Using an air flange tool

[scherp69]

If I use an air flange tool for putting in quarter patch panels, will the flange tool cause the existing quarters to warp at all? Or should I go about 6", then stop, then go again etc? Any advice would be great.

Flanging the quarter has the ability to de-arc the quarter panel. Basically when you flange it, it will try to force the quarter panel flat.

Imagine taking a piece of sheet metal that has a curvature to it. Then imagine what the metal would do if you put a 90º bend in the panel perpendicular to the curve. Essentially that is what you're doing when you flange a quarter panel.

The effect will be pretty minimal... you are only flanging about 1/2" each time.
