Pro tip: my old lead tech said my roasts sounded 'sloppy' so I changed how I hold the torch
Back in 2019 I was doing a rear subframe on a rusty 2004 Tacoma and my lead tech walked by and said my torch angle was off by about 20 degrees, which was why my roasts looked like a beaver chewed them. He showed me to keep the tip perpendicular and let the metal heat up instead of chasing it, and I fought him on it for a week because I thought I knew better. After I finally tried it, my uglier roasts cut my grinding time down from 15 minutes to maybe 4 on that same job. My cut off wheels also stopped wearing out so fast since I wasn't pushing sideways into the steel. Curious if anyone else had an old timer point out a small thing like torch angle and it turned out to be a game changer?

The "beaver chewed" part got me because I had the same deal with my stick welding in shop class years back. Instructor kept telling me my travel speed was too fast and I was basically dragging the rod instead of letting the puddle do its thing, and I shrugged it off till I watched him run a bead that looked like a stack of dimes next to my bird poop welds. Turned out slowing down and watching the puddle edges instead of the arc fixed like 90 percent of my problems. Funny how the small stuff the old guys harp on is usually the stuff that actually matters.
