 Posted on Tue Aug 14, 2012 8:23 pm Link to Post: Hello! Maybe you should read the article about the AR. It explains the relationship of wire diameter and inner diameter of the ring. There is also a nice picture with the byzantine weave (with different ring sizes). BTW you'll get a nice tight weave with an AR of 3.5.

3 mm wire?!? That's around 8-9 gauge, and it is very, very thick for byzantine.

We can use this example, anyway, with my Excel calculator. I plugged in 3 mm for the gauge and 3.7 for the AR (which looks pretty nice). Based on these specs, you will need rings with an inner diameter of 11.1 mm. Huge!

I often use 20 gauge wire (0.81 mm diameter wire) to make rings with a 3.0 mm inner diameter. AR = 3 / 0.81 = 3.7

You can view / download my Excel calculator on my chainmaille resources page here http://chainofbeauty.wordpress.com/chainmaille-resources/
