The problem with the VQ P-38 wing and the fowler flaps is
the connection of the linkage from that main body to the outboard flap
mechanism. It is a small ball connector that my large fingers cannot
reach, and I worry about breaking the linkage with a needle nose pliers.
With a little imagination I think I have found the solution.

Take brass tubing (I believe a stronger
steel thin wall tubing would be better, but this works for now) of 11/32”
and cut out a slot .115” tall using a dermal tool half way through the
tubing. The bottom must have an opening .150” to go around the ball joint.
A very slight radius in the center of the opening toward the long end of
the tool makes fitting over the ball joint easier. |

Get a wooden dowel 3/8 inch. Chuck up in
drill. Get small coarse sandpaper and hold the dowel with the drill
turning to reduce the dowel to .300” to slide into the brass tubing. Drill
1/16” hole into the end of the dowel. (Must drill or dowel will split) and
screw in an Allen screw with wood threads into the center. This is the
“Punch” for the puller. |

|
Here is shown the dowel inserted into the
tubing. The jaws go under the ball joint to hold it and the dowel is
pushed down to pull the ball joint. |

|
|
Here is the fowler flap linkage inside the outboard wings
and the hard to reach ball joint. |

|
|
Slide the tool, with the dowel retracted
over the ball joint, push down on the dowel and the jaws hold the outer
part of the ball joint and the Allen headed bolt pushes the ball joint
apart without stressing the arm or joint. |
|
|
Joint removed. |

|
|
Now you can modify the other end of the
tool with an opening of .520” and jaws as similarly described. Modify the
other end of the dowel with a small concave hole, and the puller becomes
the ball joint installer.
