Re: [TCML] Primary Support Materials

I'll second that motion.  I've been using PVC pipe and zip ties for my primary supports since the 1990's.  I've never noticed any particular propensity for PVC to break down and carbon track--not any worse than any other plastic.  This is the quickest, cheapest way for the non-machinist to build a primary support.  If you require an appearance-grade coil, do something else.  The PVC pipe method isn't pretty.
