Since your voltage is so low, I would definitely consider going to a
4 inch dia coil as inductance goes up as square of the radius of the
coil and inductance x rate change of current (dI/dt) is what produces voltage.

hello, i am going to be building a tesla coil modled after one on
the internet that's a 4kv 4800pf primary 11 turns of 1/4 inch
coper secondary 1000 turns of 30 AWG with a pvc diameter of 2.5
inches. i was wondering how do you get these numbers. like how do
you know how wide the coil has to be. or the turn ratio, or how do
you find the frequency of the coil so you can determine the value
of the capacitor you need. any calculations that you guys know to
solve for these things would be very helpful. i would like to get
to the point where i can make a coil totaly on my own. thanks
agian for all the help
