REMOVING SPOT WELDS
The actual side panel removal requires the drilling out of
spot welds which attach the side panel to other panels of the
cab. Sheet metal drill bits should be used. These are drill
bits, the ends of which have been ground for this special
purpose. An example of a sheet metal drill bit as compared to
a regular drill bit is shown in Fig. 37. When spot welds have
been removed, a pneumatic chisel is then used to open
seams which have been clinched together.
