I am currently doing this, which is horrible:
I tune to the approx frequency of the circuit in question, record F, solder the inductor on the test jig (deadbug FR4), then adjust the air variable capacitors until the scope shows lowest voltage trough. There are two air variable caps in parallel, one 380pF and one 20pF which are on a calibrated scale made using a capacitance meter in my UT61E. Then I plug this into my calculator and solve for L. I can get a reasonably accurate figure down to about a 50nH resolution which isn't bad for a pile of junk.
However this is incredibly time consuming and requires a large rig set up and I have a project which involves winding about 20 of them soon and I just don't fancy the job.
I came across a pile of cash and decided, hey I'll get one of those nice AADE meters that everyone seems to have. Nope, turns out the originator is unfortunately deceased and they are out of production.
Ergo, is there another method of doing this on the cheap, be it some Chinese product, a quick hack job or something that means I don't have to set this up every time? I've seen a few projects on the web which involve a PIC16F628 and some discretes which are possible but none of them seem to have been reproduced or verified in any way.
Ultimately I need to measure HF band toroids, preferably around the operating frequency to a reasonable level. I can trim out the rest worst case when peaking filters etc.
