For all  of you guys that make the big secondary tubes (I suppose big would
mean  bigger than 1 foot in diameter?)  Do you use PVC, or do you have  some
clever scheme for making them out of other materials, like fiberglass  or
something like  that?

Hi Tim,
 
    There have been many different solutions tried from  fiberglass tanks to 
stacked plastic barrels, to polyurethaned cardboard concrete  forms, to coated 
wooden struts, to custom manufactured forms, all with  reasonable success. 
The limits are: what's available in your region, what can  you afford, and how 
inventive are you?
