Would it be possible (and relatively safe) to use two neon sign transformers to add to the voltage of a fusor?
Currently, I have a 15,000v, 30ma and 60hz single phase neon sign transformer. The inputs would be wired in a parallel and connected to a variac and the outputs would be wired in series. Would this be safe to the cores of the NSTs and other components?
Just an idea
Using two NSTs..?

John,
You cannot series connect two NSTs for higher voltage because most of them have the center tap of their high voltage winding connected to ground. You can parallel them for more current, but this is rarely necessary in Fusor applications.
The best you can get out of a non-GFCI NST is 0.707 x the nameplate voltage, using a diode half bridge. To get higher voltages, you would have to use a voltage multiplier, but this gets you into expensive HV caps and dangerous stored charge.
