OK -- so I have 8 arches made from 1/2" electrical conduit and they are GREAT. They stand up on their own w/o any bracing.
I'm making a new object (yet to be revieled, but I think it is going to be very cool) that I need 8 arches for. This year I'm putting 8 segments of 70 Ct LED C6's with 2 colors AND -- it is TOO heavy, so the arches are VERY unstable. I tested it last night. BEFORE I wrap 16 strings onto 3/4" electrical conduit and retest <sigh>, has anyone done this before and were they stable??
