line folds

These folds produce raised lines  in flat sheet of metal that look like chased or constructed lines.
they may run across an entire surface or be restricted to a shorter strip. fold the metal where the line will be placed and mallet  the crease flat ,as figure A. the tighter the fold edge ,the sharper the resulting line will be. Anneal and open the  form with your fingers, then put it in roll mill to it flat.

Rueger fold

This is an extended forged line fold with a varying proportion of leg-to- fold edge. make a long line fold and mallet it tight. cut the metal on a curving line that angles away from the fold. this varying leg length creates a helix that results when the fold is hammered. the shorter the leg the, the greater the curvature.

Plunkett fold
