Specific steps to replace (outer) side windows - de-rivet?

[B2C2]

thanks for the clarification. Where did you source the seals and the new windows?

In may 1969 T337D, you

1. Pull out the side trim pieces, and
2. The INNER windows just have rubber seals around them*.
3. The seals just sit in simple press-in frames.

No riveting, no hassles.

For turbo/double windows you want the window rubber gasket to be non-symmetric, to maximize the distance between inner and outer window. Otherwise with vibration they will rub / haze at point of contact.

awesome thanks for the help. I have a 1969 T337D so that's perfect. I am going in for annual in two weeks, assuming no major issues, I will tackle this as a "while you're at it".

With this annual, I've pretty much decided to go with clear OUTER windows.

Just need to confirm same as front and door as already as done more recently.

Reasons are:

0. BY generally parking facing north, angle of incidence on windshield is better than tint!

1. While 'smoked' might look cool, loss of light & contrast at night and IFR

2. Except for pilot side and door, other windows are under wing and shielded from sun.

3. Inner windows are easy to pop in/out in just a few mins.

3a. Inner windows under wing may be just fine. We will see.

3b. Easy to redo INNER windows later on

3c. Inner windows non-structural, so can buy any old UV plastic anywhere: $25 for fancy UV + tint vs $200 per window

3d. Can change INNER to tint or clear easily and inexpensively as desired at any point

[n86121]

All original side windows from 1969.

Windshield was replaced to match,. circa 1989. It's still fine. Tied down facing NORTH.

Originals were apparently green tint....

...So I guess I will be going green tint!

As is my nature, I keep drilling down until I hit bedrock.
Then I go a bit further until the drill breaks.

Then I grind the bit into the rock for a while too.
Then I throw away the damaged tool

Then find the next thing upon which to obsess until exhausted.

==========

It seems pretty much any basic acrylic blocks pretty much all of the UV anyway.
UV a the shorter end of the visible spectrum around 400 nm and below (nanometers!).

So what is protecting your interior is modern materials chemistry more than anything else.

---

Gray tint blocks flatter across the spectrum of visible light: Reduce all wavelengths X percent.

Green tint blocks brings green light down faster, the most 'visible' part of the spectrum.
Also may knock UV down faster than gray (at the same transmissivity).
While allowing reds and yellows to show through better, such as perhaps dusk and dawn.

IR (heat) is at the red is at the long wave end of the spectrum.
Whether gray or green knocks down more IR is hard to determine.
Probably the same.

So the decision seems to boil down to fashion choice.

The Visible Light Spectrum

Color Wavelength (nm)
Red 625 - 740
Orange 590 - 625
Yellow 565 - 590
GREEN 520 - 565
Cyan 500 - 520
Blue 435 - 500
Violet 380 - 435

Uses for Different Tints:
Following is a handy tint guide for choosing sunglasses. ...
Green tints filter some blue light and REDUCE GLARE,
while offering HIGH CONTRAST and visual SHARPNESS.
Shades of green also tend to REDUCE EYESTRAIN in bright light.

----------

The three most common (SUNGLASS) tints are gray, gray-green, and brown.
Gray (neutral density filter) is recommended because it DISTORTS COLOR LEAST.
Some pilots report gray-green and brown tints ENHANCE VIVIDNESS,
minimize scattered (blue and violet) light,
thus ENHANCE CONTRAST in HAZY CONDITIONS

That will all be on the test.

just thought id follow up and thank all who provided information on this window replacement. Annual didn't turn up any major problems so I ordered the parts from great planes and my mechanic installed the new pilots side window and seal. Job was exactly as described, no rivets needed to be touched and the new window looks great. Thanks again.
