"[FONT=Arial, Helvetica, sans-serif]Polyvinyl chloride (PVC) is unique in its high chlorine and additives content, which makes it an environmental poison throughout its life cycle. Vinyl chloride is a known human carcinogen. PVC releases dioxin and other persistent organic pollutants during its manufacture and disposal and cannot be readily recycled due to it chlorine and additive content. Furthermore, additives are not bound to the plastic and leach out."
I said this on another forum, but I'll reiterate here. Hanging a light 7ft in the air on several pieces of uncemented 3/4" PVC is an accident waiting to happen.
Yeah, I don't know about hanging lights at the top of something like that, but a bag full of those parts would end up being useful, even if only for the "This way to set" sign. That DIY silk, though kind of small. gives food for thought. I may spend an afternoon and put together a kit like that. I bet it will become that, "Damn, I'm glade I brought that stuff" item in the future.
I think for not heavy lights that aren't going up too high this could work. But unless you make it adjustable, your sort of stuck at a hight level or at least stuck without wasting time changing it around.
Thanks for the input, guys. I realize that going to the max of 7 feet can be risky, which is why you always stabilize and practice caution, just like with pro gear. When I shoot stuff on my kitchen table I've got two 500 watt worklights at 6 feet (on separate stands) bouncing off my ceiling and they only wobble a little.
I hope it is obvious that this is for small sets and setups, not a place to put an HMI. These have come in very handy for me many times and might for someone else.
