Wrap it well in bubble wrap or similar....

Whack in a few handfuls of limestone aggregate (won't make a spark)....

Wedge into a small concrete/mortar mixer & run until cleaned out

Diluted brick/patio cleaner cleaner or diluted battery acid swill around until rust gone, wash out with lots of tap water, then rinse with de-ionised water dry out as quick as possible, fill with petrol and keep it full year round, Simpler.

Thats my method too but i use Phosphoric acid instead, stuff called PH Down (on ebay) as it leaves a film over the metal preventing further rusting. Well i was told thats what it does & it seems to be true.

I used this on my J tank. Did a great job, but I did get the heavy rust off first using limestone pebbles and shaking the tank for hours.

Any time you use water or a water based solution it's best to use boiling water. That way when you come to tip it out the heat imparted into the steel helps dry out the residual moisture quicker.

VERY CAREFULLY grind the base of the tank from the top.

Once you get it split, you can clean and grind the inside of the tank and base with no obstruction at all.

Once you are happy with the finish, simply weld the seem together again.

If you are very lucky you might get away with touching up the bottom of the tank with a little brush with some Humbrol enamel.

Glad to be of some assistance.

and from todays BBC 7 day quiz,
CORRECT! It's aluminium foil. A cheap way to remove rust from steel is to rub it with aluminium foil dipped in water

The Aluminium oxides and the rust reduces to iron.

They use rust and fine aluminum powder to weld railway lines together.
The rust turns to liquid iron joining the ends together !

So try dangling some bacofoil in your tank.
