2024-t3 AlCad .032 is what would be through at least 63 for the exterior.
Yep that's the most expensive. 13.75a ft.
I just ordered some from http://www.airpartsinc.com/
is the aluminum information.
They sell coil. Advantage to coil is they can stick it in a tube and ship it UPS. To ship a full sheet it has to go freight because it's oversized. Probably double to trippled the shipping charges. Shipping for 14ft of the stuff was only $27 to Atlanta.
Disadvantage is it will want to stay in a coil till you get it rivited on. As long as it doesn't get kinked once it's riveted you cannot tell the difference.
Airparts is also half the country closer and they are billing actual shipping charges (I don't know how the other company bills) I believe so it should cost less to get it to you.
The lady that answered the phone was VERY nice and very knowledgable on the materials. Took the time to answer my questions. Family run buisness I believe.
If it's a large sheet you might want to buy some of the temporary fasteners and the tool for them. Once you drill a hole you stick these in till your ready to rivet and it will hold the peice.
is the page they are on.
