Vertical Stabilizer jigging

As I’ve said, my empennage kit is 15 years old.  So, I don’t have the benefit of match-hole technology that the newer kits have.  The skin on the vertical stab is pre-punched.  But, the ribs and forward spar are not.  So, the skin has to be drilled onto the spars and ribs.  I chose to follow the method demonstrated by George Orndorff in his video series on building RV 6/7/8 kits.


This is how it looks as of this morning.


Here, the vertical stab is in the jig.  And, I’m getting the skeleton lined up by using the dimensions called out in the drawings and by using my Mk-I, Mod-0 eyeballs to spot the sharpie lines I drew on the ribs and forward spar.


While trying to puzzle out exactly the best way to flute a rib that was slightly bowed, I stumbled upon the discovery that, in good light, the fluting locations are reflected onto the flanges of the part if I match it up with the full-size drawing.  For the actual fluting, I followed the method shown in the EAA “hints for homebuilders” video at .

  1. I don’t write a bunch of remarks, however i did a
    few searching and wound up here Vertical Stabilizer jigging | Ken’s RV-8.
    And I actually do have 2 questions for you if it’s allright.

    Could it be simply me or does it seem like some of the remarks come across
    like they are left by brain dead folks?
    😛 And, if you are posting on other places, I would like to keep up
    with anything new you have to post. Could you make a list of
    all of your communal sites like your twitter feed, Facebook page or linkedin profile?

      I don’t do FB or Twitter. THis is pretty much it. I’m on hold right now because of a family illness. Hope to be getting back into the shop again soon.
