Hi Mike

Interesting and hence worth turning into conversation pieces. However the resultant time keeping is going to be very variable due. The work on escapements in the past is concerned with minimising or countering the effects of the working atmosphere in the way of dirt - corrosion - oil migration - oil oxidation. The wire escapement has similar issues with constant impulse to the pendulum which might imply that the base rolling line in your novel rodless pendulum should curve at the extremity of the travel so that it will disipate energy and hence stand being over driven.

Like the solidworks stuff - gives a very clear idea of how your escapements would perform.

This animation of the Arnfield escapement may give you some inspiration on how to provide constant impulse.

I suspect your nice work on the rodless pendulum is a conversation time piece not a regulator.
