Looking for a resource with personal experience with the components, assembly and installation of this specific fixture. I am in need of advice in shortening the vertical dimension of this chandelier so that it can be hung higher over my dining table. Manufacturer and Dealer support was not helpful; they seem to advise only from the fixture diagrams. Shortening the chains is straightforward but need to know if the center drop tube that houses the wiring to the lamp bases is detachable from both the upper canopy and the lower finial. Would need to cut and re-thread at least one of the ends. Manufacturer rep stated attachment at the canopy is likely welded.
