Lesson 8: Scoring and Bending

Lesson 8: 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.
