Hi All,

I have what was a perfect 1960 TR3A or 1962 TR3B windshield. Not sure which=
, but it was pristine. Unfortunately, and tragically, I had it in the house=
 for cleaning and it was accidentally knocked over. When it hit the hardwoo=
d floor it cracked all over the place. The cracks cannot be felt on either =
side so the glass must be in three layers, or laminations. Is it possible t=
o have this repaired or am I out of a perfect windshield?

Sure, it's possible.  First you melt the glass down ...

Which leads me to an odd question : Does anyone know what the manufacturing process would have been back then?  Roll the glass out
flat and then curve it during the tempering or laminating process?

as i recall...and im old
first thing to be done was to build a polished steel buck.the glass would b=
e cut to shape.then carefully clamped to the buck and put into an oven wher=
e the glass was heated until it slumped and settled on the buck. this is wh=
y you often saw distortion.after the hot slump the glass was allowed to coo=
l slowly for annealed or quenched quickly with "cool" air for tempered glas=
s. very little tempered glass went into laminated car windshields.
it required 2 bucks one for the outer light and one for the inner light.bot=
h having slightly different radi.smart folks developed bucks with a crank t=
hat could change the curve slightly if it was not a compound.
then one light of glass would have the PVB inter layer placed over it. it w=
ould have been slightly oversize for the size of the glass.
carefully 2 guys would place the second light of glass onto the first glass=
 & PVB so that the edges lined up properly.touch at one end and kinda roll =
the glass into place.
manual roller firm but not heavy across the glass.
there would often be small air pockets visible at this time. and even today=
 in manual lines you still see some small air pockets at this stage.

the PVB is not intentionally sticky but does cling enough to hold the glass=
 together now
the assembly then as now went into an autclave stacked on edge.
steam is pumped into the autoclave and pressurized to force the 2 lights of=
 glass together. the hot steam softening the PVB and allowing it to absorb =
the small air pockets that may have been present and take up irregularities=
 in the curve difference of the 2 glass lights..
allow to cool gently.
knife off the laminate that was oversize.
its funny how the PVB sucks up some of the small air particles. i have ofte=
n though that's why we start to see bubbling around the edges of old lamina=
tes.
there are i believe, some old time fabricators who can still make laminates=
 this old way but i expect they want big bucks.
im not sure when better automated machinery took over. it had to have been =
after the war. to start producing cars at the rate we did this was not an e=
fficient process.
today we are messing with "cold bending" glass. trying to get it to take sh=
ape using less energy. but like vacuum formed insulating glass we are only =
in research and development.
we recently ran a series of tests on some glass products here with general =
contractors, architects and building owners present.one contractor noted it=
 was the boring day he had spent watching a test.
