If you actually read whichever article you quoted the J2 thickness from then actually it is constructed from 0.3m thickness tubes not plate.
LULZ!!!
Walter 'Mainframes' Mitty brings the comedy gold again!
33 centimeter thick stainless steel tubes - LMFAO!!!
& how do you know what article I read anyhow?
Are you psychic now, as well as psychotic?
No; the article I read clearly said the tube walls were 0.3 millimetres thick, which is about right for lightweight steel tubing.
& if any of you Raown Derfers seriously think for one single second that steel tubing that thin could withstand the equivalent temperature of an oxy-acetylene cutting torch being played on it for 8 minutes solid, whilst only being cooled down internally by 250C at most, you are insane.
3500C minus 250C = 3250C.
ALL stainless steel melts at 1600C max.
3250C minus 1600C = 1650C.
So; that's 1650C you still need to dispose of... Care to explain how?
Of course, I'd just prefer you try the experiment I suggested; make sure you video it & leave instructions to someone who can post your fiery & explosive death on youtube mind...
We'll all enjoy that!
Toodle-pip, Losers; see you soon...
Until then;
Carry On Lying!
