There is so much about aviation which is overlooked and
taken for granted. So endless is the
list of items required to make flight happen, skills, techniques, and knowledge bases, even
those in love with flying often have no idea how much went into the most common
and simple parts. B ecause
of this, aviators also tend to be overly critical of the price that comes with
the passion.
Sure, a Ford starter that can be bought at NAPA
for $125 should never cost $750 because it’s being sold into the realm of
aviation. B ut
what about the items which are mostly unique to aviation? How about the spinner?

How many pilots have lamented the cost of a spinner when theirs
went beyond repair? “That simple little
piece of aluminum can’t cost that much”, is sure to have been spoken a thousand times by aviators shocked to learn theirs was dented by hangar rash or found cracked during annual. There’s nothing to it, right?
There is more than one way to make a spinner but they all require a ton of work. |
If you’ve never seen a spinner made, here’s a great ten minute video to watch. Keep in
mind the prep is not included and the video is edited to keep it short enough
to watch. No crafting of the spinner
blank is shown, nor is the construction of the die used to make uniform parts. The cutouts for the propeller blades are not demonstrated and even the holes that must be
drilled for attachment to the back plate are not created. And for that matter, the back plate
construction is also absent. All that is displayed is the basic shaping.
