1. Bolt insertion methods

   • Percussion
     • Toffee hammer (current method)
       • Low force output
       • Can it be improved?
     • Standard hammer
       • Bad for parallel structure
       • Low force output
     • Slide hammer (Alan Thompson, MA)
       • High force
       • Inline
         • Good for missing parallel structure
       • High accuracy
   • Compression
     • Scissor clamp
       • Ball joint splitter
         • Bad for parallel structure
         • Potential of slip
         • Awkward to use
     • G clamp
       • Standard
         • Could slip
         • Low force
         • Clumsy
       • Custom
         • Fits 7/16 head
         • Low force
     • Hydraulic piston and pump
       • Small
       • Powerful
       • Expensive
       • Loss of control
       • Piping
   • Thermo expansion and contraction
     • Expansion of torque collar
       • Lack of space
       • Dangerous
       • Unlikely to get approval
     • Contraction of bolts
       • Liquid nitrogen
         • Used for insertion of bearings
         • Trained personel
         • Non renewable
         • Fast
         • Might need a second method aswel
         • Expensive
