Chris,
    You could use = sections of blue=20 foam used in the cannard cut in a long pipe or cynider = shape.  Cut=20 them up to make any type of pipe you want.  Coat the thing with = RTV, glass=20 over it.  Disolve the foam with solvent and pul the RTV out with = pliers. It=20 leaves a smooth surface inside the tubes.
