Ok.. Sons is over and I have done my experiments.. adding weight to the counterweight does not in fact slow this thing down... it makes the first arm reset too high so that a ball will fall straight though from the top path... lesson learned... Still a great design... 8 stars for you

Just built this most excellent element.... I'm guessing that if I add more weight to the counterweight, it would operate a bit slower... I'll let you know in a minute or 3... or after the Sons of Anarchy is over.... Good job
