1. How do you get the the paper counter weight on?? I have had no luck with it at all. After quite a while trying I just put the whole bar on top of the bottom edge of the paper and walked away.
2. How do you keep the paper from unrolling? I just switched to the expan system and while the roll itself doesn't turn, the paper unrolls partially by it's own weight. When I used a stand and bar, I just clamped it, but with the expan system I can't put a clamp inside the roll because the expan is in there.
