Few years ago I decided to build a cnc milling machine and today it's almost done. It took a long time to decide what to build. here is the result:
I had no access to milling machine so the only way for me was to use epoxy granite structure, because the mold can be done using wood from local supplier. unfortunately I loos the picture from the mold. I only have a picture of a test mold that I did before the real one:

Next pic is the assembling of the horizontal base and the column:
