I need to wind 180nH inductor for a parallel tuned circuit I'm
building,

Paul-

I suggest you find some stiff wire, wind about five turns using a pencil as a
form, and stretch or compress it to tune the circuit.

If you want a more stable inductor, then wind it on a high value, one or two
watt resistor. Once the desired inductance is set, put some kind of varnish
(coil dope) on it to hold the winding in place.
