New drawing F.Maletta Can bemounted in with the “original” or “inverted” approach M.Lenti
Prototype situation • Aluminiumraw material arrived last week (!!!) • Executive drawingsready • Mechanicalworshop in Florencereadyforworking • Hopetohave the piecesmachinedbynext week M.Lenti
Resonances • Estimatedby Vito • Glass: very low, just above 0 Hz • Supportstructure: 1° resonancearound 7.5 Hz M.Lenti
Conclusions • A lotoftimelostfor material procurement • Hopetohave some results late in july… M.Lenti
