This box was inspired by one I saw a long time ago while searching the net and thought it would be increadibly difficult to make to the necessry accuracy – filed it away at the time as a ‘maybe one day’ activity. Regretably I can no longer find that inspiration online to give attribution – perhaps it was someone here?

Finally decided to have a go as I have a couple of watches that needed an appropriate place to live.

The box is 15cm in diameter. The edges are American walnut and the inset panels are bird-eye maple veneer on mdf ground. Finished with sanding sealer and wax.

I had a couple of false starts deciding how to make the 12 sides. I started off trying to cut pentagons the full size of a side with the idea of veneering that with both the maple and using walnut veneer to form the edges. In the end it proved easier to actually make each side of each pentagon in sold walnut and then glue the 5 pieces of walnut for a given pentagon together around a dummy centre which was popped out once the glue had dried. That gave 12 penrtagon frames which was useful as I could then wrap tape around the edges to hold the overall dodecahedron together while glueing up the complet shape (obviously without glue around the edges where the box opens). The picture of the sketcup model may show what I mean more clearly. Once dry the walnut panels were glued in. Small embedded magnets hold the lid shut.

Awesome – Very Well Done. That is a quite complicated box, and yours turned out very well..

Thanks for sharing

Maybe from the cover of this book? I made a hollow copper dodecahedron based on that figure. It’s just the edges.

Do not know where you got your inspiration/challenge, but you made a great project. I am just starting
segmented turning and regular angles are bad enough, you and Sam Shakouri make those compound angles
look so simple and wonderful, maybe one of these days,LOL. Thank you for sharing and challenging.

Wow, That looks familiar.
Good job and welcome to the dodecahedron club.
The link provided above is to my construction blog .
The project is here: http://lumberjocks.com/projects/43503

I’m not at all sure that was easier than veneering both sides and just gluing up the pieces like I did but it certainly came out nicely.
More than one way to skin a cat. Congrats. It looks great.

This is geometry realized in a box. Excellent planning.

At Paul, There are now new breed of LJ who are inspired from your work. A day ago was Zebrabox from Martyn. And probably I will copy your hinge this weekend for one special box. Thanks for the experts who really are the mentors…

You and Shipwright must have attended geometry college together. What an unbelievable project. I salute you both! I get a headache just contemplating this build.

Hey I was just wondering what angle you bevelled the inside edges so that everything would fit together? I am about to build a dodecahedron for school. Thanks!

Theindigoyeti – I’ve added an image showing the ‘normal’ angle on a face – that was the key angle I calculated to build the box. Have fun!

Have your say...
