Hello again...
 

So I’m starting to fit the Airtex carpet kit. My old walls were so trashed I can’t use them as an example and I’m not sure which side of this tray the carpet is supposed to be on. I feel like it’s supposed to be behind this tray but there is a lot of stuff in the way along that path and the carpet and backing is too think to fit. 

For those who have done this, how did you do it?

Side note...just finished the shoulder seat belt install this morning!F61BE80D-63ED-4154-A1B5-8201BAEC1222.thumb.jpeg.9d8ae90e69f8dacd60b238e18099e02e.jpeg60549F1E-6277-4FE1-A38B-AC012EB89AAD.thumb.jpeg.a0ea81ff73afa083560e4fbb737dee0f.jpeg73DA8625-9BBC-4AED-B336-FF2262508FA9.thumb.jpeg.430f28d90524ff25f80be70713515b28.jpeg

I just put an Airtex carpet set in my J. The carpet panel goes between the metal piece and the seat rail. the metal piece adds stiffness at the bottom so the side panel doesn’t flex into the wing root.

I see. Just doesn’t look like there is much to hold it there and I was afraid it would interfere with the seat motion. Worked for you I guess. I’ll check it out again. Thanks

How are those panels held in?  No idea where mine are from, but there are a few screws holding the carpet securely to the side along there.

My experience.......yes, the screws you removed in order to remove the panels should be reinstalled to hold newly carpeted panel in place.

Yes again, place the lower edge of the panels outside the aluminum strips for support. After securing, the panels should not interfere with the seat movement.

My N# is only 26 higher than yours.  I too am about to undertake the interior of my bird so I'll be following your progress.  Good luck.

I have a question for the group.  In the first picture, what is the material that is adhered to the inside of the aluminum sheeting (behind the bundle of wires)?  Mine has it too but not all M20's have it anymore.  It seems to be a paper/cardboard material that is glued onto the sheet aluminum.  What's its purpose?  Can it be removed?

I believe it is insulation/sound deadening.  I'm not sure if that is stock.  I was guessing that at some point in the 80's the tubes were inspected for corrosion and the old insulation was scrapped and replaced with the latest technology, but if yours has it...maybe it is stock.  I think some people replace it with the latest stick on sound isolation tech.

I want to replace that paper/card material with a more modern sound isolation but I don't want to remove it until I figure out why its there/what it does.  I'm wondering if the fiberglass insulation that these planes had when new had a paper backing?  Somewhat like insulation for your home, one side of it is lined with brown construction paper.

Original insulation was akin to Rock-wool... looks similar to fiberglass, but isn’t...

It was responsible for helping tubes rust away... it was really able to hold moisture against the tubes...

The fabric side walls are really cool... most didn’t get to the new millennium...

Beneath the 60s fabric was a touch of foam padding(?)... over cardboard...

If you have all of the original cardboard... that would be amazing... that would be a sign that somebody didn’t let any moisture or fuel leak into the cabin... ever.

Or your plane has been living in a museum...   :)

My M20C lost it original fabric and foam and cardboard right around y2k... is was water stained, fuel stained, and screamed un-loved...

The biggest challenge, the windows weren’t sealed very well in the 60s... water entry was a real possibility each time it rained... Cabin covers didn’t become popular for planes in general until the 90s at least...

Get rid of any fiber looking insulation... lots of good closed cell foam aviation products available...

PP thoughts only, not a mechanic...

Best regards,

The nasty vinyl stuff I removed was vinyl, foam, and basically brown card stock. OEM?  Can’t be right?

Great pics, Nuke!
 

Cardboard and foam... original...

a lightweight airy fabric on top... easy to ruin... was original...

Somebody may have ‘upgraded’ to a vinyl material...

Or the factory went vinyl over time...

This is typical automotive interior stuff that only needed to last five years...

Sort of standards of the day in the 60s...

Mon N # est seulement 26 plus élevé que le vôtre. Moi aussi je suis sur le point d'entreprendre l'intérieur de mon oiseau donc je suivrai vos progrès. Bonne chance.

J'ai une question pour le groupe. Sur la première photo, quel est le matériau qui adhère à l'intérieur de la feuille d'aluminium (derrière le faisceau de fils)? Le mien l'a aussi mais tous les M20 ne l'ont plus. Il semble s'agir d'un matériau papier / carton collé sur la feuille d'aluminium. Quel est son but? Peut-il être supprimé?

Are you talking about those self-adhesive parts ?

Ah ok ! Sorry. This is a closed-cell polyurethane foam insulation-soundproofing (the same foam is used on the roof pavilion to support the sky in the fabrics)... Thickness 3/8 I think. These foams are available in rolls with sometimes an adhesive side. We use this type of foam at home, in class M1 (fireproof). I don't think it's the original assembly, but it's better than rock wool on kraft paper, glued to diluted neoprene glue (contact glue) and applied by gun or brush depending on the place.
