锘? Industrial Pipe Bookshelf and Shoe Rack This industrial pipe shelf is the perfect project for any handy or non handy person looking to update their room. Screw the 5" threaded pipe into the flange. It looks good, but depends on balancing stuff on the pipe. Bumping the bottom book will likely bring the whole shebang down and getting, for instance the fourth book down from a pile of seven will be difficult and require three hands.Building it with two courses in parallel would be better but would also dramatically increase the price, by doubling the materials costs.(basically build two of these and replace the vertical sections between elbows with a T linking the two together.)Bio:I graduated from Union College with a BS in computer science and visual arts and a minor in math.
