I need to design a 315MHz crystal oscillator. I'll go for
a Butler Oscillator with a crystal running at 105MHz then use a tank
circuit on the collector to get the 3rd harmonic thus achieving the
needed 315MHz. My problem is that I don't know the exact math I have
to use to calculate the component values of the oscillator. I know the
circuit model and the only thing I found online was general tips on
the design. I'd appreciate any advice on how to find out the exact values
I need for this circuit.

Hi!
See
pages 250-279 of Design of Crystal and Other Harmonic Oscillators by
Benjamin Parzen with Arthur Ballato.
It was published in 1983
by Wiley-Interscience, and is available by inter-library loan if your
library doesn't have it.
His 29 pages on a single oscillator
is pretty exhaustive and detailed.
Good Luck!
Fred
