Hi Vernon
I have searched through AC43-13 numerous times and can't find any torque
values. I'll take another look. The Standard Aircraft Handbook is on
my X-mas list.
I have been involved in balancing the rudder on my Cardinal so I will
consult our maintenance guy.
I hate to ask stupid questions, but will anyway. I have a rivet gauge
but didn't know how to use it. I get the feeling the little notches are
to gauge the rivet length that sticks out before you form the shop
head??
I wish I had asked that question before I riveted the rudder hinges onto
the spar.
Thx for your advise.
Regards, Rick

Hi Rick,
The torque ranges should be in the Standard Aircraft Handbook and
AC43-13 Aircraft Inspection, Repair and Alteration. If you don't have
copies of these they are very good and useful guides to have on hand.
As for rudder balancing, the plans are a little sparse. There are some
ranges in the finishing kit's instructions. But it only gives ranges. If
you know an A&P with a set of Cessna repair manuals threre is a section
in their manual that outlines how to build a balancing arm and jig. Also
discusses how to use it. Keep in mind that when you paint it will effect
the balance as well.
Through out the project you will find some rivets called out in the
plans are off in length. Just use your rivet gauge before driving if a
rivet is in question. As the project progresses you will find may times
by eyeing a rivet you will know if it is too ling or short. Then just
trade it out for the right length. As for the shop head size the two
reference books mentioned above should take about the min/max range for
rivet head size.
Congratulation on your project & enjoy the build,
Vern Smith (#324 Finishing?)

Hi all
A couple of questions
1) Where do I find torque values for the #6 structural screws that I
have used to attach the rudder stops to the lower rudder hinge?
2) I have just started the rudder and will be adding electric rudder
trim. Before I make some serious cuts in the rudder skin I want to do
some research into how the rudder is balanced, and thus make a few
calculations. Where are the instructions about how the rudder is
balanced? I only have the empanage kit home at present and I can't find
anything regarding balancing.
3) When I rivetted the lower rudder hinge onto the VS rear spar it
seems the rivets called out by Vans are a bit short. Did anyone else
run into this? Also it seems some rivets are also too long. If the
shop head is the proper diameter, does it matter if it's a little bit
thicker?
Sorry for the neophyte type questions but I gotta get this right.
Thx, Rick
