Our cable spool duck house (http://www.instructables.com/id/Cable-Spool-Duck-House/) was so much fun that I decided to keep going and build another "tier," which would serve as storage for duck-related items, as well as a bench where one might sit and read aloud to ducks, were one so inclined.
Step 1: Materials
Two of these half-round bench/cabinets can be made with one four-foot cable spool (if you throw in a few additional pieces of wood). Some hinges and a latch and/or handle are required if one expects the door to behave in a door-like fashion.
Galvanized wood screws holed it all together.
Step 2: Bisecting the circle
Cable spools have heavy-duty metal rings at their hub. These are placed there using advanced space-bending technologies which defy the laws of physics. That might not be entirely correct, I'm just making assumptions because I can't figure out how the heck the magical spool-building elves do it.
In any case, since I wasn't able to teleport the hub out, I ended up cutting right up to the hub using a circular saw. And a hand saw. And a screwdriver and a hammer.
Instructables user Hoopajoo (who may or may not be a spool-building elf) provided the following tip via the comments on this 'ible:
"The easiest way I've found to dispense with the hub bushing is to place a mechanic's socket of equal size to the bushing and, using a wooden or rubber mallet, drive it through. It can be easily recovered once you cut and remove the top. If such a socket is not available, you can substitute a wooden dowel or board of equal dimensions and use a metal mallet in lieu of the wooden / rubber one."
