Hi
Now I have been flying 750 hrs. with my exhaust end pipe clamped to the mufler
with two ugly big half-rusty clamps
Any reason why I should not TIG-weld that end pipe direct on the mufler?
No problem getting the under cowling on and of with the system assembled.

Hello Rowland,
Quite probably way past its sell-by date but, according to Karen at Europa, the
TW spring is SAE 6150 steel alloy, hardened & tempered to Rockwell C42-44. Later
ones also come zinc chromate primed, so the implication is to paint it.
I would prefer to leave mine bare metal in colour to match the main gear leg, so
I enquired about plating with a specialist (Precision Aircraft in Reading) and
they advised:
"I have attached a photo of a cad finish so you can see what colour your part would
look like when plated, cadmium is a white colour but is dipped in the olive
drab passivation solution after plating and de-embrittlement. Your part would
require stress relieving prior to cadmium plating 190-230C for a minimum of
4 hours. After plating your part would require de-embrittlement which would be
the same times and temperature as the stress relieve."
I don't much care for the resulting colour, so I may be forced to paint mine white
- it is far enough away from the main leg not to jar on the eye and Dave J's
doesn't look too bad after 14 years...
NB the attached picture is NOT what a TW spring looks like after cad plating!

I have in my possession an original tail-wheel fork in mint condition, powder-coated
white, never used. Who's interested?

Hi Gert,
I had a problem with the tail pipe coming loose no matter how tight I made
the clamp. I have a TIG welder but I didn't want to weld on the aircraft due
to the high frequency voltage that is part of the welding current. My
concern was that it could damage my avionics.
I solved the problem by drilling a small hole in the pipe under where the
camp goes and putting a stainless steel pin. The pin had flange on it to
keep it in place.
If you do want to weld it my recommendation would be to remove the muffler,
which is a bit of pain to do.
Hope this helps - Paul

Paul - I also decided to paint it - etch-primer + Halfords Appliance Gloss White.
Its not quite as robust as plating or other chemical treatments, but its cheap
and simple!

Hi Gert
My 914 exhaust is made out of 309 Stainless Steel. I plan on welding on a Stainless
Steel Bung to mount an O2 sensor. I purchased some 308L Stainless Rod. I
think it was from either McMaster, ACS or Wicks.
I verified that 308L is OK to use on 3098.
Good Luck.
Ron P.

Gert=2C
You are a patient man.
I have done it many ways. The Trigear is hard to cowl up without the clamp
. The mono is easier.
I welded mine on once I was comfortable with the length and angle. I don't
like to have loose stuff. My tailpipe is short=2C so I have exhaust stain
s.
If you like a long pipe that is removable=2C the best way to assure your pi
pe doesn't fall into a schoolyard=2C is to pin it. We use an 1/8" hole thr
ough the overlap area where the clamp rests. We tack weld a pin to the cla
mp like on a Continental. One can also use a screw and clamp over it. We
use a small head screw and dimple the wide band clamp for the screw head.
Then we weld a loop ( a U of welding rod ) on the tail pipe and muffler stu
b. Then safety wire the loops. Its like belts and suspenders=2C but we ar
e annal.
