how to make air inductor?

can someone plz tell me the simplest way to make air inductors with a known inductance of 80nH (or 0.08uH) using copper wire(wire diameter=0.55mm).it wud b really helpful if u cud also tell me which formula to use to make this air coil inductor.is it by using Wheeler's formula?btw,can i use a drill bit to wound the coils?its the only thing i can think of using since I'll know wut the coil diameter wud be(5.5mm).need some advice..thxs!

Here is the online calculator: http://www.pronine.ca/multind.htm

The Multilayer Air Core Inductance formula is:
L {uH} = (31.6 * N^2 * r1^2)/[6*r1 + 9*L + 10*(r2-r1)]

L{uH} = Inductance in microHenries
N^2 = Total Number of turns on coil Squared
r1 = Radius of the inside of the coil {meters}
r2 = Radius of the outside of the coil {meters}
L = Length of the coil {meters}

to AVIANO--> thx! some very useful info..
to Awarapunshee -->nice calculator..correct me if i'm wrong,but thats only for multi layer coils rite?is there a calculator like that for single layer coils?

You can find alot of calculator on the web, one is here
