does anyone know where i can get any of the below materials for cheaper than normal???? Answered

-A vacuum chamber, preferably in a spherical shape
-A roughing vacuum pump capable of reaching at least 75 microns vacuum
-A secondary high vacuum pump, either a turbo pump or oil diffusion pump
-A high voltage supply, preferably capable of at least 40kv 10ma - Must be negative polarity
-A high voltage divider probe for use with a digital multimeter
-A thermocouple or baratron (of appropriate scale) vacuum gauge
-A neutron radiation detector, either a proportional He-3 or BF3 tube with counting instrumentation, or a bubble dosimeter
-A Geiger counter, preferably a scintillator type, for x-ray detection and safety
-Deuterium gas 
-A large ballast resistor in the range of 50-100k and at least a foot long
-A camera and TV display for viewing 
-Lead shielding


Building a fusor ?

None of this is "cheap" there are plenty of surplus sources out there, its knowing where they are You don't say where you are, so its hard to offer suggestions. My sources in the UK won't be a lot of use to you in India, say.

Chicagoland, so i don't think so either, but thanks for the comment.

I saw somewhere you can make a vacuum pump out of an old refrigerator compressor

I can definitely tell you're building a fusor :).

Cheap, huh?  You must be making a little joke there, or using that word in a way I don't understand.

Anyway, you've seen this one,

If anyone here actually knows where to obtain all that stuff, at any price, it would probably be Christensent , the author of the fusion reactor 'ible I just linked to above.

Seems like there was someone else here who actually built an oil diffusion pump, um... here:

Regarding lead, if you happen to have a "recycling center" near where you live, you know a place where people take their trash,  they might have section devoted to  dead batteries.  This pile of dead batteries may include a few of the lead-acid variety, and hopefully this pile will not be guarded too closely.  That way you can slip a few old car batteries into your pockets, provided you have some really baggy pants.

Well, I'm joking about the baggy pants, but not about stealing, erm... I mean liberating a few old car batteries.  A large part of their mass is elemental lead, and that part will just melt if you get it hot enough, with no smelting required.

wont melting lead/acid batteries cause them to explode and emit toxic gas, or is that only with the alkaline and lith-ion types?

I am glad you asked for some clarification about this.

What I had in mind was melting down the lead plates and connector pieces, taken from such a battery.

In order to get to these plates and connector pieces, some other steps are necessary. These include:  draining the acid electrolyte from the battery, cutting into the plastic armor that surrounds the car battery,  removing the plates, and also removing stuff that is not made of lead like plastic/paper/fiberglass separators.

BTW, these plates are covered with lead oxide and lead sulfate, but I think that part will just come loose as slag when the plates are melted, and that it will be possible to just pour off the molten lead.

Yes, lead sulfate and lead oxide are toxic, but I think they like being solid, and for that reason only small amounts of these will be present in the vapors that come off from the crucible.

Actually, this idea of salvaging lead from car batteries might be a little more complicated than I made it sound.  So I apologize for the handwaving.

i didn't mean "cheap" per SE but for a lower price than I've seen in the usual places i'd look for stuff. i can spend some, i just don't have an exorbiant amount to spend. thanks for the links and ill definitely have to check out the diffusion pump.
