Securing Bottom Metal Channel to Side Window Glass

I have 6 new glass side windows to install in my '31 Slant Window Model A. The bottom of each glass panel fits in a metal channel that is lined with a rubber molded piece. (Purchased a roll of this rubber from Snyders) What type of glue / sealant should I use to hold these three pieces together...the metal channel , rubber liner and bottom of glass window ? Thanks for any help !
 
most lower window channel is held on by the friction fit of the packing between the glass and the channel. no glue or any kind of adhesive.
i put the window upside down on a clean smooth solid mounted board and drive the channel on evenly with a wooden mallet.
they can be tight.

if the glass is loose in the channel then you have the glass too thin or the packing too thin. a glass shop can do this in no time flat for you. if need be.
 
Thanks for the reply. The 1931 Slant Window uses a different material in the bottom metal channel. Other Model A's use a black neoprene bedding material that swells when oil is applied. This swelling helps to hold the three pieces together. This rubber material for the Slant Window model is not the same product ( seems to be plain rubber) so I think some kind of adhesive is needed. I don't think a tight fit / friction hold will do.
 
Where did you get the info that the slants used a different bedding product,and that oil was used in the process? That sounds more like a story from FB or Utoob.
 
you could be correct, have never worked on a slant window 31, but i would be skeptical on that bit of information.

if you decide you want to glue it in. I would go to the glass shop and buy a tube of windshield urethane (some times it needs a primer for the glass aswell) put it in the calking gun, clean the channel and the glass with lacquer thinner, wipe it dry and clean, put your bead of urethane into the channel. make sure it is rite as it will never come back out if you have applied it as per the direction of the manufacture.

nothing else is gonna hold it for any length of time.

ps,
the one issue i see with the urethane is it may not want to stick to the rubber packing you have, if it were me trying to cobble this together i would leave out the packing and fill the channel with urethane to compensate.

oh and an fyi the packing on lower window channels is not oiled when it is put together.

Yes, the S/W bodystyles use a rubber that has the Window Seal already installed in it, but it installs the same way as the regular rubber setting material. The trick to this is to soak the rubber in light-weight motor oil to get it saturated. Then push the channel over the edge of the Glass. Once the Channel has taken set, spray the Channel Rubber with Brake Cleaner to remove the oil residue. Once it has dried, it will be very difficult to remove.
 
Well Snyders has the details on their website for this glass bedding material item A-3401-X
The Slant Window material item A-3401-SW is different
 
Thanks for the replies ...Brent & Old Ugly ...I'll give these a try and see what works best. Will post my results Have a great day Thanks again
 
i would go with BRENT in 10-uh-C , i have never worked on S/W.

in the shop we would never have put oil on rubber parts. sorry for the bad info.
 
I know the slants used a bed setting rubber with a lip seal,like a flap made onto it to seal the opening when the glass is up.I haven't touched one on a slant in years,still can't figure what the three pieces are.Years ago I used some oil on a Tudor,it turned the bed setting tape into a black slimy goop.Of course,rubber products now are a lot different now than they were 20 years ago.Between the repro window channels not being quite right,and the glass having varying thicknesses,I went to just setting them in the butyl.Squirt the stuff in the channel,set the glass in,and make sure it stays square until it sets up.If originality is an issue then that way is not for you.
