Removing the glass from the sash

Several months ago I posted a question on how to remove the glass from the sash. Here are the responses: Sash Glass Removal Since I was not going to reuse any of my old glass I decided to try taking a 2 X 4 and a hammer and tap the sash off of the glass. Using a little caution I had no problem getting the sash off. The picture shows my removal technique on a refurbished sash and new glass.



Sash restoration

The condition of the sash has a lot to do with the storage of the car and the climate to which it was subjected.







This is an extreme example of a glass that was installed with setting tape made from a fiber product that was glued in place. Needless to say it took a lot of work to remove the fiber/glue mess. Normally you are only removing a well aged even brittle rubber material.





Some times you will need to repair rust through areas. After media blasting the sash I like using the West System to repair the holes. Put tape over outside holes in the sash and cover the inside surface at the bottom with about 1/16" of fiberglass. After it sets up put the sash on its side and brush on a thin coat of fiberglass on the side next to your bench. When it has dried turn it over and do the other side.





The finished sash now has a smooth, waterproof, durable, inner surface.



Paint the outer surfaces of the sash with silver Por 15.



Reinstalling the glass in the sash

I fold my setting tape in two. To learn more about setting tape read the following post: Rear side window removal

With the tape well creased position the tape in the groove of the sash. Center the sash over the glass and tape the sash to it. Place the glass on a rubber pad covered with a blanket a couple layers thick. A towel would also work well. Using a rubber mallet lightly pound the sash onto the glass. When the sash is well started onto the glass use a block of wood to more aggressively pound the sash all the way down.


Excess setting tape can then be trimmed off with a wall paper knife. Protect the glass from being scratched with a large putty knife slid under the tape.



Good luck, Mike
