Hi, welcome to the list. The first suggestion is on secondary. if you get
hold of a pool/spa installer/plumber they surely will have some 3 1/4 inch
od white pvc 24 inches long is enough. second
suggestion is build the primary with 1/4 or 3/8 tube,  i use salvaged copper
wire, 1/8 square or larger also works. wind 18 inches of #28 wire for the
secondary. primary wants at least 12 turns or more.
now with an oilburner transformer and a good mmc, and something for a
toriod, you should be able to get up to 20 inch arcs. for torois i use a fan
shroud, the thinner ones with rounded surface at the edge will get you
started.
My coil this size is running 550 watts from a 9 kv 60 ma transformer, i have
hit 42 inches using the coils described. you can use this coil set up to a
1000 watts easily. one of my young friends has this coil set, runs a pair of
bug killer transformers and gets 14 inches of arc. probably only 200
watts...
Also find the Tesla Coil books written by many on this list.
