Where I got my wood
I got my wood at many random places. Basically I am using 3 types of wood. First one is plywood sheet.

I got walnut from rockler.

I also got walnut from woodcraft.

I also got some oak from Dombo Building Supply.

I just want to try to see how different wood material feels when it is machined.
CNC files
All the wood is come with different size so I have to prepare the CNC file for different dimension of wood.






How wood feels?
Basically it is Walnut is better than plywood, plywood is better than oak. Walnut is just like chocolate or butter when machined. Oak is like vegetable with so many fibers.
