What did you do in the shed or garage today

[Skylarking]

When I was a boy our neighbour was an engineer at Rapid Bay mine. He was a brilliant welder using arc. He used to weld stuff for me when I needed it. Chip away the slag and a perfect weld every time.

There are some really skilful people about bu5 they are getting thinner on the ground as time rolls by.

The welding story/myth I like is that Musk found and recovered the Saturn V rocket motors from the bottom of the ocean. He then got his experts to attempt to copy the engine design but they just couldn’t weld the complex rocket nozzles. They couldn’t replicate those welds without getting cracks and other defects. So he got his experts to design a 3d metal printing machine that could make the nozzles.

Who knows what the truth is behind the story/myth but the only article I found about the Saturn V rocket engine recovery was by Bezos which is now on show at the Smithsonian

Saturn V rocket engines recovered from seabed

Rocket engines that sent astronauts to the moon have been recovered from the Atlantic in a Jeff Bezos-funded expedition

Apollo 11 rocket engines that put man on the moon discovered at bottom of the Atlantic and confirmed a day before the 44th anniversary of Armstrong's first steps

First recovered in March, experts have now confirmed the rocket engines recovered from three miles below the ocean surface are Saturn V first stage F-1’s used by the rocket that put the first men on the moon

Maybe megalomaniac Musk has hijacked Bezos’ story, which is more likely than my memory falling

One of the welding guys I used to work with would often have his work showcased on "Weldporn".
Playing for colours, different styles, youde think some were machine welded and so many other things.

Definitely an Art form.
All about knowing your machine, it's settings and what different materials can cope with.

Probably going to look at doing another bike frame soon, will get a mate to weld it, because the material of one of the cromo tubes is only 29 thou thick.
