This metal box was fabricated with the jewelry techniques of scoring and bending. Copper, brass, or silver are the possible materials for this exercise. This project requires proficiency in soldering and scoring.

Separating disk on a flexible shaft

Rectangle & Triangle needle files

Saw blade & Saw frame

Soldering tools

Safety glasses

Metal sheets

Scribe

Combination square or protractor

All edges are bended perpendicularly and soldered. 

The amount of solder is well-controlled.

A piercing hole is presented for airflow.

1) draw marks on sheet metal to determine the boundaries of the cut out.

2) use a jeweler saw to cut out the faces of the box.

3) file the edges of the cut out. (Leave at least one hole or opening on at least one face of the box so the piece doesn't explode when soldering the edges).

4) place the cut out on the bench pin.

5) the separating disk should be on the mandrel.

6) with one hand hold down the piece on the bench pin. With the other hand, hold the flex shaft like a pen. 

7) at a high speed, make the first straight mark on the scribe mark. Score the metal with the separating disk. 

8) the finger holding the flex shaft should slide on the bench pin as you move the separating disk along the scribe mark.

9) using the corner edge of a triangle or rectangle needle file, file the score mark deeper. About 40 passes on each side.

10) bend each face 90 degrees. No need to anneal the metal before bending.
