I see many youtube videos where the time and/or strike weights are hanging from a compound pulley system. What's the advantage of doing this compared to not "compounding" at all? Logic dictates that the weights would need less vertical room if you compound the pulleys, but then you'd be required to use more weight. So, is the amount of "compounding" used in each tower clock installation a trade off between how much vertical height you have for the weights to move verses how much weight you can afford to buy? Thanks, Kevin.
