I hope this isn't too much to ask, but do u know how the main center structure (on which the plywood is wrapped) is put together? I'm especially interested because it clearly needs the strength to safely hold a tv. My wife would love a setup like this but we don't really have the money for a contractor. I'm fairly handy and know many others much more so than myself. I'm sure we could tackle it if we knew how to go about it. I know this is a lot so I thank you very much for any help you offer.
