This is my new bookshelf.
Almost. It needs a bit more work. I stopped here last night because the top shelf that you see needs to have an inch shaved off the right side since the wall is uneven. Then the pipe will go through the holes correctly. There will be one more shelf above that.
The bottom three shelves are 14" deep 128" long. The rest are 7" x 96". I had to extend the lower three to make them work the way I wanted. I used a good strong glue on the ends and a reinforcing rod hidden underneath.
Once they're assembled I'll still need to sand the ends of the boards to get rid of the burn marks from the saw. The pipes need to be painted black. And I'll need to touch up the walls where I've scarred them up assembling the shelves. And, of course, screw everything down.
Notice the weird bit of pipe out of the support to the right of the laptop. That's going to be a reading light before I'm done.
Before putting the shelves up, I put the pipes together to triple check that they'd fit. I brought Gandolf in to see my work. She hadn't seen the room since before the mudding was finished. Her reaction was pure surprise. It was a whole new room. She looked at the pipes standing on top of the assembled 14" shelves and asked hopefully, "perches?" I'll have to get her somewhere to hang out in this room, but I don't dare leave her in here. The books would prove too much temptation to chew on.
