"you need a spark gap - two nails and a piece of wood will work" 

IF you want to start a fire or electrocute someone! Wood is conductive at TC primary voltages (10-15 kV). Two nails driven into a piece of wood and attached to an NST secondary can carbon track and smolder or flame within minutes. IMO, NOT a smart move.

Use only good insulators like PVC with plenty of air flow.

Eric - most of us start small - you don't' need donations, and you don't need more stuff. 
 
you need wire - $5 or so will get you the wire you need from a surplus place, or unwind a transformer or other coil and get it free. 
 
you need a spark gap - two nails and a piece of wood will work (not as well as fancier stuff, but it will work) 
 
you need a cap - beer bottles (or milk bottles) with brine will work 
 
you need wire for a primary - scrounge some old electrical wire - whatever you can find 
 
for a first toy though, make jacob's ladders - all you need are 2 coat hangers and your neon sign xformer 
 
start with the small stuff, ask questions about that, then consider bigger
