    Rebuilding roadster windshield

    Would like to know if there's any info out there, such as an old article, on how to replace all the rubber in a 6-cyl roadster windshield. I have all the parts from Moss.

    Re: Rebuilding roadster windshield

    If you're using your original glass, you may find that the new glazing material is too thick, making it next to impossible to set the glass in the frame. I ended up going to a local auto glass shop and they had thinner glazing material.

    Use the glass and frame assembly to position the posts before installing the scuttle seal in the frame. Shim the posts and tighten them in place, then install the scuttle seal and install the glass and frame. That way you know you're not twisting the glass.

    Good luck.

    Plan on buying the new corner bracket set, if you have not already done so.

    It's a tedious job, but immanently doable; being in the right frame of mind, and if you find it necessary, WALK AWAY, and return when you're up to it.

    Here's a link to some pictures I took when doing mine__I'd had the frame rechromed, new glass & all rubber. I was somewhat amazed by how hard you could influence the frame & rubber into compliance with a rawhide mallet...

    Randy, thank you for the link to pix - very helpful.

    I found these (Moss from AHspares) do not fit; neither does the filler strip:

    Re: Rebuilding roadster windshield

    Hope it goes well for you. We did this on the 100-6 earlier this winter, so the memories of the experience are quite fresh. The glass that we used came from a seller in the US and appeared to be an original piece in quite good condition. The old glass in the frame was badly cracked, but it still had the sealing strips in place to show us how it should be done. The new glass was a little smaller than I would have liked (1/2" or so in each dimension), so it did not fit as far into the frame as a somewhat larger piece would have. We reused the rubber spacer strips that seat in the channels; they were still in good condition. The original seal around the glass was very thin, and the glazing rubber from the local glass shop proved too thick to use. What did work was a roll of that black rubber tape that one uses to stop leaks. That tape is sticky on both sides, and if that is a problem, one could put a layer of thin black electrical tape over it so that it slides into the channel without sticking.

    We had a couple of old frames to pick the best corner brackets from. A number of the screw holes had to be drilled out and retapped. We also found enough of the tiny little screws to reuse. Certainly, replacement new brackets and screws would have saved time. But they were weeks away in either California or Britain, as are most parts that we have to order. A couple more hours of careful work sufficed to salvage the screws and brackets.

    The scuttle seal also proved difficult to install, because it had deformed in the package and also because it could have been closer to the desired profile. It wanted to pop out of the channel when placed on the car. A little heat and temporary tape to hold it in place helped.

    In spite of the challenges, the finished job looks fine. As with most things on these cars, every little step proves interesting.

    It's definitely not a task you should attempt after talking to a divorce lawyer, the IRS or an insurance agent handling your claim.

    At least for me, the exact right moment had to present itself (note the sizable gap__1 yr/4 mos__between taking it apart for replating and the courage to reassemble...) before I would even attempt handling a piece of safety glass and "new chrome," not to mention beating it into submission with a rawhide mallet!

    The ones I got from Moss didn't fit either. I was able to reuse the old ones. I was using new glass, so the sealing rubber fit.

    Steve
    i believe i found a video on it from u-tube. maybe the matthew guy from Australia.

    my new corner brackets did not fit at the top. bottoms were ok. the video had said not to throw the old ones away. good i followed that advice. i used new glass. the new glass and seal went in pretty well with some taping. the seal was wide so i did not worry so much about keeping it exactly straight. when i was done, i took an 1/8" pc of steel and put it against the frame. then put my knife on the other side. slid it all the way around on both sides and left an even amount of rubber.

    not a bad job just a little bulky.

    Seems I recall the seal (1-1/2" wide rubber) was a continuous strip, with just a single joint (I placed at the top, IIRC) not mitred at each corner...




    PS: EASIER to put the rubber around the glass and push the channel over it, and a mixture of alcohol & water for lube (and don't be afraid to use a rawhide mallet...)

    Re: Rebuilding roadster windshield

    It is a continuous strip. Maybe the Aussie cut it into pieces. Will follow up when I get the pieces back from the platers and re-assemble it.

    Informative thread. I have contemplated replacing the glass on my BN6, which although not cracked, it is not perfectly clear anymore due to discoloration and flaws in the safety layer. Wondering if it's possible to send it out to a specialist for glass replacement?

    My original glass, which is currently out sitting in my living room, is .23" thick. The cheaper Moss replacement is closer to 3/16". Today a friend and I picked up one of the more expensive ones at Moss. It's about 1/4". I'd only consider that one.

    I think the thicker one is TripleX glass?

    one thing when you put it back in.

    the seal that goes down to the body:
    i kind of jammed mine up in there before i cut it off figuring it would shrink over time. it seems i ran in to that before on another car. BUT, this one has not drawn up. if it has, it is very little. So i still have some ripples at the end on the curved part. Maybe someone has a better system on here.

    Re: Rebuilding roadster windshield

    Randy,
    Referring to your picture:
    1) Did you miter-cut the rubber seal at the corners of the glass, or was the seal stretchy enough to just force the frames onto the glass over it and have it wrap around the corners without any cutting?*

    *Edit - never mind, I see above you didn't miter it. I should read more carefully.

    2) The part you're holding away from the glass - what did you use to cut it next to the frame.

    my memory sucks but as i recall i stretched the rubber over the corners pretty easily. the glass corners are not real sharp.

    on the rubber:
    one reason i cut it back to an 1/8" reveal, i had less of a bubble of the rubber at the corners. either way if you cut the rubber at the highest point (see Randy pic above) to the metal; let one piece lay over the other and run your knife thru both pcs at one time. run it from the frame corner out to the the inside point where the rubber overlaps. pick out the loose pcs and you will have a perfectly fitting miter. i used a dab of clear silicone at the corner.

    hope that is what you were asking

    OK, DD, I now understand that you mitered the corners. Not just squishing the corner seal in place with the metal frames.
    It appears Randy squished the continuous strip in the corners with the metal frame pieces.
