[quote=catdan]We've used a stainless steel tube with an OD of 3/4, filled 2" on both ends with polyester, then slid a clear hose over it. On the end with the hole, we drilled the hole oversize and inserted a bushing.
Depending of wall thickness of the available SS tube, it's pretty light yet stiff enough.
