I am looking to get some ideas of doing the left exhaust hangar mount. 

Does anyone have any photos of what they did? It seems a bit rube 

goldberg as there is a lot of interference points: the air cooler, the 

heat scat, tubes, etc. Any ideas would be great!



thanks

Thanks Robin.. That firewall forward is quite heaviliy modified from the 

stock setup, though. However, maybe i can steal a couple ideas from your 

setup.

I am assuming you are using the stock Vetterman....  that being said, I tossed the original brackets aside, and built my own out of stainless.  (I know several of you out there, just said, "of course he did").... It seemed to me that to be properly positioned the bracket needed to be bent, and the original bracket had lot's of mounting holes in it, which would have made it even weaker.  The attached pics should help.  Just zoom in on the first one to the actual bracket.  I made a couple of extra if you're interested. 

 100+ hours and no problems whatsoever.

I did it per the (scant) plans with the Vetterman exhaust.  I'm not a 
	


metal work/rigging type guy but it worked much better than it looked.  I 

was able to position everything  exactly as needed.  Worked quite well 

for this builder.

Using Vans metal tubing with rubber hose stock and dual clamps, I found that with time the clamps will allow the hose to slide down from the initial position.  The exhaust stack made contact with the fiberglass lower cowl.  

   

A beading tool allowed a quick ridge to be formed on the metal tube stock to capture the hose and clamp.  Looks like it will be a longer term fix.  

   

Some of you might find the similar change over time.

John, I roughed mine up with very coarse sand paper and it has not slipped in 650 hours.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Don,

  

 Do you remember where you found those red rubber washers that you used to  isolate the upper cable end from the bracket? Are they heat resistant or  anything special?

  

 Thank you,

  

 Roger

All during my build I wandered through my brothers shop and confiscated everything that I thought that I might be able to use during my build.  Among those were several sections of rubber left over from military/govt projects from the past.  Then I just make the washers out of that.  I can send you some if you'd like.... got lots.... sent some to Pascal last week.

For those that want to purchase Vans exhaust hanger kit.  I could pick it up at Van's, cut the tube into two pieces and provide two new beads at no cost.  The rubber hoses "work harden" over time, they swell and will slip off many prepared tubes.  YMMV.  The errant aircraft was a ten year old RV-6A built by a repeat offender, tech advisor and RV-10 builder.  Five separate fixed brackets would all break after a year or two(Stainless, Titanium, Aluminum… it just did not matter), where attached at the lower side of the right rear cylinder.  Vans advice was their flex hose (properly installed) route.  First year of installation and the hose slipped right off without proper prep.  Scott's method should slow the slipping process.  The unfortunate thing was the hot exhaust stack resting on the resin of the fiberglass lower cowl once the connection was freed.  

   

Pictures of Deems shows a system which should work just as well.    

   

Those with auto or motorcycle experience will know what is meant by a "bead installed" on the hose end of the tubing prior to clamping.  

   

The nice thing about Experimental is that everything is Okay cause you the builder set the standard.  The bad thing about certificated aircraft is someone defines a single method of compliance and others become liable.

Thanks Robin. I think this new setup might work well. Just mocked up now 

and not final fitted yet. Robin used a clamp around the mount against 

the firewall, which i had not considered. It actually looks like the 

better spot for a clamp. There is much more clearance you can easily see 

in the pics. It is a tight fit for the clamp but you can see the wedge 

used to give a bit of room.



before:

http://picasaweb.google.com/lh/photo/A9mT9HXyj7yKkkz3NrP4kQ?authkey=Gv1sRgCI7088GZlYCc2AE&feat=directlink



after:

http://picasaweb.google.com/lh/photo/-ictyfdhx9QfrQrIAIFkvQ?authkey=Gv1sRgCI7088GZlYCc2AE&feat=directlink



The right side is much easier. The left side is more crowded because the 

2 4 6 cylinders push the exhaust further aft. However, too far aft, then 

the oil cooler starts interfering. The sweet spot is definitely smaller 

on the left side.
