Jesse, 
    Why not just multiply pi times the diameter (divide by 12 to get feet 
per turn) and then multiply that by the number of turns you want?   I would 
guess that you plan to use 24g wire if available for your first coil.   If 
so, you get approx 47 turns per inch(I just measured some 24g and found it's 
diameter to be .021 " giving 47.6 tpi) depending, of course on the enamel 
coating thickness.    
    Hope that's enough to help you.  I don't have any sites bookmarked that 
have wire tables.
