Making small HV capacitors

Is it difficult to make small HV capacitors like .001uf 5KV? I'm
thinking that aluminum foil could be used but what could be used for
the insulator?

Try 10 0.01microfarad, 500V (or higher V) capacitors- with end connections-

not side by side- connect in series and put in a glass or plastic tube. Even
better use 100 0.1microfarad, 50 v or higher rating. You can use foil (or
better- a metal coating) on either side of a glass or clear plastic sheet
or tube (dimensions larger than foil to prevent flashover at edges. If
plates used, use two with outside grounds (joined)and layer between being
hot. It will be bulky.
