[cool][#0000ff]It is surprising how much structural strength can be added by filling a hollow space with foam. Once filled, any force applied to any area is equally spread over the entire length of the filled hollow. That reduces the potential for weakness at any particular location and the incidence of cracking or failure at a stress point. [/#0000ff]

[#0000ff]Other options would be wooden dowels or even substituting the PVC for copper or steel tubing.[/#0000ff]

[#0000ff]I plan to take some careful inside diameter measurements and go haunt the aisles of Home Depot and a couple of plumbing supply places. I'll bet there are some viable options once we know what is available.[/#0000ff]
