Mas, both those nridhes were hot riveted.......

[masalai]

Now you have my attention, I am riveted, not being an ironworker - what is the difference? and the photo seems to me heads were 1.5"? dia? - - building a tank for WW1?

[Landlubber]

The big press is just that, red hot rivets were used and dollied by another worker, being red hot they can squash when whacked by a hammer.

Pressed rivets are done cold, hydraulics.

I assumed it was an early WWII motorized cannon destined for N. Africa.

Now I'm curious, maybe it's a between the wars project.

From teh quality of the photography I would imagine it is 1950´s even? I dont think they had the technology for such clarity @WW1 and possibly even WWII ?? The mens' fashion doesnt help much but seems more post-Glen Miller than pre.

It seems to be an Early M3 "LEE" tank built by a old American company known as Chrysler...

Keeping in the spirit of old riveted stuff, we are rebuilding one of the original WWII "Higgins" PT boats at the WWII museum in New Orleans. I find the design very advanced for its time. The structure used some aluminum plates and extrusions riveted as monocoque segments. These were integrated into the wooden hull, a very early use of aluminum in US patrol vessels. In the photos of our PT305 you can see the forward crew cabin area with deep web framing where you would crawl through a "lightning" hole to get in your bunk. Also, some of the aluminum riveted structure in the engine room.

is that built by Elco

[dccd]

No, PT 305 was built at Higgins shipyard in New Orleans with quite a bit difference between the Elco, and others. Total PT production was Elco built 345, Higgins 210, Huckins 18 and 4 built by the "Canadian Power Boat Company. Higgins is best known for the Landing craft and made the best performing PB's. Eisenhower famously credited Andrew Higgins with winning WWII due to his landing craft design and production, the LCVP used in all amphibious assaults. More than 20,000 Higgins LCVP's were built.

Yeah- I was struck by the clarity as well.

I got interested in rivets for some reason I can't quite remember & this photo was on the wiki page...

The bio:

"TITLE: Chrysler tank arsenal. Thousands of rivets are used in the production of one of the huge thirty-eight ton M-3 tanks. Whenever possible rivets are replaced by welded sections, but throughout much of the tank, as in the side plates on which this riveter is working, the steel plate is too heavy for welding. The riveting itself, a twenty-five ton
