I recently purchased a 26 Roadster. Not sure if side glass wind deflector is a proper description. Any way the passenger side one is mounted and works well. The drivers side glass laid on the seat and the brackets are in place. When I try to install the glass even though the rubber pads are in place. The glass seams to rotate the clamp and fall out. I see the passenger one has some form of glue used. Any advice appreciated.
Do you have the original style of wind wing brackets as pictured in this thread: http://www.mtfca.com/discus/messages/80257/90542.html?1241368785
or is it any other style of reproductions?
Could be the wrong thickness of glass was used. If the glass is to thin it might not allow the clamps to have enough pressure to hold the glass in place. You might try thicker rubber gasket between the clamp and glass or adding rubber shims. Or thicker glass.
The pictured wind wing brackets are just like mine. I compared the glass thickness between the two sides, it is the same. The glass looks like it maybe to thick. Only the first few threads of the screw are grabbing. I don't know how tight I dare tighten the clamp screw before the glass breaks or the screw strips. May be i'm not tightening enough. Is there some way to gauge how tight to tighten the screw before I break very old glass. Would a little dab of clear silicon between glass and rubber pad be a good idea?
If the glass is not safety glass, it needs to be replaced. Plate glass shatters and could cause severe cuts or death if broken in an accident. Same applies to the windshield. Perhaps something is bent. The clamp must be tight on the glass to keep it in place.
I have a different kind on my car, and the glass has fallen out a couple times.
Not that difficult to drill holes in laminated safety glass. If you like the look of plate glass then consider drilling plate glass than then having it tempered (just like the side windows on modern cars). That Is what I did on the "wind wings" on my '27 roadster about 30 years ago. No problems. Yes it will cost a couple of $ more to do, but it sure baffles people!! Any good glass shop can do this for you.
Thanks guys. Glass is safety glass. I put a drip of medium lock tight on the threads and tightened screw as tight as I could . seems to be just fine. I just needed to get more aggressive tightening.
Maybe longer screws! If they are only grabbing a few threads as stated above they might strip out.
Thanks Mark I did replace the 1/2" screws with 3/4" screws. They seem to be fine now.
