Chris,

Surely you can scrounge a piece of PVC water pipe in your area.  Recommend
you start with a 4 inch diameter PVC pipe - low pressure (thinwall) type.
Your cardboard forms will prove to be flimsy and dissappointing in the long
run.

Secondly, plan on winding about 1200 turns of 25 to 28 gauge solid enamel
coated wire, which you can get from your local electric motor rewinding
shop.  This will set the length of your form.  Get the wire, and wind turns
on a pencil and measure how many turns occupy one inch, then you can figure
how long your form needs to be, of course adding more length for the top and
bottom.

This 4 inch form will work just fine for a tiny power supply, and will save
you building another coil when you are ready to increase power.  Eventually
you can get at least 3 foot streamers from it.  You can start out with a
rather largish toroid on top with a breakout point (e.g. a thumbtack
pointing outwards).  Later, with more power, you can remove the breakout
point.

Enjoy, and please realize this hobby is rather addicting and will lead you
to many years of fun experimentation along with some cost to keep buying
more stuff.
