Hi i'm new to the forums, I've been working on a Quadruple piston extender laid horizontally. (I'm making a one block deep pool and want it to cover up). Anyways I've had no luck completing this, It would be easy if only i didn't need thirty of them side by side. If anyone knows if this has been done, PLEASE let me know, if it hasn't but you're willing to help I am more than open to receive it! I've gotten them to extend, but retraction is much more difficult to do in a one block wide space. I've attached pictures to show what I've built so far. Thanks for the help!
I managed to make a 1 Block Wide Quadruple Piston Extender on Ham5teak Creative Server after some time. Credits to you too. The way you placed the blocks beneath the 4 Pistons really helped. I will attach some images of the finished work. However, it might not very "clean" since I did it today.
