Fun Stuff: Number of rivets in all kits.

I counted the rivets called out for in the FWF plans and updated the chart on the lower right of the blog's main page.  Here is just the final RV-14A rivet count.

Empennage 4,446
Wings 8,276
Fuselage 6,250
Finish 1,265
FWF 234
Options 20

Total: 20,499

The tail dragger would be very, very close to this number (in fact, same for wings).

Want to wrap your brain around the mindlessness of the tasks involved in building a kit plane?  Consider that each of those rivets represents at least one hole (sometimes many more when parts are stacked) and each of those holes gets at least two deburring tasks and sometimes match/final drilling and/or countersinking/dimpling and/or sealant application too.  You can then calculate an upper-bound on the number of tasks per hole using some worst-case assumptions:  Just 6x the number of rivets to get a grasp on the number of tasks involved with the holes.
