well they are never "finished" always something getting bigger or better

but here she is:

 MG 9944

 MG 9953

NST 15kv 30MA
primary 1/4" 14 turns 1/2" spacing 10° dish
secondary 20.9" tall 4.3" dia
RF chokes and safety gap
thick wire for power routing
10 gap TCBOR type gap (with high volume barrel fan sucking though gaps) total gap of about 7-9mm
bottle cap (clear glass) 6 bottles 0.0065 uf, .7 bottles 0.0076uf (no visible corona)
lots o different toroids
RF ground 3 feet rod:

 MG 9959

 MG 9960

 MG 9962

 MG 9957

yeah its not the best looking but it does the job nicely

and in location with the RF chokes (you can just see the pipe i used for the safety gap at the end of the NST)

 MG 9956

the choke (has goo on it cause its recycled from a degauss coil)

 MG 9964

my "original" setup with bottle caps a total of about 0.007µf

 MG 9955

my new MMC, total of .008µf (from memory) (not 9µf as posted earlyer woops cry )

 MG 9967

it in location

 MG 9968

detail of the corona ring (made from a 4" end cap and washing machine hose)

 MG 9952

 MG 9951

and my top loads... including the one still in production

 MG 9946

 MG 9945

 MG 9948

 MG 9970

 MG 9969

the center of the next one is a 2 litres coke bottle.. the "hip" in the bottle holds the duct nicely and makes putting the tape on easy

 MG 9949

 MG 9950

still in production

 MG 9943

 MG 9942

and my variac. cost me about $10 (got it for free cause the brushes were stuffed one broken one worn off... use magna starter motor brushes cut em in half and then use a file to shape em have been working like a dream) 0-280V 8A

 MG 9954

I like the way you used recycled parts, nice to see someone else working on budget coils. 9µF tank cap!?! I assume you mean 0.9µF, your caps don't look that big to me. tongue
