It has been a busy six months since I started this thread.   My side windows are green, and the windshield is not green- it is solar gray.   Yesterday I ordered two solar gray side windows with UV-IR control.   Recently I read on another thread that drilling the window mounting holes large is a good thing.  Pre-drill with 1/8" then expand to 1/4"?

I helped do a door window on a Beechcraft.  They made a point to close the door when you let the window sealant set up.  I would think Mooney would be the same.

There needs to be clearance around the screws. Drill an 1/8 inch hole and use your countersink to countersink the hole then drill to 3/16. You have yo countersink it enough for the dimple to fit.

I'm pretty sure the procedure is in the maintenance manual. Check there before you start.

 DRILLING TIP

 

NOTE: Windshields installed with flush screws through dimpled holes in the skin need special attention. When drilling the Plexiglas being held in place, the windshield will be resting against the dimpled upset-holding it slightly out of position. To compensate for this, the pilot holes #40 should be drilled  to the outside edge of the existing holes.

They will lineup after the hole is drilled full size and countersink!

This prevents puckering of the metal on the finished job.

At each annual over the past three years we had windows replaced. The first was the windscreen, followed by the pilot and door and this week the two rear. It's not a job I would tackle on my own, but to each his own. The overall cost for the installation was not terribly much.

The technical detail explained by Shery/Paul explained the puckered ugliness of my M20C’s windshield installation... done in the last century...

Thanks for sharing the tech details Shery/Paul that info will go a long way and help many!

Best regards,

If doing this, I would do what one person did and cut a step on the edges for a flush fit.     You could also by a certified 4x8 sheet and get to cutting.

I did my pilot and passenger side this past October.  Took a full day to do, but was not hard at all.  Needed two people to do the installation when actually putting the screws/nuts in, but was easy enough and I'm NOT mechanically inclined.

Pilot side when done:

I've had such good results using the Novus plastic polish that I got from a Harley dealer that I never expect to need to replace a window due to crazing. I even used it on our truck's headlight lens that had taken a lot of abuse from sand on the road in winter. That took a long time and made me wish I had purchased the coarsest grade, but it worked in the end. I've also seen it for sale at the Rockler woodworker's store for getting really fine finishes on carpentry projects as well. I was having a bit of trouble seeing through when the sun was low and a couple hours polishing cleared it up.

Just saying.

Page three of my interior project has info on replacing the windows. 

Do it when it’s hot so you don’t crack anything. 

Use fresh chem seal.  The stuff really does expire.

Thanks @hmasing- but I don't see your photos.   They seem to have been ground up in the bit mill and spit into /dev/null.   I'd like to see them.  Anybody else see them?

Open the attached thread and scroll through it, lots of pictures. Just no pictures in the first post. Keep reading down, pictures are there . . . .

Hank, how does one open the thread?   When I quoted it to write my reply the pictures weren't there as I deleted the frames.  Thx.

Hank- Brad's post isn't the one that I want to see photos - it was @hmasing's post.   The photos are missing above.  Do you see photos there?

I dropped them in from google photos, so permissions may be hosed.  Here's the album with all the pictures I took from that project, please let me know if you can see them?

I can see them. Your old glass looks very similar to mine. I noticed you still have fiberglass under the windows. I would do SB-208 while you have the panels out. Hopefully your old windows didn’t leak and your new windows shouldn’t if they are sealed correctly.

And what color glass did you go with? Can you post a picture of new and old side by side? Loved to see that comparison.

Knocking that out this weekend - plane has been down since this project for a panel update as well.

I went with the light gray from Great Lakes Aero Products. You can barely see the new windows compared to the old ones - it's a major safety improvement.

Thanks a bunch Hans.   I've had the door panel apart but I haven't really looked at the window on the pilot's side.   Good to see what that area looks like. 

In my bird the windshield is clear or slightly tinted.   The side windows were crazy green.    For replacements I went with Solar Gray with UV+IR control.

Yup, that's what I did I think, too.  This is the new passenger side window looking to the rear of my plane, and the old window.  I stripped some corrosion and primed it for when I get the old girl painted next year, hence the green.
