Finally Austin and me finished making the wooden handle for I/O brush. It's an interesting experience in MIT Hobby Shop. That's a professional wood workshop. In How to Make class and Media Lab fabrication shop, there are more compuatinal fabrication tools and machines. But in Hobby Shop, Kenneth, the lab master, has a different approach. We basically hand made the entire stuff with low tech machines.It's a unique experience for me to know how to work with wood from sratch. Austin and me are very happy with the outcome, the color, the weight and the texture are very hard to achieve with other materials on CNC or 3D printing machine.
1)Jointer to flatten face of mable wood block
2)thickness planer to make parallel faces
3)adjust the angle of knife on table saw, and cut wood to form a 60 degree angle
4)glue 6 piece together
5)lots of work on wood lathe. outer knife to create cylinder shape, inner knife to make cylinder holes; there are lots of things to learn about how to operate lathe, such as how to fasten the wood piece, which knife to choose, how to set the step distance and speed, etc...
Most important thing is: take you time, be patient, the quality of object is normally proportional to the amount of time spent on it.
