=0A=0A=0A =0AJimmy, =0ASome time ago, the factory went to-another exhaust
manufacturer CKT =0AAero engineering and they did a good job of remanufact
uring our exhaust with =0Athicker, better stainless steel, better muffler s
upports-and less stress on =0Athe mandrel bends of the pipes.- CKT also
makes systems for most of the =0ARotax powered kits in Europe.- Too bad
we all had the older exhaust sold to =0Aus before which cracked at the exha
ust, pipes and everywhere for mostly harmonic =0Areasons .- The only prob
lem with the CKT exhaust was the springs, which =0Awere standard motorcycle
carbon steel type, now he makes a stainless steel =0Aspring to try to get
better longevity.- CKT stands behind their products =0Aand has taken care
of me. =0A=0ANote:- In certified aircraft we put RTV or high temp red si
licone on =0Athe springs to reduce vibration harmonics.- I run a piece of
safety wire =0Athrough the spring and pull it up loosely.- This keeps an
y fatigued springs =0Afrom becoming FOD. =0A=0ASome History: =0AThe 912S ha
rmonics cause the exhaust to move laterally a bit and that will =0Afatigue
crack in the bend of the exhaust of any system and if the springs were =0Am
ade tighter, the muffler supports cracked.- We all know how bad the =0Aal
uminum heat shield was.- Also the 914 had some real problems but over =0A
time, metal bends went to welded seams and we have been trouble free.- Th
e =0Aoriginal 912 exhaust was kept as light as possible, but the vibration
and =0Aharmonics caused fatigue cracks at very low time.- My first experi
ence was =0Awith Ira Rampil's exhaust which cracked in about 4 places.- C
hris at CKT =0Areplaced-the old-exhaust with his and we went through so
me teething =0Apains with it but not too bad except for spring failures on
the right side of =0Athe engine.-Contact Europa for the new-exhaust sys
tem and clear up =0Ayour problems, but expect it to cost about $1000 US or
about -660 UK =0APounds.- =0A=0ABud =0A=0A=0A----- Original Message --

ay,=0A>>>I am =0A having trouble with the gusset plates. I used the 12
ply supplied and =0A shaped it accordingly, except I have about a 5 m

hat. So, I bonded on the ply and =0A then layed up the 4 plies of BID,
which in essence thickens the ply by 8 =0A plies. So, now that its al
l done I have a 2-3 mm gap +/- and the gusset =0A plates do not sit pa
rallel. For the other side I lightly clamped the =0A plates together a
s the BID cured, in situ, and they were covered in =0A Canauba Wax for
a release agent. So, that side is OK, but the first side I =0A have a
problem I am hoping I can use Redux and Flox to pack out both the =0A
gap between rod and ply, and also to create a flat bed for the gusset =0A
plates. I am wondering this would be considered an acceptable way to f
