i didn't have to rotate my positive screw, but they positive post has holes in it so it shouldn't be a problem getting your wire through from each side
here's how mine is currently set up
i've tried it with vertical and horizontal coils, and they both seem pretty good
i recommend using 1 continuous wick so the wells are drained evenly
using drill bits to position the coils like player one did helps a lot when screwing the posts down and maintaining your coil's shape and position
