About

Chainmail Jack is a set of guides about making chainmail: weaves, wire gauge, ring sizes, tools and projects. It used to sell supplies. It no longer does. It is now a reference site, and it pays for itself through affiliate links and advertising.

The guides give numbers that can be checked. Gauge diameters come from the standard SWG and AWG tables, aspect ratio is plain division, and ranges are labelled as approximate when they depend on wire and technique. If something here is wrong, say so and it will be fixed.

What is on the site

Guides, weave comparisons, buying advice and two calculators.
