How are these rivets kept ´red hot´ for this operation?
Actually the rivets were heated on site as needed, in the early days they would have used small 17" diameter coal forges in more modern times they would have started using cylindrically shaped propane forges much like several knife makers use . Even more modern way of heating rivets on site is by induction coils. Induction coils can heat as rivet in seconds simply by passing the rivet through the high energy field.
Never try to tell me it can't be done

There is a furnace on the ground. A guy take one out of the furnace, tosses it up to a guy who catches it, then hands it off to a guy that puts in into the hole, then a guy hits it with a big hammer, while another guy hold a block behind the head. Seriously...

See the well-dressed rivet-tosser in the right side of the pic holding a pair of tongs.
thaTS A LOT OF RIVITS. possiably they could of used better steel and a few less rivits.
Why? That would have meant less work, and the bridge was built to create jobs and help economic recovery.
p.s. you mis-spelt rivets.
and you misspelled ´misspelled´ as ´mis-spelt´. no bfd.
not less work, just move onto another project. Im sorry I spelt riviots rong...but aparently you could tell what I was refering two.
The Sydney Harbour Bridge was built in an attempt to fight the depression in Australia during the early 30’s, so there was no other work to go to. It employed tens of thousands of people, at many different levels. It was, to some extent, a success as it put money into the economy. The government we have now would never even think about doing such a thing.
p.s. don’t let your spelling bother you, I’m just a finicky bastard raised by finicky parents!
