I used a slab of 10mm plate for a frame I built a couple of years back: about 1000 x 600mm, it may have been flat when it was delivered but it was anything but by the time I'd finished torturing it!
The thing had to be strong as it was (and still is) holding up (literally) a tonne of lead...
Those walls are two inches thick. Each slab weighs 140+Kg. Note cunning use of box section for 'feet' which allows a pallet truck to be used to move the monster (there are holes for the truck wheels in the bottom). We installed it (nine floors up in a hospital) without issues but when the place was refurbished last year we had to move it to another building. As we rounded a corner in a corridor there was a loud crunch as the pallet truck wheels broke through the Bison beam floor slab.
Once we'd levered it out and got it out of the building, we decided to point out to the structural engineers of the new building what we were up to; they did a quick calculation and discovered that the load on the truck wheels worked out at 13 tonnes per square inch. Unfortunately the floor at the new location (Bison beams again) was only rated for 9 tonnes/ square inch, prompting a rethink on where we could put it...
Access into the thing is by the vertically-slid front door; it drops down on a seesaw arm (seen here from the back):
The pic above shows the electric ram that pushes down on the seesaw to close the door... which weighs 90Kg. The wooden chocks (in the second picture from top) were replaced by huge rubber buffers in case the door ram fails and the thing comes crashing down.
The main chamber is topped by another with walls of a paltry 10mm thick lead
The top chamber houses a 320kV x-ray head (weighing another 40Kg) firing down into the main chamber, where if it were physically possible for you to spend 5 minutes, you would spend the next few days - maybe weeks - dying a very nasty death.
Incidentally the stainless liner was beyond my capabilities to fabricate; it was created for me by 'Stainless' Steve Charlesworth of Huddersfield, whose main claim to fame was that he created a stainless sculpture of King Oswy for a public building in the Isle of Man. Apart from that he also once owned a fearsome beast of a TVR and now runs a pub, but I digress
Errr... sorry, got a bit carried away there with my 10mm plate. Maybe this should be in another thread entitled 'Fings wot I has made, and that'...
