I found some inexpensive fiberglass tent poles for $3/each. The problem was that they were too short at 28". For this size of softbox, you will need four poles that are each 36" - 36.5". I used the shorter ones, cut them with the dremel to size, then used epoxy to glue them together. I used small 1.5" pieces to 'plug' the ends of the metal sleeves - again with more epoxy. I notched the ends with the dremel so that the epoxy would have something to grab.
