The following pictures show how I made the hinged obelisk.

I started with a plan for a shelf size where the obelisk was to be cut in half so it would be big enough for the 1 1/4” hole for the candle and the two brass pins. It was supposed to be 2” square which meant about a 4×4x8 block. the wood was so chewed up by ants that the biggest block I could get was 3 5/8” square x 8”. I laid out the cut lines and that left a shelf size of 1 7/8” square which was going to have to do.

I made the first cut on the back:
I leveled the surface on the jointer and then set it up level in the mill and cut the hinge pocket:

then I cut it in half at the designated level:

I used the scrap from the first cut to cut out the hinge pieces:

I sawed it into a hinge on the scroll saw:

Then I split the hinge so I could put in blind holes into the sides. I drilled the center section through and then spotted the centers to the sides with a small spotting pin.

I put in a 1/8” steel pin and glued it together and then glued it into the milled opening after fitting it so the pivot was exactly on the center of the split:


then I laid out the center of the brass bushings and the 1 1/4 candle hole and spotted them to the top section. I drilled all the holes:

With the pins in place to hold the alignment, I finished the next three cuts to make the obelisk:

Here it is put together and opened:

Only one thing to say:

Obelisk Navidad

-- Backer boards, stop blocks, build oversized, and never buy a hand plane--

Really a nice tour.
You sure are a man of precission, I like the idea of the spotting pin, I use these for dowels.
Nice detail whith the metal plate in the lid it must reflect the candle light really fine.
Best thoughts,
Mads

Thanks for the nice comments. Glad you all enjoyed it.
Mads, you gave me an idea when you mentioned the reflector. The next one will have a round mirror in it!
Thanks,Jim
