Score And Fold Sheet Metal

This weakens the aluminium and creates a fracture line.

Score and fold sheet metal.

Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. Place it on the sheet metal to be bent i use masking tape to keep it in position then press it into the sheet to the desired depth using a planishing hammer. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. By perforating the metal at specific points much like how craftsmen score paper to create neater folds industrial origami claims that their procedure cuts down energy consumption.

Wells metalwork makes innovative use of foldforming and he has recently developed his own method of score folding sheet metal to create unique forms which touches on the cutting edge fields of curved origami and parametric modelling. Typically the user creates a deep score and then gently taps the material to encourage it to snap in half. Scores can also be created in things like sheet metal making it easier to fold the metal into shape. Silicon carbide separating discs are superb for scoring metal for bending particularly when the metal sheet is less than 4 or 5 cm across.

Therefore pvd sheet material is ideal for v grooving and folding as a cost effective alternative to brass bronze copper gold and iron. Next place the wood parallel and slightly behind the bending line. While i was originally taught to use discs for catch building which involves only straight lines i discovered that they are superb for curved line scoring. Watch the visual spread of the wire and keep it the same width in order to maintain an even depth of pressure.

To score using a wire begin by bending it to the desired shape of the score. His curved score folding technique has been recently recognised with two gold awards for technological innovation from the prestigious goldsmiths. Scoring tools can also be used to cut glass quartz marble and other minerals. Paul wells is a london based silversmith and jeweller renowned for his use of direct metalworking techniques.

If you want a sharp 90 bend tap along the crease with a mallet. Flip the sheet over and repeat. Finally bend the sheet up by hand to the angle desired. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.

Clamp the wood on top of the metal to the workbench. Place the fracture line over the edge of a table and bend the overhang slightly downwards.
