This candelabrum looks like an unprepossessing block of wood when folded up, but opens out into an interesting array holding 9 tealights (or, with the means of some inserts, 9 regular candles). You can also make a version of this project out of a single piece of 2×4 lumber: see the last step.
The design evolved as I constructed it. I wanted it to be easy to make - just simple straight cuts on table saw and miter saw - but had a shape that was unusual and surprising and did not waste any material. The idea was to have a whole lot of nested L-shaped hinges that contained wells in each elbow. It required a series of cuts in a piece of wood of appropriate size, starting with a rip cut, then a cross cut at 2 degrees, another rip cut, a cross cut at 4 degrees, and so on. The pairs of pieces would then be glued together in L-shapes, holes drilled for the candles, and a dowel inserted to act as a hinge. I prototyped it in poplar (shown above) before making the final version in white oak.
