Light stand with Flexible clamps for positioning reflector panels:

I made 4 sets of flexible clamps:
box of 18 spring clamps purchased at Menards for $10, ~5 foot length of heavy gauge electrical wire, carton of 3/4" hose clamps to secure wire to the spring clamps.
I used different size clamps on each end of wire, so that I could clamp to a wide variety of objects or pipe diameters.

I made moving stand from old chair base and 3/4 inch pipe. I wrapped base of pipe with electrical tape until it fit snugly in chair base.
Adding fittings to end of pipe allows additional length or horizontal bars to be added.
