Demo: Scoring and Bending

Lesson: Scoring and Bending:

• Use your scribe and metal ruler (or steel square) to scribe a deep line for each corner seam.
• Use your triangle needle file and file down into the thickness of the metal at those points.
• When you have gotten 2/3 of the way though the metal, switch to your square needle file.
• Continue filing until you are almost all the way through the metal.
• You should be able to see a thin score line coming through the metal on the back.
• The closer you are to going through the metal, the sharper your corner will be.
• Bend the filed sides together.
• Solder all the seams.
• File the top and bottom edges flat.

Tips:

For a 90 degree (right angle bend, file a 90 degree groove.

For a 45 degree bend, file a 135 degree groove.

For a 135 degree bend, file a 45 degree groove.

The 180 degrees - the angle of your bend = angle you need to file the groove.

File from both edges- keeps the groove even.

Make sure not to file the edges more than the center of the metal.

Slow at first. Keep in the groove.

After soldering, you can bend the sheet on either side creating wave or scalloped shapes.
