glass for windshields
 

I was wondering if anybody could tell me the thickness of the glass for windshields on CMP s or Willys MB/GPW s? One of the local shops is keeping 6mm (1/4) sheets of safety glass on hand. Wondering if this. May help anybody.
He has also has patterns for vehicles from the 30's and up. I plan on visiting his shop to see if he has anything military.

CMP is 1/4 inch
 

Most local Speedy Auto glass can cut safety glass for your windshield at about $70 per window.

Would love to hear that he has CMP window patterns .......

Having a short conversation with an obliging manager will help you get the proper sealer and tips for installation and he will gladly do them for you for $$$$.

Without a pattern get yourself a 1/4 sheet of cheap plywood and start measuring and cutting until you have a blank that fits perfectly then walk it over to the glass shop.

Good luck

Cheers

Thanks Bob. He has quite a collection of patterns that he got out of Virginia. I'm gonna take a look. He has one for a 46 Willys. So I hope he has some more. I don't Think he knows exactly what he has. I'm going to try to get over there this week. Any suggestions as to what I should look for as names? I'd be surprised if they listed as CMP or military nomenclature?

When I did my 12 Cab Ford I simply went into Speedy auto glass and asked them to "fit this". The next day I walked out with a completed windshield.

For windshields you must, of course, use AS1 glass. As well, if you are going to get a safety done at some point, get the glass place to watermark the AS1 marking onto it, otherwise you can fail the safety.

Some stiff cardboard for a template works out just fine.

So the big question for those of us with recently retired vehicles, is it better to go with NOS or newly cut glass?

I'm not a stickler for a maker's name mark in Toledo or Otumwa, but I don't necessarily want something that is going to cost a fortune to ship and risk breakage.

I doubt......
 

Hi Jason

I doubt very much if a collection originating in Virginia would have anything CMP related..... but he may have some US military patterns such as CCKW, Jeeps, etc.

Keep in mind that ALL CMP were manufactured in Ontario...... I suspect that the Chev CMP windows were made by Duplate in Oshawa which was bought out by PPG glass.

Makers mark/ AS1 marks
 

In regards to AS1 and production markings.... Panes are cut from larger sheets. Each corner has marks on larger sheet. If it is required to have AS1 markings, it can be cut from the corners of each sheet. If you wish a blank pane, it can be done from elsewhere.

Any glass I have had cut from AS1, the glass place applies an acid etch of the AS1 marking. Not a big deal and it does not cost extra if done at the time of cutting.

Short side story.

With the Iltis, we used to have to order the glass from the depot (Edmonton in the case of the Western Army). You would always order 2 or 3, or even 5 because half of them were going to show up broken anyway. If you ordered 5, then they might sandwich it in plywood, or even a re-usable crate. I ended up putting in a TFR with the suggestion that the glass simply be made a KM (procure locally) item, since we could get them cut just as cheaply downtown, and without all the breaking and loss. This was adopted. Somewhere along the line I think someone else did a TFR to get it back to national stock, likely because you could not buy AS1 in downtown Bosnia. The pendulum swings.
