Fixed gantry Router made of steel

I did a video on how I built my fixed gantry router mostly made of steel:

Well done! Excellent build and thanks for the info. The more videos the better... For steel cutting with that spindle are you using "normal" chipload for steel and cutting faster or trial and error? Seems no vibration issues, the thick sections do the trick... If you are interested and capable if you could test the XYZ static stiffness of your machine that would be excellent information for us designers out here....Peter
