Nissan Armada 2025-2026 Service and Repair Manual: Scribing Chisels
Chisels are generally used to cut sheet metal.
They are also used in body repair work. There are numerous types of chisels. This section, however, describes scribing chisels used exclusively for bending sheet metal or for shaping panel press lines.
This type of chisel must have a smoothly rounded edge as shown in the figure. If the edge is sharp, the body panel will be nicked.
HOW TO USE SCRIBING CHISELS
(a) For bending sheet metal
First scribe a line on the sheet metal.
Place thick paper or cardboard under the sheet metal.
Place the scribing chisel on the line and hammer it.
Place the sheet metal on a flat, angled surface scribed-side down, and bend the sheet metal with a wooden hammer.
Using a hammer and the scribing chisel, neatly bend the sheet metal squarely. Do not bend all at once.
Bend the sheet metal gradually by gently hammering against the chisel head.
(b) Shaping the press line
If the dent in the press line is smaller than the width of the chisel, apply the chisel to the center of the dent. Hammer to flatten. Hammer gently so that the dent can be removed gradually.
If the dent is larger than the width of the chisel, do not strike the dent in the center. Apply the chisel at the edges of the dent.
