Working
With Sheet Metal Tutorial
Page Two: Filing, Sanding, Buffing, & Finishing
Many of the tools utilized in this tutorial can be purchased
in the Warehouse Store. |
| |
Filing |
| |
| Use a flat file to smooth the outside edges of the metal.
If you are filing concave curves, use the rounded side of a half-round
file to smooth the curve. Secure the metal into one of the small
slots in the V section of the bench pin; these fine
slots are created when as you saw and eventually you will have
a lot of them. Using pressure on the file, file in a straight,
forward direction. Resist the temptation to saw back and forth
with the file. The teeth will only cut in the forward direction;
you may shorten the life of your file by going against the grain. |

Use a half-round needle file to smooth the inside curve. |

Sanding |
| |
| Locate the deepest scratch in your sheet metal and sand across
the scratch with the appropriate wet-dry sand paper or a sanding
sponge. You might start with #220 grit (coarse) and progressively
work down to #400, then #600 (fine). (After some experience you
will be able to determine what sand paper you need to start with).
After sanding against the scratch, sand in the same direction
as the scratch with the same grit. The last pass with a particular
grit should be against the scratch. When you start with a new
grit, sand in the same direction as the scratch. You are finished
when the prior sanding marks have been removed and you can no
longer see any scratches. |

Buffing |
| |
Buff with White Diamond Compound with a small stitched cotton
buff on your flex shaft. |

Remember your safety glasses and wear a particulate mask for
this operation. Keep your buff moving so you dont wear
a groove into the metal.

These metal working skills will bring you enjoyment and add
style to your wire work. Dont forget, it takes time and
practice to become proficient with these new tools and methods.
Dont hesitate to enroll in a class or ask for help from
an experienced metalsmith if it is needed. And speaking of classes,
I am especially grateful to Deb Jemmott who taught me these fabrication
skills.
Creating texture is my favorite design element and there are
many options in this area. Please look for a tutorial in the
future on texturing methods. |
