How do I avoid the loose bull-nose pivot drift

Plain-English answer

You are using heavy bull-nose snips (bulldog shears) to chop through a thick 16-gauge TDC flange seam reinforcement lip. The blades slide sideways and slip right over the edge without cutting, merely bending the thick steel profile out of square.

Heavy gauges will force loose snip blades to drift apart. Tighten the central pivot nut on your bulldog shears using a wrench until the blades require a firm, manual pull to cross, or use an angle grinder zip-wheel instead. Keep the metal deep in the. The likely recovery is to check the tool setup, correct the prep or technique if it is within your assignment, and bring the journeyman or foreman clean information before the work creates rework overhead.
