Stave130 Assembly Jig

(Tim)

Current Tooling• Components

– CF jig + ‘C’-channel jig & various face-sheet positioning aids

• It works!– Seems to produce nice flat staves

• What needs to change?– Geometry: 13 modules, width, thickness

• Are there any cosmetic/functional improvements?– One of the steel feet fell off!– Segment the vacuum channels?– Large number of internal ‘inserts’ of several different types – Think about materials for long-term use

New Jig(s)• Expect to be manufacturing 130nm stave cores by the end of

2013.– Procedures probably same as previously so ‘new’ jig should be

capable of manufacturing staves more-or-less immediately

• Proposed programme– Review design of CF jig and ‘C’-channel jig

• Identify components (eg inserts, edge close-outs, facesheets?) which could remain the same (i.e. drawings exist) and manufacture could start now.

• Identify components needing design revision & what input is needed to do so;– Eg ‘C’-channel jig needs stave width, ‘C’-channel jig fixes hole positions in CF jig.

– Suggest ‘mini-review’ at Oxford sometime late June/early July to discuss Jig requirements.• TJJ, JLC, GV, SY + (IW…. ?)

– Jig Schedule• Parts manufacture from now to end August• Stave Jig assembly from September (last one took 3 months – expect

this one to be quicker!)• Assembly trials from mid-October
