63 Bambi Aluminum Skin Gauge

Hello,

Does anyone know what gauge aluminum sheet was used for the exterior skin on early 60s Airstreams?

Thanks,
Kamo

So 18 gauge (0.040") would be pretty close?

.040 is a standard size for 2024-T3 aluminum followed by: .050, .063, .071, .080, .090, .100, .125 etc

Looks like my local metal supply has both 0.032" and 0.040".

Should I go for the thicker one? I'm fixing the belly pan...

No, I would go thinner. The original belly skin is .025". If you use .032" it is hard to make it curl to a 4" radius.

Airstream has used .040 on the lower sheets only in recent year production.

It does add to the shell strength.

Using .040 instead of the .032 for side sheets on older trailers would add to the strength of those shells as well.

kamo, i see you live in burbank. where did you buy the aluminum? i've already made a trip out to aircraft spruce in corona to get a rivet tool and was planning on going there for my aluminum panels when i get to that stage, unless there is a supplier in the valley somewhere, i haven't had a chance to look yet.

Aircraft Spruce in Corona almost always has Airstream type sheet metal in stock, but we would suggest you call them first, just to make sure you don't waste a trip.

However, the 2024T3 that they sell usually has some scratches on it.

They are 1 block away from us.

I used .040 to replace a very long side sheet on my 63 Overlander, and found it to be an excellent choice for straight sections. It looks straight and less wavy then the original one was. Installation seemed easier as well, since the material has slightly more integrity and lays flatter than .032

.032 T2024T3 is used on the body. T2024T3 .025 is used for the belly pan, I can tell you from replacing a couple of belly pans, that the .025 is far eaiser too use and bend. It's not easy getting the pan to bend the way it needs too. In my area a sheet of T2024T3 .032 goes for $175.00 thats a 4'x12' sheet, a sheet of .025 goes for about $80.00.

It is just 2024-T3, drop the first T and you are right on. 2024 for the alloy and T3 for the heat treatment

The stuff on the sides is also AlClad, the stuff on the bottom isn't.
