Well, FIrstly I imagine it'd be almost infinitely easier to get one for 20 
bucks or so than free. For free, you'd probably have to know someone who 
like hv; know someone who works ina  hospital; or know someone who works 
ina  junkyard. I advise visiting the junkyards in your area, particularly 
the ones which large companies dump their stuff at.
Something which strikes me as a possibility would be if you had a ute and a 
heap of friends, you could wait for a while until a hospital is getting 
redone somewhere, then ask them if you could take away an old xray machine 
they are throwing out. YOu'll actually be doing them a favour as these 
thinks must cost quite a bit for disposal.
This is the "go to the source of the waste" idea which works pretty well 
with finding junk.  A guy in sydney before he died a year or 2 ago, used to 
ring up companies with computers and tell them that he would take old 
computers off their hands free. So these large companies like sony and so 
drove up to his house regularly with enormous trucks and dumped old 
computers on his lawn I believe. THis saved the companies lots of money, 
and the guy swapped parts around in the computers, got them to work, and 
gave them to needy people.
If you are looking at getting an xray transformer; I think you should also 
look at getting a truck or a ute. It seems that you've gone up the power 
scale very quickly; from neon sign transformers to mots to xray 
transformers, etc. :) I don't see any reason why you should have to stop at 
xray transformers; in 6 months or so you might be wanting a substation 
transformer or something :) just kidding, but no doubt your desire for 
power will increase! Naturally, power will come with size and weight. Also, 
you'll find heavy stuff like xray transformers in even heavier stuff like 
xray machines. And you may not be able to dissassemble them fully in the 
junkyard. ( a petrol powered angle grinder may help) .  When I get a car, 
I'm thinking of getting a ute and bolting a 2 tonne hydraulic crane onto 
the back to load up junk :)

Good luck looking for junk! And don't hurt yourself :p well actually i hope 
you do hurt yourself. you always remember mistakes when they hurt you, and 
its so much better to be hurt by something than killed by it :) so yeah, 
don't get hurt without learning anything :)
