Charlie is our machinist. He is a retired machinist from GM, and has 40 years of professional welding behind him. He actually teaches TIG welding at a local community college. He is THE BEST welder I have ever known – period. And so after the numder of hours I had put into these pieces already, I wasn’t taking any chances. I can TIG aluminum – OK – somethimes great. But sometimes, the puddle gets away from me and it makes a mess. NOT an option after the amount of hours here…
