Tungsten Bucking Bar Set

Tungsten bucking bar works in-tandem with the clutch actuator bearing to transfer the signal from the clutch lever to the clutch itself.

Tungsten Bcking Bars

Tungsten bucking bars weigh almost twice as much as conventional steel which helps with reducing vibration as your rivets will require less blows to set them.

Back Riveting-Bucking Bar

Back riveting is a method of setting rivets, usually in a skin component, by striking the buck tails with a special gun set while the flush head is securely supported in its dimple or counter sink by a steel plate or bucking bar.

Control surfaces are usually back riveted using a horizontal steel plate mounted on a table.  The skin rivets are held vertically in their holes with thin Scotch Magic tape or fine Mylar tapes over the heads.  The internal rib or stiffener is placed over the rivets and the special gun set is used to sequentially set these fasteners.  

Bucking bar orientation

1. Rest bucking bar on inserted rivet and try to locate its point of balance.
2. With gun set in place, use bucking bar to push rivet (and gun assembly) outward.  Bucking bar will then register at right angles to the rivet as it comes to rest on the aluminum.
3. Push rivet back into place with gun set and reposition bucking bar, if necessary, to maintain its point of balance on the rivet. Often the index finger can be placed on the back of the bucking bar directly opposite the rivet tail. It then becomes the 'sensor' for correct bar position.
4. Pressure is held on gun while riveting.  Bucking bar is held with only moderate force (otherwise rivet may be set with head proud of surface). A rubber grommet may be used over the rivet tail to assist in squeezing parts together during riveting.  It acts as a 'pressure plate'
5. Duration of riveting is determined by experimentation with a test piece or previous experience.
