How to make plexiglass windows?

I have some 3/8 plexiglass sheets and I have an idea to make replacement plexiglass side windows for my 67. 


I have a vent window, then the door glass and a rear corner window..


They are slightly curved and I know that by gently heating the plexi. I can "form" it over the curve of the original glass. 


What I need to know is what temerature to heat it to... And  for how long.


I have access to a large digitally controlled industrial oven,  It can set a temperature to half a degree from 150 F to 1000 F


I'm thinking it doesn't need to be super hot, maybe 200-210 degrees?


Just enough to soften it a little..


I am building a 67 Galaxie


460/4speed/4.56 Spool


It's stripped, lightened, gutted.


Measured weight so far. 3575 lb.


replacing the glass on the side will save me another 100 lb.


thanks!

I don't think I would use the Plexiglass. Lexan is the one to use. It is less brittle then the Plexi and 1/8th inch thick would be plenty heavy. 3/8th's is way to thick and you'll have a hard time getting it to fit the window channels.

 The 1/8th inch stuff will form itself to the window channels curve also without having to heat it. I will quarantee you will never "gently" heat the 3/8th plexi, consistantly, to a point where you will get a smooth bend put into it.

 Get some lexan... My advice.

I agree.  I used Lexan for the windows in my van.  And if you're really serious about lightening, ditch the wing window all together.  that's what I did.  I also lost the crank mechanism, as that is unecessary weight.  My windows are held in with dzus fasteners.  Make a template out of thick cardboard first, then cut the lexan.

Thanks!


I can get some lexan pretty easily. 


I just had the 3/8 plexi laying around..


I already have the door and window mechanisms already taken out.


I was planning on replacing the vent window and the door glass with a single piece of plastic.  The problem, or maybe it won't be one is that the car is pillarless, the door window floats.. so I don't have channels to support the replacement piece...


Should use 1/4 inch?  So it won't be too flimsy.


thanks!
