My suggestion to use a ready-made diode (in the UK
I'd use something like
an OA81) is that you know that diode is good. You can then wind the coil
and wire up the rest of the set, knowing that if it doesn't work the
problem is not due to the fact you've not found a spot of the right
impurities in the crystal. When you've got it working, you can then swap
the diode for the crystal and catswhisker, knowing that if it doesn't
work the problem is with that.
That's cheating. What if you want to reproduce the experience of early
radio pioneers? They didn't have finely manufactured diodes :)
Otherwise there are too many variables IMHO.
And you'll be much the wiser when you do get it all figured out.
