Materials

3.5 Inch Solid Wood Block Cube: from Amazon

1/2Inch Baltic Birch: from Rita, and she bought from Prince Lumber

Wood glue;  1000 and 1500 Grit Sand Paper;  Tung Oil Finish and Paste Finishing Wax : from home depot

Lighting components: from the lighting shop(crazy expensive)

PS: I bought a regular bulb at first, but it generated a lot of heat, which was not good. Because I used a lot of glue on the lamp shade. So finally I had to choose the LED bulb.

CAD File

PS:The maximum diameter for a cylindrical workpiece on 4 axis mill is 5 inches.

I made the model of my actual workpiece, and then put the lamp shade model into it, in order to make sure there won’t be cutting-through parts.

In order to fix on the 4 axis mill, the left bottom one without a hole in it will work as a sacrificial piece placed at the bottom of the workpiece.
