The loose bull-nose pivot drift
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.
Stop if
- The blades are crossing over because your central pivot nut is loose. Cinch that bolt down tight so the jaws can't drift apart, and keep the thick steel buried deep in the throat of the tool to get your leverage.
Watch out
- Do not force the tool through the problem or substitute the wrong tool just to keep moving.
Check
- Confirm which snips or shears match the cut direction and metal thickness.
- Keep the good side of the sheet flat and let the scrap curl away.
- Use short controlled strokes instead of fighting the tool.
- Stop if the blade drifts, binds, or starts tearing the sheet.
- Correct the tool setup before the edge turns into rework.
