You should try to find a pair of these little cone wrenches...

Once set, you lock the cone against the retaining nut and it's almost impossible to do
without at least one of these (or something similar/thin).
The hub is set when
-minimum play at hub
-little or no rotation of crank when back wheel spinning
-Spinning crank= too tight
Shift through all gears and observe.
Crank may spin briefly but should stop/settle down.
Also chain should not be tight either, it also needs a little play..
Sounds complicated but you'll get the hang of it.
