if you want a legal keg see craftbrewer, just tell him you want a SS one like a euro A type sankey etc (no rubber coated etc)
http://www.craftbrewer.com.au/shop/details.asp?PID=3714you might score one at a scrap dealer, they often tell you they have "none" on the phone but if you walk in with $50 they might just have one.....
make sure it has not had something weird in it... best if they smell like old beer ..
you could stir the one with sugar on the bottom, not ideal but should be fine
dont splash the wash just get a good whirlpool going, if enough ALC and yeast is already happily working it should not get infected using a clean spoon.
you can "strip" using any still really...
just run it once then run it again
you might loose some product this way but normally helps clean it up before the need to carbon.
i dont carbon but i make pretty heavy cuts and throw away plenty, but once you build stocks that's easier to do
i would do something like this
run 20L wash get 5L of 40%
run another 20L get 5 L of 40%
add say 5L water and rerun the 10L maybe getting a good 8L of "hearts" of which 4L would be my best hearts for gin or vodka and 4L in the whiskey jar
