Cover the tube with paper mache -- then leave a small inner "access panel"
from which to puncture and remove the inner tube. Cover with alum. foil
and cheap toroid ---viola! One teacher I know made a 5 ft dia HV oblate
for a big Van de Graaff he built using paper mache and some winter help
from a school art class. Output was over 1.5 MEV with sparks nearly 5 1/2
feet long!
