I made a storage unit out of available stuff on the ranch. I was frustrated with warping jump poles and panels, so my necessity mother of invention side took over. I took eight full sized cinder blocks, the kind with two hollow openings and used liquid nails to glue two together in this fashion: One cinder block standing on top of another on the short end, the second top one turned half way around, and glued together on the center short ends. I spread them apart, long enough for pole storage, one stack on each corner. I used a long broken/cracked/warped pole slid through the lower block’s top hole on each long side. I cut up another broken/cracked/warped pole to fit through the sides that would be the short side of the storage unit. So two long used poles, one each for the long side and one cut up for the short sides, installed in the lower hole of the upper block. You have made a rectangle and once assembled, you can store about 10-15 poles or planks on it. The poles are resting on the higher short pole ends of the unit. I made two, keep them and the stacked poles in the arena on the side next to the arena fencing. One double cinder block did come unglued in the time I have been using this. Maybe Gorilla Glue would be better - don’t know. Also thought maybe you could add a third support set of cinder blocks & short cut pole in the center to add more support if necessary. It wouldn’t be too expensive if you had to buy the cinder blocks.
