Normally with a pair of pneumatic hammers, one each side! The rivets are
heated to red hot, then put in and hammered over. As the rivet cools, it
will pull the plates together. On smaller jobs, for example locomotive
boilers, a "Squeeze riveter" is used. This looks like a giant G-clamp, and
contains the rivet set and forming toll (often hydraulic) in one unit. We
used one of these to rebuild the boiler on a friends traction engine
recently.

particular
how on earth
they get them to also be watertight around the hole!
I normally can't think that hard on a Friday :-)
