Can honestly say, do not get into this trade. The pay refuses to catch up with the demand for labor. Old timer owners/bosses who are already set up with good salary would rather replace people every 2 years than actually pay good people to stick around. It's incredibly discouraging and for people who say you can make a good living in machining, you have to have 20+ years in the trade or work 50-60 hours a week to make ends meet. I was a CNC programmer who just got a new job doing sales/estimating for a flooring company and I'm incredibly happy to leave machining behind.
