Armour Making Tutorial - How to roll the edges of armour
Rolling the edge to 90 degrees
In the previous step we formed about 1/4 inch of the egde of the armour outward to aproximately a 45 degree angle. Now use the same technique to bring just the outer 1/8th of the roll to 90 degrees.

As before, the trick is to work it slowly and evenly in multiple passes. This is all light work which does not require any heavy hammering.
