1950 opening here Windows and glass breaking

[Bowmans]

Edit - Spell check mangled the title. Meant "Hehr windows"

I posted last night to my blog that I finally got 2 working windows rebuilt. Woke up this morning and one is now cracked. Blog entry posted below. That mans 3 cracked windows out of 4 rebuilds. Not sure what I am doing wrong at this point. All of the stress cracks are in different locations so I am assuming the frame/seals are putting the window under too much stress. I have tried glass at the original exact size, slightly smaller and with a beveled edge to fit "looser" in the frames.

Does anyone have a link to someone rebuilding these one piece frame type windows? I was unable to find any searching both window forums and trailer model forums. At this point, I am considering using Lexan. The seals will still be tight with the movement and I won't have to worry after every bump that a window may have cracked.

Thanks for any help on this.

I've been making progress on my similar windows. Your "PITA" post was a big help. Great tips and your info gave me the gumption to dive in.

I had a heck of a time getting the windows & hinges mounted back in the trailer. Just a bunch of fiddling was about all I could make of it. I don't know the "best" way to do it...but I installed the hinges and then screwed the windows in to them.

While doing this a couple times I heard a tiny little gritty sound as the screw hit the glass...then one more little turn and the glass broke. Which makes me wonder how many of the other screws are resting on the glass and may eventually help it the windows crack?

Is it possible this is what's going on with yours?
