My Lamp made from plywood. Sorry about the photos. It’s quite difficult getting a good picture, when photographing into the light.

I first glued to pieces of birch-plywood on top of each other to get 18mm. I then made a 5-sided cylinder.
I then created “slices” from it using the tablesaw. I could find a way to create perfectly flat slices. I used several jigs. But there was always a slight mis-alignment between the sides. I ended up just eyeballing it, which worked out okay. In my prototype, I had the grain of the top layer oriented the other way, which resulted in quite a lot of tear-out.
You could see the mis-aligments, but barely feel them. After some sanding they were gone.
I sloped the sides of the slices by putting it around a five-sided piece of MDF I screwed onto a table-sled. After sawing all 60 sides, I had to put it all together.
I first glued them up in groups of 3. The glued those in pairs, and finally put the two pieces together. Not perfect, but damn close. I had expected worse, since having 12 sides, a slightly wrong angle and you end up with some gaps.

The ceiling cover (what do you call that in english?) is also made with plywood. I made it five-sided, to keep the theme. I calculated the angles using the table provided on woodgears.ca.

Finished with furniture-oil, as it accentuates the layers in the plywood the most. I filled in the spaces using white plastic from those tabs used in folders. I still want to wrap the electrical wire in a braided sleeve.

I really like the end-result. It’s like a glowing orb floating above my coffee-table.

Very nicely executed.

The Plys make a great contrast accent.

Quite impressive. Thanks for sharing. – Grandpa Len.

That must have been quite the challenge figuring out all those angles.

@sskwoodcraft not really. The angles can be found on Wikipedia (116.56505°). Just divide by 2 and subtract from 90 to get the angle of the sawblade. Long live the internets.

Have your say...
