I use a pneumatic rivet gun. I bought it when I had problems doing 3/16" rivets with a hand tool. One has to be sure to keep one's fingers off the trigger until one is really ready to rivet. Operating the tool with a rivet only partially inserted means a very loose rivet that can be a mongrel to remove to redo it.

Hello All,

I remember seeing a documentary about the New York skyline during the construction of the Empire State Building and the rivet crews who built it. One of the team heated a rivet up and then while using the tongs threw the red hot rivet through the air where it was caught by the catcher who used a steel funnel to catch the rivet mid-air. The catcher then passed the rivet on to the hammer team - Accessed 19th June 2021 from New York Documentary - YouTube . I just watched a clip from a 1949 Glasgow shipyard where the catcher only uses gloves to catch the red-hot rivet as it is thrown towards him.

Here is a YouTube clip from a bloke who uses similar furnace heated rivets in a small industrial studio. Accessed 19th June 2021 from, Hot riveting process | Hydraulic riveting | Compilation - YouTube

Lionel,

Watch some of Fred Dibnah's videos where he was restoring traction engines, he was hot riveting in his backyard.

Interesting character, he was a steeplejack but he also demolished industrial chimneys the old fashioned way. Either laddered up, put a platform round the top and took them down brick by brick or he cut away half the base of the chimney, fitting wooden props as he went then set fire to the base to burn out the props.
Always had a Land Rover for getting to & from site. Early days it was a Lightweight, later a Series III shorty.

Turned up to Buckingham Palace to get his MBE in a traction engine. London traffic in a traction engine !
