Well, there's a new development...DH called an old friend of his from HS who has been a welder for about 40 years. This friend lives about 45 min away and we see them a few times a year. DH asked him his opinion about what DS27 should do about getting into welding. DFriend was very positive about it. In fact, he even offered to bring DS on-board as a welder's helper to give him a good taste of the work. He goes to the scrap metal yard several times a week and he needs some help with that, too. DFriend is an easy-going guy and a good teacher. He warned that welding is hot, dirty work; DS is of the mind that he's willing to be hot & dirty to make decent money.
I think DS will like welding. What's not to like? Big tools, lots of sparks. Almost like having super-powers.
