   Rocker science doesn't seem to be an exact thing.  As you gain experience your rockers will improve.  A general rule of thumb will place the center of the rocker arc in front of and above the belly button of the user.  Rocker arcs are usually 36-48 inches in radius, shorter radius giving faster motion.  The tilt of the seat and the angle of the back to the seat will also affect the rockability.

   A good discussion was in the GALLERY a while back, if you can find it in the archives. 

   Rockers seem to work best if custom designed for the intended user.  Height and build of the user make a big difference.  If you've never built one, try to find some plans first (old Popular Mechanics Mag. come to mind).  Go to your local furniture store and try all the rockers they have in stock.  You'll be amazed at the differences between them.  Try to see what makes them better or not.  Some dealers are better then others letting you check out and measure up, wouldn't hurt to ask first.  Finally, do some trials first in cheap wood, even lumberyard spruce works.  This will give you a feel for what works before you blow a bunch of money and time on expensive wood and end up with a rocker that doesn't work.

   The first rocker I built was from a PM plan.  I didn't like the way it fit or rocked.  My family and others who tried it didn't like it.  I made some modifications and built a couple others, each different.  The first potential client I had liked the first rocker and ordered on like it in a nice wood.  Go figure.

   Rockers are a neat challenge.  Enjoy and good luck.
