Pictures & rubber channel - tubing source?
I got the material in 1980 from a company called WEFCO Rubber Manufacturing Company in Santa Monica, CA.
I do not know if they are still in business or not.
Bratton's has the window channel clips but they look nothing like the originals but look like they will do.
The black felt is of good quality, not thin cheap stuff but a thick material.
The total width of the material is 2-1/4 inches before the sewing of the beading to the material.
I have two types of "beading"...one is hollow rubber, the other a rope type material. Both about 0.170 inch in diameter.
The beading is sewed into the felt material so as to have a 1/2 inch fold on both sides of the felt. When both sides are sewn, the width is then 1-1/4 inch for the assembly.
The felt then is placed into a rubber channel EVENLY. This channel is 9/16 inch wide and 1/4 inch high on the OUTSIDE measurements. The INSIDE measurements of the rubber channel are just a little under 7/16 inch wide but not by much. The height is 3/16 inch. If I recall, I had to get some that was slightly oversized or as close to the original as possible which worked fine.
NOW...you can place the felt assembly into the rubber channel two ways. The correct way is that the two sides are folded towards each other and the end of the folds are "seen" when sewed within the channel...if that makes any sence.
Once the material is placed into the rubber channel EVENLY, it is sewed down the right side, then down the left side of the rubber channel, about an 1/8 inch on both sides from the outer edge on the back of the rubber channel.
The metal clips were then attached with two tube rivets each end.
I can not remember what the original length of each completed channel is...I would think the archives could answer that question OR maybe someone has an original channel and can add to this.
I would think you would want to make them just a little short, not much though, so as when they are attached to the door, they pull up nice and tight but the archival drawings should be more exact.
The complete assembly were refered to as "Runs". I think there may have been several types...
This is what I got out of my 1929 Standard Coupe and a Special Coupe and a Tudor Sedan which is represented by A-45983-C.
The Closed Cab, "A" and "AA" Panel Bodies took A-79945-B...just how they differ I do not know.
HOWEVER...was not the glass in the Closed Cabs and Panels somewhat
thicker than the Coupes? I think it was therefore the "Run Assembly" may be different in size. The Closed Cab's is the same as T-50793-X which ='s A-79945-B.
By the way...in reviewing the November 15, 1929 and August 15, 1930 Body Parts List's, it shows us that there were 20 different types of "Run Assemblies" available for all the body styles up to that point...I wonder just how they all differed and just what was available later also for the other body styles yet to appear?
Maybe it is about time for a Technical Article on these "Runs"!
