metal thickness

[oldredford]

Anybody know the thickness of the metal used in the Model A? I need to replace some metal below the beltline on my late 30ccpu. Thanks...

19 Guage

You want to buy 20 gauge to make up your own panels for regular exterior metal.

You need a small amount of 18 gauge if you have some structural metal that was very rusty. The 18 is too thick to hope to do the shaping unless you have some pretty strong tooling.

New metal is much easier to use then trying to reuse a hood or roof section. I tried and the metal just did not work easy. Then I bought a sheet of new 20 and found it way easier to make the metal do what I needed.

See my webpage for more metalworking ideas.

What you want is 19 gage, for the panels you will be making. Sometimes finding 19 gage is not easy, so I put together the following info.

If you look at each gage and the tolerances, you will find that there is some overlap between the gages. The info below is out of the "Machinery's Handbook, 21st edition, page 467" for sheet metal. When you call your metal dealer, ask them if they don't have 19 gage, for the thickness of 18 gage that they do have. It might measure close enough to the upper tolerance for 19 gage to work for you. Even it is a little more, it might not be that much of a difference. Most of us would rather work with a little extra instead of less.

The tolerance for these gages is +/- .004, this was from the table on page 467 for Cold Rolled Alloy Steel (for coils and cut lengths) between 40 and 48 inches wide and between .0314 and .0508 thick.
