Making the rods was the tricky part. I used a piece of angle iron, drilled the diameter hole I wanted the rods to be then followed over the top with to larger drill bits. Don't drill all the way through with the last two bits, make a step. Then I cut my material down to about 1/4 in or smaller, round off one of the ends, place the larger end into a drill and then run the material through the angle iron. I would cut off rods after you have around two inches of length. Any more questions let me know.
