The short-jaw fold slip (wavy flange edges)

3-inch tongs cannot hold a wide sheet steady over a long span without drifting. For long straight folds on the ground, use a 24-inch or 36-inch hand folding bar (bar folder). Slide the raw metal edge into the precise 1/2-inch depth slot, grab both handles,.

Stop if

• Don't try to step-tongs a 36-inch wide layout-it looks like a roller coaster. Slide the metal into the bar folder slot and roll the whole edge up at once so the fold stays completely straight.

Watch out

• Do not force the tool through the problem or substitute the wrong tool just to keep moving.

Check

• Check the raw edge, pocket, or overlap before locking the joint.
• Seat the tool fully and square before applying force.
• Use a full controlled stroke when the tool needs a mechanical lock.
• Test the fit before sending the piece overhead.
• Remake or re-edge the part if the lock will not hold.
