Went from guessing tube lengths with a chalk line to a $4 stop collar and it saved me a whole shift
Spent my first two years on the tools measuring every water wall panel by hand, marking it with a chalk line, then hoping the cut was close enough. Last Tuesday I was on a small package boiler in Council Bluffs and finally tried a simple stop collar on the tape, the kind that clips on and locks at whatever number you set. Same panel layout took me 40 minutes instead of most of a shift, and the cuts landed dead on the first try. No fancy laser gear, just a $4 piece of plastic, and it beat my old method flat. Curious what small cheap thing changed the game for you guys.
