Swore I'd never use a torque multiplier on a boiler manway until the stud snapped at the Alvin plant

Last Tuesday we were buttoning up a 60 inch manway on a waste heat boiler down at the Alvin plant and I was dead set on doing it by hand with my old 4 foot cheater, because that's how I came up and a multiplier felt like cheating to me. Sure enough on the third stud from the top I lean into it and the nut grabs and the stud shears right off flush with the flange, and I just stood there holding my wrench feeling like a fool while the whole crew went quiet. My partner Reggie, who has been doing this 30 years, didn't even say anything, he just walked to the truck and came back with the multiplier and a fresh stud. He showed me that if I set it to the right ratio I hit 1200 ft lbs smooth with no jerking and no guessing, and we had the next five studs snug in half the time it took me to break the one. The part that convinced me was pulling the old gasket afterward and seeing the crush was dead even all the way around, something my by-hand pattern never got close to on that size flange. So the multiplier lives in my bucket now and I don't miss the cheater one bit. Anybody else get stubborn about old methods and have a moment like that, or am I the last guy at the plant to come around?
