I BUILT A CNC MILL OUT OF STEEL FROM SCRATCH (Patreon)

Hi everyone!! 

Somehow I got carried away by the comments in the last video and decided to sharpen my welding skills trying to rebuild the mill out of steel. 

I remade the entire frame out of 40x40x2 steel box and TIG welded it using a technique called winging it. As a known side effect of this technique the frame is not square, straight, coplanar, or any of the required properties for the frame of a machine like this. I solved it by shimming almost everything on it with washers of different thicknesses and a lot of brute force. The machine is obviously more rigid than the aluminium one and after a lot of fiddling with it, it is surprisingly straight where it counts and seems to even be properly trammed. 

As a bonus at the end of the video I decided to obliterate some aluminium and steel with the wrong dull bit and completely wrong feeds and speeds.

As always let me know what you think in the comments.

Thanks!!!!
