Screw the #23 black iron upright into the base. Slide PVC assembly A7 over #23. Screw iron cross #34 into place. Along with pipes #24 and #25 and elbow #35. Get everything tightened up. At this point you should have two pillars of iron pipe with a PVC covering. Turn the pipes until the ends of the two columns are close to one another. Install the union #36 and tighten everything up. You should be able to figure out the rest from there.
