I've been trying to build a working clock tower for the server I play on and have come into a problem. I can get the whole clock to move as it should but every so often the pistons will glitch out on a face and stop working. I think this happens because all the pistons are pushing at the same time. So now I'm trying to separate the currents leading to the pistons. I've tinkered quite a bit with it on creative and have yet to find a good way to do it without making the original design bigger and showing the wiring. I would really love some help with it.
