hi…i think it should work this way…if one rotation of the minute hand rotates in 1sec then it would take 12secs for the hour hand to do one rotation…so yur composition should be 12sec long at least and your minute hand should rotate 12 times for your hour hand to make one full rotation…maybe u can use an expression for this…give it a try…im not too sure coz im just working it out in my head…:)…cheers…merv
