Everyone:
 Setting aside for the moment the ongoing discussion whether impregnated 
cardboard is better than glass for secondary forms, or whether Litz wire
is better than oxygen-free lark's vomit for primary conductors, I would 
like to draw everyone's attention to the following products offered in 
the current Lab Safety Supply catalog:

These drums are completely smooth inside and out, have no wax (ala
concrete
forms), and no metal rims (ala standard cardboard drums).  It seems to
me that
with a nice soaking in polyurethane, they (especially the third one
down) would
make _dandy_ secondary forms, and some of them would even make nice
magnifier
coil forms.  You'd likely not use the lid, although it too, could be put
into
service for a solenoid-shaped primary form for smaller coils.
