Monsieur Shelf McFixitov

Depending on how quiet I can be I'll try to fix my shelf and store stuff on it. The metal crossmembers have long bulged out at the center, allowing the boards to bend and fall through. The idea is to drill holes and put a threaded rod with nuts on either side to keep the metal pieces from bowing outward when more weight is on the shelves. I've wanted to do this for years and finally bought the stuff to do it a couple weeks ago.
