Cornice brake
Heavy metal forms, available in various shapes, such as curves and angles.
Stakes and stake plates
Fingers allow for just to width
Box and pan brake
Bends, Folds metal up to 1 inch
Bar folder
2 front 1 rear
For formatting sheet metal into curves and cylinders of various diameters
Slip roller
A bench mounted machine with two removable rollers that enable the main mechanic to burr, turn, wire, bead, and crimp sheet metal
Rotary machine
Types of rolls
Beading, turning, Wiring, crimping, and burring rolls
Countersinking methods
Machine, Dimple, and combination method
Used when one metal sheet is too thick to be doing board and the second sheet is too thin to machine countersink
Combination method
Three types of dimple countersinking
Press, coin, and hand
For dimpling soft alloys and metal of .063 of an inch thickness or sooner
Press dimpling
Reduces circumferential cracks
Similar to press dimpling except that the female part of the dimpler is equipped with a spring-loaded ram
Coin dimpling
Normally made of a solid piece of aloe it still, that has one or more highly polished sides
To shape the Buchtel of a solid shrink rivet
Bucking bar
Hollow Shank rivet that has an internal feature to form its bucktail
Used on components in place of solid shank rivets, when a bucking bar cannot be positioned properly
Blind rivets
Shank, Stem, locks
Mechanical lock
Works the same as a mechanical lock rivet, except the stem is held in place by friction
Friction lock
Has interchangeable heads for different rivet diameters and rivet head styles.
Drives friction lock and mechanical lock blind rivets
Hand operated gun
Has interchangeable heads for different rivet diameters and rivet head styles.
Drives friction lock and manual lock blind rivets. The pulling pressure can be regulated for a specific rivet size
Pneumatic gun
Used only for hi-shear strength applications
2 parts stud and collar
Hi-shear rivets
Bolt nut and sleeve
High strength blind Structural fasteners, consisting of three parts
Jo-bolts
Light metal that is often circular or oval shaped
Vertical rings
Stronger and heavier than vertical rings, giving shape
Formers
Vertical members that are used to close one area from another
Bulkhead
Principal longitudinal members that are heavier and construction than a stranger and run the entire length of the fuselage
Longerons
Principal chord wise member that provides shape and rigidity to the wing
Ribs
A main span was member that is designed to take bending loads
Spar
Longitudinal member that runs span wise in the wing
AIDS in maintaining the contour of the structure
Assists the spars in taking the primary bending loads
Stringers
Two types of wings
Cantilever and rotary
System of line is designed to measure point of location on or in aircraft the lines present an end view of a plane cutting the aircraft at a particular location
Aircraft stations
Indicate vertical planes parallel to plane of symmetry
Buttock lines
Indicate the longitudinal position of vertical plane is perpendicular to the plane of symmetry
Fuselage stations
Indicate horizontal plane is parallel to the ground

Dance or removed or repaired in accordance with limits established in the what
Structural repair manual
External past it was flat on the skin, covering the damaged area
Lap patch
Consist of filler, which has the same sickness and out-of-the-way as the skin and the doubler the doubler has the same our way as the skin, but is normally one gauge thicker
