I believe that I've read that the distance from metallic objects
should, at a bare minimum, be at least 1/2 the coil diameter. So that
means 2 times minimum, giving 1/2 of coil diameter around the sides.
3 would be much better. Aluminum is good shielding material; onlt
thing better would be copper (or silver).


Guess I came up with a rather cheap alternative then.


Think newspaper, or any other kind of paper, would be good filling
material to isolate the transformer from the aluminum can?


Until it absorbs moisture.....

Well, you saw what someone wrote: "The various rules
of thumb you hear are just the result of someone determining what is
acceptable . . .". Put your creation together and see what "is acceptable". If'n it ain't, then get a bigger can.
