I need help! 
I just picked up my new red oak engineered floating floor material, and am ready to install it in my GM 4905, but I have a few window leaks to fix first.  I have the rubber and lock ring for around the “big D and little d” windows up front that are leaking, so those are not a problem, as all I am waiting for is a warm, dry day(the groundhog was wrong!).  What I need is the seal/weatherstripping that goes between the body and the aluminum stock sliding window frame(see attached pics).
[/img][/img]
Luke doesn’t have any, and right now doesn’t have a source for it either.  In the best case solution, I am hoping that somebody has some squirreled away for a rainy day, that they are willing to part with.  A lesser solution would be that someone has successfully solved this challenge using something different. 
Eventually I would like to replace all my remaining stock windows with high quality “stock looking” windows(i.e. Penninsula), but right now that is not in the budget, (and won’t be if Congress continues their current path—that is a different story—off topic) so I need a significantly lower cost solution.
I appreciate any and all help!

Steve,

Since you are planing to install expensive windows in the future anyway, could your existing windows be sealed with butyl or urethane caulk? I think you will be shocked at the price of the rubber seals, if you can even find some. If you seal the windows with caulk you may have to cut the caulk to remove the windows at the time of replacement. If your windows are hinged at the top, you could probably open them as far as possible and put a liberal bead of caulk around the perimeter of the frame and gently close the window. Since I'm not familiar with a GM 4905 my idea may not work.

Good luck, Sam

Sam,

That's the same redneck solution I came up with!  I was hoping one of the crumudgeon hoarders out there would fess up and let loose of enough to fix one window! Wink Grin

It may be some time till I can afford the Penninsula's  It looks like my employer(an unnamed government agency charged with a certain country's security) will be giving me an extra day per week off to work on my bus--through the end of their fiscal year. Grin

Realistically, it may be a couple of years until I get new windows, so something near the original would be great.

Thanks!

Steve

This is what we used on all of our windows. Works well, and not problems. Used to have the rubber gaskets and they leaked like crazy.

Steve,

That rubber gasket I believe is the same on a 4106.  Five years ago it was impossible to find.  Having it custom made would be pretty expensive but possible.  I know there are companies that do this for a business.  I have some contacts and can make some calls.

Mark,

I plan to seal one window this weekend, so I will be removing the original "rock-hard" rubber seal around that one.  Hopefully, I can salvage enough peices so that I can get a good profile.

I searched the web, and this BBS, so I think I have a couple of possible sources for low-volume manufacturers that might be willing to extrude it.  I know most of the expense is in making the die, but maybe a die exists that is "close enough."

Thanks!  I would still appreciate help w/any contacts you have.

Steve

My father is a prolastimer (petroluem and chemical) engineer and is a partnerin a machine shop that makes dies.  At one point he owned a fiber optic manufacturer that had a dozen extruders.  I'll make some calls tonight.  I'm sure he's lookin' for a project!

Thanks Mark,

My dad owned a machine shop for 25+ years, and made the dies for Graham Engineering for the first quart size plastic oil containers for Quaker State oil.  I grew up working every position and every machine in the place except boss!  Sadly the shop has been gone for 15 years, and Dad for 8.

UPDATE--I didn't find the seal I was looking for----BUT I found the source of the leak.

Some dimwit removed the stops on the windows so they would slide further, and yes the screw hole goes completely through the frame, and without the screw in there---LEAKS LIKE A SIEVE! Angry  A good outer seal would have prevented significant leaking like I had, but still may have leaked.

I'll give you two guesses who the dimwit is!

Maybe I'm talking about the wrong thing ( I do that now and then) but I bought all six of the rubber molding (seals) from Luke last year. He was able to provide all the window and baggage door rubber all the way around on my 06.
