Good luck, it's a tough thing to get into. You need more machining and a metal working back round IMO to smooth out the learning curve. TIG welding, brazing, soldering, tool making, and metallurgy basics are good to know when starting out.
There are 3 kinds of people in this world.
The wise, learn from the mistakes of others.
The smart, learn from their own mistakes.
The others, well......they just never learn.
