I would love to see a picture of this exhaust system Jareds..since the
note below mentions ball joints. Something I am considering installing.

I have found that if your exhaust pipe is cut too short you can get
fumes especially on climb out, but you can usually see exhaust soot on
the plane if that is happening. The ball joints seems to have some
leakage signs on the pipe, but you should no be able to detect any with
smell or with a detector. If you post a picture of your system someone
might see something that will help you out. Exhaust fumes are nothing to
mess with.

--> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net>
I just started to attach my flap hinge brackets to the wing, and
noticed that the called for 1/8 x 1/4 alum pop rivets (#95007) have
aluminum mandrels. They seem awfully easy to "pop"....that is, they
don't seem very strong. In checking the Aircraft Spruce catalog, there
are no alum rivets with alum mandrels available. This makes me think
that the alum rivet with steel mandrels might have superseded the
alum/alum rivets. My question is what is the group's feelings regarding
this matter....quit using the alum/alum rivets and get alum rivets with
steel mandrels, or are the original rivets strong enough? I don't think
the "popped" mandrel really adds any strength to the rivet, but maybe
it does.

I have asked this before and did not receive a response so I will try again. What
do most people suggest for power settings ( i.e. - throttle and prop ) for
a 914- 80 HP for cruise?
I have a CAP so I can set the prop most anywhere.
Thanks

Lynn,
I think the design of the bracket to rib attachment is plenty strong
with the aluminum rivets. With 16 rivets holding each bracket to its
rib, they are not the weakest link in my opinion. If you tried to pull
a bracket off a rib I think the wood would fail before you could break a
rivet.

Another "possible" hazard of using hard rivets like stainless is, they might
tend to pull through the thin alum backing and/or crush the wood. I too
think the provided alum rivets are strong enough.

Yeah, you're probably right, Tom....I guess these rivets would be in
shear, primarily, and 16 of 'em should hold, but it just struck me to
ask. They probably aren't in tension, due to the holding power of the
two bolts, but I'm not an engineer, so who's to say whether they are
stronger in shear as oppose to tension? Maybe I'm just getting paranoid.

Hi Lynn.
IMHO steel-aluminum rivets are prone to galvanic corrosion because of the different
electrical potentials in dissimilar metals. Hence the specification of all
aluminum rivets. You can get any kind of pop rivet from Barnhill Bolt Co. (barnhillbolt.com).
I don't think the relative difference in strength (if any) is
an issue but you can check the specs on Barnhill's site.

Lynn,
Actually, the popped mandrel does add shear strength if the rivet is
designed to retain the mandrel. I do agree with Tom, you'd tear the rib up
pretty bad before you could shear the rivets...
Regards,
Ted

Don,
Kinda know the feeling, was being directed off the runway at Oshkosh and hit
a large rock with the right tire, the tail came off the ground but
fortunately the prop never hit. The guy said it was OK to proceed but I shut
it down and walked it through the transition.

I assume that you are not working on a 7. The 7 uses a different bracket
and different attach inside the wing. On that setup you need SS, but you
are pulling against a steal cup type bracket that sandwich the wood of
the rib and only attaches from the top. Skystar builds in a healthy
safety margin and would go with what they say. If you have any question
on safety of flight items a call to the factory would be in order.
