[f-AA] 11AC window

[John Rodkey]

Anyone got a copy of drawings 3-469 and 3-470 ?

3 of my side windows are very scratched and beat up, and one broke in half recently.

For what it's worth, my existing copies of copies of copies of copies measure about nominally 12.75 tall by 13.5 wide for one set (the rear?), and 12.75 tall by 13.75 on the top and 13.5 on the bottom, more or less.

3 sets of qualifiers inserted intentionally.

What would be marvelous would be to have the actual dimensions, and the radiuses of the rounding on the rounded corners.  But i can get by with 'TLAR' engineering for the rounding if I had accurate width and length dimensions.

Why not take em out and use them as patterns?

What you really need are 3-572 and 3-573 which are the drawings of the Plastic windows.  3-469 and 3-470 are the drawings for the assembly frame and windows.  I'll be sending the plastic drawing soon as they are in fir shape. the frame drawings that you listed are in poor shape and will take a bit of time to clean and restore.

Hey John.  If they are the same as the sliding side windows on my 11AC, I just got some Plexiglas (or whatever it is) at Lowes.  They had a sheet the correct thickness and big enough to cut out two replacements.  Then as Rich suggested, I used the old to make patterns for the new.   I had first ordered the "correct replacement" from Wag Aero.  The material they used was too thick...and not cut totally correct....and much more expensive than Lowes.  The Lowes stuff is cheap enough that if you screw it up on first try, no biggie.     Oooops...I just noticed you said the rear windows.  Mine were front sliding.   However, principal still applies.    roger

I'm sorry John but those drawings are for the faster Champ planes. I'll look for the correct slower Chief drawings. <GRIN>

Here is the plastic piece of the 11 AC door rear window. I'll send the other half of the window after I have cleaned up.

Keep in mind that there are different grades of plexiglass.  I get all my plexiglass and acrylic from Delvies Plastics in Utah.  

Cut the plexiglass to shape with a good band saw and sand all the teeth marks out of the edge of the plexiglass (VERY important), if you don't do this, it will crack. Once that's done, take a propane torch and melt the edges until glossy.  If you don't do this, it will eventually crack.

I've heard some horror stories of what happens when you use hardware store purchased Lexan.  Glass broke and injured the face of the rear occupant.  It was a bloody mess.  Not good.

John, 

I looked into using the Home Depot/Loews Plexiglas and found it to be not as thick as advertised.  It was suppose to be 1/8" (.1250)  but was only (.118) or 3mm.   Problem is this thinner window will flex and possibly break with the air stream pressure, if opened in cruise flight.   I opted for the full 1/8" Plex, even though it cost a bit more and had to be purchased at a glass (auto, shower doors, glass etc.) distributor.  Loews only sells the 3mm stuff.

Thank you, Cy! That is perfect.

Got the basic shape cut.  Will round corners tomorrow.

I call this "the silent shrinkage epidemic."  I was building a deck a couple of years ago. I bought the decking from Lowes. The job took me about two weeks.  My wife looked over my work and in her typical wifely way, pointed out that a couple of boards were flawed. I've learned not to debate these observations. I went back to the same Lowes and bought three new 12x12  planks. When I laid them next to the others on my new deck they were 1/8th" shorter. The tags on both the first and second batches were identical. I took them back. The Lowes acted completely surprised as I rooted through the stack to find the longer boards. 

Of course I am aware that 2x4 has become an identifier, not a dimension of a piece of lumber. But I hadn't realized that 12 is not 12 inches in length.  

And I am still eating for my wife to notice the replacement boards are 1x16" shorter on each end from their mates.

Actually, the Lowes is too thick!   The original blueprints that Cy just sent call out .080 for the side windows.  I had heard they
were thin to both save weight and also allow people to break through if needed to escape the plane.   I had to go to a plexiglass
place to get the thin plexiglass for the Chief.

Thicker for the rear windows is probably fine...or maybe even better.  However, if you replace the Plexiglas in the sliding windows, thick won't work... The pieces I got from Wag Aero were too thick to fit in the channel of the frames, and my Chief frames are original.   The Lowes stuff I got was the correct thickness for those.   roger

That's interesting Roger,  When I put my chief windows together I used the fuzzy side of Velcro in strips for the weather striping in the channels.   Bought a 25 foot roll and cut narrow Velcro strips to lay in the aluminum frames that make up the window channels.  What was used in your door channels for weather stripping?

  I'd also be curious what the factory used as my original windows were 0.125"

I tried a number of different materials for weather strips,  until I found one that fit just right using the 0.125 plexigalss.

Hey Steve.  I really can't remember.  Next time down, I'll take a look.  Huge turnout at the Shelbyville monthly breakfast this morning.   We actually ran out of a couple of the food items...and that just doesn't happen.    roger

The original Chief sliding windows use .080 inch plexiglass with Alum channel around  top bottom and backside of the window (1 piece channel ), the leading edge of the sliding window has a 1 piece Alum stiffener channel on the leading edge.  The channel  thickness with the plexiglass installed is approx .125 inch. The channel around the window pane fit inside the channel and door skin of the door with the fuzzy material , the original fuzzy material wasnt fuzzy , it was cloth.. I have 8 to 10 sets  of the original Chief window channels from  original chief doors.  As well as the doors. If anyone needs it , I can take some pictures tomorrow.

For the front window at this point I just need to have the length. Is it 13 and a half inches?

I read the drawing that I sent you as 13 7/8 inches.

Steve.  I was out aviating today in the Chief and remembered to look.   It is just some thin worn felt.  I would not be surprised that it is original.  It could use some replacement someday soon.   roger

Oh!  Great.  I don't believe I received the front window drawing.

But that's what I needed to know!  Thank you, Cy!

[John Rodkey]

Finished product, more or less. 

The frames are pretty beat up and I am missing one or two sections.
