The Chief Delphi Robots have been on more diets than Oprah!

At this point we estimate that we are 3 lbs over. Working on it.

At the present, weight is only one of several show stoppers that we are fighting.

One involves a simple matter of conversion between the metric method of defining gear teeth (module = millimeters of diameter per tooth) and the English method (Diametral Pitch = Number of teeth per inch of diameter).

What I WANTED was a 24 DP gear with 37teeth. What I had made was a 0.9449 module gear (24/25.4). What I SHOULD have had made was a 1.0583 module gear (25.4/24).

As the folks from the NASA mars mission can tell you, conversions between English and metric can cause a lot of grief.

Right now, I wish weight were our only problem. But it is not.

Joe J.
