Trying to cut steel on Homemade Milling Machine

[engineer steve]

I tried to cut some steel on my homemade milling machine, as you can see it doesn't like that very much. Some things I want to change are: better milling table with dovetails, more powerfull motor and bigger spindle(with standard taper and bigger bearings).

If you have more ideas that will improve this build, let me know, Thanks!
