the surface being smoothed. With the tool turning at
maximum rpm, you then press it in towards the surface,
maintaining the 90-degree angle. The pressure feet will
then be compressed until they bottom out. At this time,
assuming the rivet-head shaver is adjusted correctly, the
rivet head will be shaved aerodynamically smooth.
Pneumatic Riveters
Rivet guns vary in size and shape and have a
variety of handles and grips. Nearly all riveting
is done with pneumatic riveters. The pneumatic
riveting guns operate on compressed air supplied
from a compressor or storage tank. Normally,
rivet guns are equipped with an air regulator on the
handle to control the amount of air entering the gun.
