The capping machine is therefore heavy and looks well built overall. All pivot points are free of tilt and play. The bad thing is that this tool is designed to create straight curves, but the alignment of the upper and lower jaws on the leading edge is misaligned. So if you fold down the crease will not line up as they are almost 3/16 inch offset. Since the jaws are molded the easiest way to fix them would be to simply sand/file the leading edges once the ruler is assembled, now I have to do that.
