One of the little known facts about the Sydney Harbour Bridge construction. It was built from the buttress' at each end to a central point where the 2 halves were to be joined. The halves were cantilevered from cables, which during the process of joining the 2 halves were slowly slackened to allow the bridge to droop down and make the connection. However as this process was started in the afternoon the contraction of the cooling cables and bridge steelwork was faster than the cable tension could be released. Work was stopped once the engineers realised they were chasing their tails, and recommenced the following morning to make use of the heat expansion.

Australia is experiencing a recession right now, but it is masked by the ‘rona crisis.

Not to turn things into a political conflab but every 2 or 4 years the Politian's in the USA loose their collective minds if in fact they ever had a mind in the first place. this disrupts countries around the world some are effected more than others. there is an old saying that when America sneezes the whole world catches a cold. This political season is setting up to be the worst in the history of the planet all stops have been removed and the extreme radical facet is attempting to lobotomize the entire planet.
what is going on or what they are trying to feed everyone intravenously will be much more dangerous to the 7.8 billion souls on this planet than has ever been thought of I dare say a descriptive adjective for it may not even exist yet communism socialism Marxism what ever people have know or been subject to in the past and present are mere pin pricks of what may come to pass.
I apologize for my statement not having a single thing to do with our goals of providing useful information pertaining to HMT.net but I felt it needed saying and this post along with a few previous should be removed to quarantine or placed in a not so funny farm forum away from anything having to do with tools

I don't suspect that will fit in my .177 Weatherby

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.

Riggers riveting the red-hot rivets on the lower outside south chord, Sydney Harbour Bridge, 1930-1931 / Sam Hood.

How are these rivets kept ´red hot´ for this operation?
