I take it your making these bracelets out of flat stock that is semi
finished into half round in the cross section. The best way to form
this stuff without getting to expensive is;
No.1 Get a stepped bracelet mandrel and put in a vice. Oval or round
mandrel that comes to nearest to the final shape.
No.2 Mark the centre point of the bracelet and bend from the centre
to the ends. ( Do not use hammers or pliers. They leave tool marks.)
Hand bend if you can.
If you must use tools, make them from wood. Wood is soft and will
not mark the surface. A piece of hard wood 6 x 3 x 1 inches with a
couple of 1 inch dowels almost side by side drilled and inserted
into the hard wood, works well. This is wood hand jig.
If your still having problems with symmetry, mark the centre and
mark the bracelet about every half inch and label the marks
This will give you something to compare, so the sides are even. If
you have a drawing program on the computer, make a pattern. Hope
