Spotted this on pistonheads;

What's the deal with all the pop-rivets under the bonnet?

I think it's probably to induce failure by metal fatigue.

You seem/stitch weld a chassis to increase strength and rigidity over the manufacturers spot welds why would that not work?
Aircraft are held together with nothing more then rivets they seem to cope ok?

aircraft also have super strong epoxy glue, which is even stronger then the material they are bonding

not all aircraft?
I work on tornado f3 aircraft the airframe is constructed from aluminium ribs and stringers with an alloy skin over the top. Nothing more then rivets and a sealent to prevent corrosion holds it together, there is no glue.

Aircraft, glued or not, are designed to be riveted together, and its worked out and done properly, not by some idiot with a drill and a rivet gun.

The windows on the Comet were riveted on when they were supposed to be bonded. That ended well didn't it 
In all seriousness, every time you put a hole in a structure you're creating a stress raiser which will make it prone to fatigue. That's not the best thing to do on a major structural element of a chassis such as the suspension turrets.

Most commercial aircraft designed in the same era 60s-70s are constructed like this too. Military aircraft are subject to stresses and strains far greater then commercial aircraft and are built far stronger to cope with those requirements. There were no epoxy glues strong enough back then and there were no problems with structural failures etc.
Granted that skyline looks pretty shonky with all those tucker pops blasted in at random places but i believe the theory behind it is sound. Just because its not something that is seen as the norm doesn't make it a bad idea.
When you weld a chassis all you are doing is increasing the surface area of the joints in the panels to help reduce flex and give an increase in strength. Those rivets on the skyline whilst not a pretty solution will be doing a similar job imo.

What exactly do you think the rivets are doing there though?

I thought the problem with the windows on the comet was due to the shape not the installation method. Originally it was designed with square windows which led to stress raisers at the edges with subsequent well documented failures. The design later changed to oval windows to fix the problem be removing the stress raiser. It must have worked because the Nimrod is essentially a comet and up until recently was still flying.

I think the rivets will be holding the two parts of the chassis together stronger then the original spot welds would do increasing the rigidity just like a seam or stitch weld does.
However it looks better executed on the pics where you can see rows of rivets in the rear of the car on the actual seems of the chassis.
The rivets on the strut top wont be doing much i think he's gone a bit over the top there.
I'm open to discussion on this but i think it would work.
