QUICK SWITCH
BY J.D. WOODS, EAA 89812
HERE IS A TOOL that anyone building a metal aircraft will find valuable. Many times it is
necessary to use an air drill followed by a rivet
gun. One example would be chasing a hole so the
rivet will fit.
It is a waste of time to have to switch hoses
and perhaps reset the regulator to accomplish
this simple task. By using an aluminum block
drilled and tapped to accept one air inlet and two
air outlets, you can easily switch tools. The first
outlet is at line pressure for the drill, while the
second is regulated for the rivet gun. Air enters at
line pressure and is directed to a quick connect
fitting used to power the drill. Line pressure is
also directed to the regulator so pressure can be
reduced for the rivet gun. The gauge allows the
pressure for the gun to be known.
