This picture shows a taper pin removal system with an additional tension spring.

This is a refinement over the first one. The hand lever is only 1/8" thick and is flush and contoured with the skin of the tail plane. In most cases it fits into the gap between the fairing and the tail plane. At most, one would have to file a bit of the fairing.

The reason for this design was to make it easy to remove the tight fitting pin in a straight line. This arrangement can generate up to 300 lbs of pull. It also saves my fingers , as they were building up bone spurs which started to hurt. The convenience is obvious. I do not know how I did without it.

"Plus it is a safety feature".
