Farnsworth fusor is a nice little side experiment but won't yield net positive fusion power, don't even waste your time there. You'll find 15k isn't nearly enough to get a decent system to experiment with fusion, let alone lab quality anyway. Vacuum levels that high are a nightmare, you need to heat the metal to pretty high temperatures just to degas it, and use materials which wouldn't off-gas and ruin your vacuum levels. Let alone have a system which will allow room for a polywell (going from memory here) ? several meters in radius, with cooled coils and enormous levels of capacitance and maybe a power source in the megawatts just to hope to gain net power as theorized by Bussard. An experiment like is MUCH too insurmountable for one single person unless your blind rich. The power factor correction capacitors alone must cost triple that price.
