Ideas on how to fold this?

I agree.... about the internet!

I just went out and put my metal gauge (U.S. standard gage for sheet and plate iron steel) on the lip of my front fender at the fender well (1993 Grand Cherokee). I could get the metal into the 21 gage slot (.0343)...so if i removed the paint it would be thinner. By the way 22 gage is .0312 and 18 guage is .050...these are based on the U.S. standard gage for sheet and plate iron steel.

If the metal is galvanized it will increase the measured thickness of the metal but imparts very little strength to the metal as it is a protective coating....like paint (but more durable).

FYI the fender on my 1955 Chevy truck is 18 gage. Yes I went out and put the gage on that also. My chevy fender weights much more than my Jeep fender. 18 gage is 2 lbs per sq. ft. 22 gage is 1.25 lbs per sq ft. so it is almost twice as heavy.

The average sheet of 20lb copier paper is 0.0038 inches thick not .00598 as you state. But you are comparing paper to high strength metal...apples to oranges. So don't forget that high strength metal is stronger that the same thickness of mild steel, there for a thinner metal can be used. But just for fun put 5 sheet of paper together and see if you can poke your finger thu it now try that on 22 gage metal!

I just used my digital calper and converted it here: http://www.onlineconversion.com/gauge_sheet_metal.htm

Like I stated U.S. standard gage for sheet and plate iron steel.". Mind you I was stating the normal US standards on how cars were made. My post did not say every car, truck or SUV was made to those standards. I was just postiing what my books and training have taught me over the years. There is a variance allowed in the manufacture of sheet metal. Again I was stating the "U.S. standard gage for sheet and plate iron steel" and going off what my gage (not a caliper but an actual gage) read. So yeah you probally have exactly what you said!
I just took and take exception the the statement that " 18 gauge is the universal autobody thickness". In my training this is not a true statement. And I thru out the door skin thickness of 28 gage...that is actually used by some car maufacturers.

Hey surf2snow the images aren't coming up.

28 gauge is absolutely absurd. You would be able to bend 28 gauge titanium sheet with your bare hands like it was nothing. Let alone steel.

Titanium is no wonder metal here. It's only as strong as steel....just not as heavy. It also doesn't corrode....so thats a plus. however it is flammable so I wouldnt see car people putting it on a vehicle in thin sheets.....not to mention its hard to work with, and destroys anything but grinders and carbide; especially if it gets hot and hardens.


Why was titanium mentioned again?
 
Just a comparison, but sorry it was a bad one. Although titanium has a very high strength-to-weight ratio, it wouldn't matter in this application since we're talking about a designated thickness. Typically titanium has a tensile strength of around 170,000psi. So let me get another one.

17-4PH and 15-5PH stainless steels. Both can easily reach 180-200,000 ftu if they're treated.

My point is, anything at that thickness can easily be bent by simple human force. There is no way automotive manufactureres use it in producing their body panels.

Didn't mean for this to turn into such a stupid argument :dunno:

ok I get it....I appoligize... only 18 gage steel is ever used or will ever be used in car manufacturing and titanium is bad...or good...jeez put 28 gage metal on a car what will they think of next...putting plastic on a car? Or how about using glue to hold body panel together....wow thats way out there.... Oh wait they do....mmmmm. lol I think you fail to grasp the concept of high strength metal, structural integrity as a whole unit and the overall design of crash worthiness, due to the engineering, lighter metals can be used along with plastic and composite materials.
I can agree to disagree... by the way did I type 28 gage...hahaha should be 18........whatever

Why was stainless steel mentioned again?

Forget it, this is stupid.

To the OP, did you ever get it folded?

Yeah, I managed to get a piece of 3/4 x 3/4 box clamped to the back of it. I'm going to have to go back and fix some small dents since my body hammer has a claw on the back

And X3 on this getting way OT, I mean i for one am glad most of the panels on my heep arent epoxied together. All this new chit just makes the cars more disposable. Yay great plan! I bet we are saving all the polar bears by crushing decent Xj's! /rant off

Billy any pics of how the half doors came out?
