Asked about these angles a while back, finally got them right and got this lamp built. This is a Dodecahedron hanging lamp which is a framework of Pentagons. The electrical is a couple sockets with large Edison styled bulbs. The junction box is 2 pentagons screwed together with the centers cut out to make it a box for the light connections. The overall height is 42” with the frame work being 21”. Each strip of Walnut is 9” long. The frame is constructed out of 60 pieces of Walnut that are ripped at 31.7 degrees with 36 degree angles at each end.

All the Dodecahedron lights I have seen have one bulb and the top pentagon is covered by a full size piece of wood by which the lamp is hung and the light suspended. My version has the dual light junction box suspended by chains as is the whole fixture. These changes prevent my light from being a copy of someone else .

I built this lamp as a one board challenge from the Kyanna Woodcrafters Club. In June, the club issued 8’ Walnut boards to the members that signed up for the contest. The club meets on the first Thursday of each month and we will be judged by the members at the September meeting. No prizes involved, just bragging rights for a year. LOL

Questions or comments, good or bad are welcome. I am considering writing a blog on this build, but not sure yet. Thanks for looking. Dan

Awesome job, Dan. I really thing the suspended center adds that special touch. Are the light bulbs LEDs?

The math is making my head hurt, also…I wouldn’t ever hang that in my house, because it would give me a constant headache… (-:

...and to think I once did math puzzles for fun…

Great solution to a one board challenge…
