For the broadcast AM band, a toilet paper tube wrapped with fine wire stripped from whatever is handy works well for a coil. Make a shunt for tuning.

For caps/condesers, rolled strips of newspaper or wax paper with aluminum foil strips cut narrower work well.

Of course it works best if you understand the principles behind those things.

Ground is most important on a xtal radio. Antennas and patience help tune signals.
