An ellipse is an oval shape with no regular radius

It is set up along 2 axis

The “X” axis is always the longest one.

The “Y” axis is always the shortest one.

Step 1. Mark out the “X” axis.

Step 2. Find the centre of the X axis.

Step 3. Mark in the “Y” axis.

Step 5. Move the compass to the Y point and mark of the distance along the X axis

Step 7. Tie a piece of string, (builders line is best) to the nail at F1.

Too tight and it will pull the nails out

Too loose and the ellipse will be the too big

Now you have created the perfect ellipse.

You can use a band saw or jig saw to cut the shape clean up the edges with a spoke shave, compass plane or disc sander and make a router template.
