Large secondary forms

["Robin Copini" <rcopini-at-xxxxxxxxxxxxx> (by way of Terry Fritz <twftesla-at-xxxxxxxxxx>)]

Hi All,

 The recent discussion concerning sonotubes for forms and their
suitability hints at a larger problem, that is finding suitable large
diameter forms for secondaries. At most Mcdonalds outlets here in Oz,
there is attached to the sides of these buildings large play apparatus
for kids. The great bulk of these resemble the inner intestinal workings
of some mythical beast, i.e. very large diameter TUBES! Has anyone tried
these tubes as a sec former?, are they suitable? I would like to know as
I can get access to these tubes quite easily down here.

Best Regards

 Robin Copini.
