How can I make a real metal laser cutter at home & what are the instruments needed for it ?

It would be much easier and cheaper to make CNC plasma cutter, which basicly does the same thing, but will not cut non metal. you could probably make one for under $2000 google CNC plasma cutter

Some mechanical, electrical, electronic and software skills.
