There are numerous "web" sources of sphere and rod gaps (rods are 1/2" or 
5/8" square) breakdown voltages.

http://home.earthlink-dot-net/~jimlux/hv/rodgap.htm
http://home.earthlink-dot-net/~jimlux/hv/sphgap.htm for spheregap construction 
(there's a link to the table on that page, as well)

Needle gap is usually 3x the gap for the smallest sphere. The "needle" is a 
00 sewing needle.
