a while ago i made a truss type thing for a photo shoot i was experimenting with, my other hobby is photograpy. anyway, my photo lights all have stands, but i wanted to use clamplights for additional lighting. i built a frame out of 2x4 that is probably about 8 feet tall and 12 feet wide. it has three 2x4s extending across it to hang lights on. it stands on two homemade sawhorses. it is now sitting in my garage unused. my question: could i use this or some sort of cheap pipe from home depot to make my own truss or trees? my stage has horrible frontlight positions and i am looking for new and very cheap options. has anyone ever done this before? do you have any suggestions on how to build more truss?
