How does that explain oxygen fires at hospitals, or the Apollo spacecraft accident?

its doesnt explode but it accelerates a fire. Just like when you blow on an open fire.

No oxygen - no fire, no matter how much fuel you introduce, add more oxygen and you get a bigger bang. Afterall fire is ust oxidation of the combustable material.

Holy Cow, now you tell me. We used to muck around with acetylene when kids, with our chemistry sets - calcium carbide & water. And also asbestos. Probably lucky to be alive

Pure oxygen can cause some fuels to spontaneously combust. Back in 5th form chemistry we were shown what a jet of oxygen on a newspaper would do - pretty spectacular

Matt, any chance of a pic/drawing? I didn't get that description....

MIG/MAG (pistol trigger-gas-arc-continous coil of filler wire)was primarily developed during WW2 for the ease of application of a filler material to join two parent materials,
During war-time, majority of the blokes were fighting whilce a very large contingent of female voluteers were tasked with building aircraft, vehicles and arms.
It was developed to speed production as well as to assist "a less skilled" cross section of society in the fabrication of steel/aluminium structures.

As I remember it, being to taught to me during my Polytech days.......

Strictly speaking it doesn't have to be oxygen, there are other oxidisers that will support combustion in the absence of oxygen, chlorine, nitrous oxide etc.

This what you mean Matt - but not full welds around the tops of the towers?

Ditto

Am interested in the bracing for the towers and the diagonal bracing also, any chance of a pic or modifying the pic posted by Wombat??

I've thought of welding a piece of box section inside the front crossmember 1x1 inch (and also the same on the rear frame 2x2 inch). Would this give these areas enough strength to become jack points?

This pic gives the idea but they would span the whole length, left to right.

you know that nitrous oxide contains 33% oxygen? with heat it will break up into 2 nitrogen and 1 oxygen part, thats why you can use it to burn more fuel in an engine.
