Thanks for the clarification. Nice graphic Bill. You learn something new every day. I must admit I've never thought about this, but it might have been something you figure out at the time. However it does appear that many people haven't.

Agreed, that's a helpful graphic for those of us not-yet FWF. Thanks, Bill.

[and nice to see you "owning" that title Paul gave you in another thread; it's like you were "tapped" with a knighthood! I'm seriously jealous.]

Flash light
 
How many of you are looking at the baffles with the cowling installed (can you? as I don't have the benefit of an RV nearby) A couple of properly places "snips" cured a hot cylinder on a lycoming/maule installation. You can actually rely on air pressure to aid in a "shingle" overlap to seal well. Having a few pieces overlap at the aft end seal better than one waved piece.

When I had my Bonanza, annuals had to be signed off by an IA, not just an A&P.

Sample of perfect baffle seals
 
Would anyone like to show us a really good sample of his RV9/RV7 baffle seals? My ones are worn out (I bought a flying RV9 ) and I would like to redo them ... but I haven't got any picture how.

Does anyone would show us a photo how they should look like especially the difficult spots at the front of the cowling and the air inlets? Thank you so much for your help and your advice. :cool:

Here is a diagram I found on the net:

And the first few times you fly with your plane, you'll be peeking inside through all sorts of convoluted means to make sure the baffle material has fallen the correct way.

Nose & Air inlets
 
Thanks Bob,
unfortunately this drawing doesn't show the lining of the baffle seals around nose and both sides of the air inlets, thats why I am asking again, sorry. Any help with a picture of your RV7 / 9 baffle seals ?
Thanks Pit

Any chance you can post those for the rest of us?
