to me.
Their Instructions: http://images.rockler.com/tech/RTD10000285AA.pdf
If anyone can explain how this works, it would be appreciated.
It would be great if I could use the jig that I made to cut both circles and ellipses.

Designed for use with just about any plunge router, the Rockler Ellipse/Circle Router Jig lets you cut circles and ellipse shapes over a wide range of dimensions and proportions. Set up takes only a couple of minutes and is virtually math-free. Using the jig is just as easy. As you move the router through the cut, the jig's sliding dovetail mechanism keeps the router precisely on the cut line.
Maximum length for major axis is 52".
Maximum difference between minor and major axes is 8".
Includes jig arm, jig base, two dovetail keys, and two locking pivots.
Single pivot can be locked to make circles up to 52" diameter.
Pre-drilled for Porter-Cable 690/890 routers or routers with 6" base footprints.
Made from 1/4" thick phenolic for durability.
