Next, is to add a small amount of adhesive around the outside, then flip it over and set it on top of the wood box.
Then I put some weight on top, to help hold the aluminum down, and give the adhesive a chance to cure.

Ok, after the failure with the screws above, I decided to use the structural adhesive, and re-test on the same 20" square box.
So, I sanded the edges of the aluminum, to remove the shine, and give it some "tooth" for the adhesive to grab onto.

And BAM. Fifteen seconds later, we have this failure.
As you can see, the screws remain in place, and the aluminum pulled through the screws.
I know, I know, what do you expect out of such thin aluminum?
Tomorrow, I plan on having a test of using another piece of aluminum from the same roll, but gluing it to the same frame.
I will be using the Norton speedgrip structural adhesive, that was shown in an earlier post.
We will see how that holds up, compared to the screws.

So, it's time to put some weight on this little puppy......
Putting the same 350 + lbs on the aluminum, that I put onto the blueboard insulation.
You can see the screw heads, all around the edge of the aluminum.

And then I screwed the aluminum to the wood frame. I used aluminum screws, and spaced them 4 1/2" apart.
The aluminum is about .010" thick. That is 10/1000 of an inch thick. Not very thick by any means.
You can see the white heads of the screws in this pic.

Ok, next is a test of the strength of aluminum, which is screwed to plywood. I wanted to see how it would hold up to weight being put on it.
So, I looked at the side of the motor home, and found that the rivets that hold the bottom of the siding onto the motor home were about 4 1/4 inches apart.

Ok, back on topic.
Here is an adhesive that my cousin turned me on to. This stuff will bond almost anything together. I have used it for various projects, including some plastics, wood, steel, and aluminum, with excellent results.
He uses it in a body shop, and while this has only 1 minute open time, (yup, gotta work fast), there are other version of this that have longer open times.
The reason for posting this? I am going to use some of this on my rebuild. Pictures will be coming, although, not sure it will be tonight.
I have no affiliation with this outfit, but I am definitely a satisfied customer. Be warned, it is not cheap...
