Dan, I was imagining some means of repeatably mounting the rotorule on the legs, have to be thought about.
Seems to me you'd use the sine formula for angles up to 45 degrees and cosine for 45 to 90 degrees. since the sine flattens out over 45 degrees and therefore gives much less resolution. but it may not matter. We'll mess with it when every one gets back from a spate of conferences and vacations <GRIN> Tom
