Large rings: 14swg 3/8" (4.8 AR), Small rings: 16swg 1/4" (4.0 AR)
19" long (without hardware)
Used about 97 large rings, and 66 small rings
* One of the reasons I don't use aluminum much for my personal jewelry is that even at 14swg, the rings tend to separate over time, and the aluminum gets pitted and dinged. I plan on remaking this with steel and titanium soon.
