Welcome to the list! Starting small is a good idea. Cheaper and you can
get a good feel for things.
Do you have any construction sites that you can hang around? That's the
best place for materials. I'd get a PVC pipe if you can or if not,
something a bit thicker. Perhaps a cylindrical pitcher or something from
Target. I think you'd be better off with something a bit on the thicker
side just to provide a firmer surface to avoid getting 50% done only to
accidentally crush the thing or to have it crush and shed all the turns
you have so lovingly put on it.
You can also find small sections of copper pipe as well as hunks of wood
for mounting your project on.
I have found that if I go to electric motor shops I can often get the
tail end of a roll of wire and not have to pay winding costs to have it
put on a spool.
You can use beer bottles for capacitors as well. I haven't done that
myself, but it's a cheap way of making capacitors.
Hope that can get you started.
