I have purchased the bottom metal channel for the door glass for my 1927 coupe and the channel rubber seal. Can someone walk me thru how to attach the channel to the glass? The glass will be tempered. I assume I should not apply any pressure to the channel to "clamp" it to the glass, just rely on the adhesive.

I will use laminated glass for the windshield. It is about $200 more to use it for the other windows.

I have used a cork around the glass to set them in and also used an epoxy that I bought from the car parts store, the epoxy was over kill since they are not power windows. The cork was gasket material from the parts store that i cut to length and width.

The glass is set into the chanel with glass setting tape. This is shown in the Ford Service Bulletins. My personal experience is mixed. It is better left to an automotive glass shop to do. You crack it and you buy another piece of glass. The glass shop breaks it, they replace the glass and try again.

I thought the rubber seal goes into the channel and the glass fits into it. If that is so, what is the glass setting tape?

Bruce, glass installation is shown in the Ford Service Bulletins no 8, vol 4, pg 61 for a generic door window. The 26-27 coupe door glass is a little more complicated as there is also a rubber weatherstrip in the bottom channel that seals against the door opening when the window is in the up position. That weatherstrip needs to go in at the same time the glass goes in the metal channel. The correct metal channel is the 28 model A pickup door channel, it has an extra slot for the weatherstrip. If you do not install the weatherstrip, dont worry, there should be drain holes in the bottom of the door to let the rain water out.

What the Service Bulletins call fiber retaining strip is glass setting tape. It is a gasket like tape with a sticky side that adheres to the glass. Comes in different thickness, available at automotive glass shops. Or you can have the glass shop install it for you.

Bruce,

I have done this several times with different old cars. Most recently on my '22 Center Door. Changed all glass to safety. An old glass guy suggested I do it this way.

Use the glass setting tape. Sticky side against the glass. I use a lot of glass cleaner, Windex type, and get the channel and the outside of the glass setting tape wet with the cleaner. Pound the glass into the channel with the cleaner providing some lube. Once in, leave it overnight to dry. I never had one come apart. Never broke the glass.

Good Luck,

Rich

I ordered 8020CH (metal channel) and 8020 (rubber seal) on page 205 of Lang's catalog. These are shown in the attached photos. I had not looked closely at them until today. The rubber seal has a lip that is to prevent water from getting inside the door. The glass from my coupe is also shown.

I had assumed the rubber seal fits onto the glass and then the glass is inserted into the channel. I now believe this will not work. There is just not enough space in the channel as can be seen in the one photo.

Has anyone used the rubber seal?

Can I just use glass setting tape and forget trying to seal out water?














can

I forgot to include this photo.

Bruce,
The new channel and the seal you have are the wrong parts for your car.

It looks like your old glass channel is in good shape and can be reused with new glass.

If you give the old window with the glass and channel still together to the glass guy he should be able to take it apart and reuse the old channel to install the new glass.

I cannot find the rubber weatherstrip in Snyders Antique Auto Parts catalog, it may not be available anymore. I am not using a weatherstrip as I did not give it to the glass guy when he installed the glass in the channel and now it is too late.

This is a no brainer, just give the old glass window with the channel to an automotive glass shop and let him take care of it.

Really, let the glass guy do this.

I am serious, give it to the glass guy to do.

I'd listen to Jeff.
I believe glass setting tape was a rubberised material, that once set in place, was cured with Kerosene or some such to fix it to the glass/channel. These days the glass shops have better mastics to do the same job. One of the Sikaflex products is the go-to for the blokes who fitted a replacement screen in my tourer. It seals the glass in the channel and prevents any chance of water penetration and subsequent rust.

Allan from down under.

Glass setting tape comes in different thicknesses, some is rubber (using that term loosely) and some may look like fabric/rubber. Depending on the thickness of glass and channel it is installed in, you need to buy the thickness that will not crowd your glass and will still hold it in place.
