Install tooling & training
- Tool
- Rivet gun + bucking bar (both sides)
- Special / proprietary
- Standard tooling
- Training
- Standard sheet-metal skill.
- Inspection
- Shop-head diameter/height gauge.
Driven with a gun on the head side and a bucking bar on the far side — the upset requires back-side access and impact, which crushes/delaminates composite.
