03 Nov 2015. We found rust on center-part (E1T => #250315E1T) then we stop assembly all of step# and separate the good pieces to reuse (Pusher, ball and spring). In step#7 the 450 pieces standby to close the top side. We do not close the top and move all of 450 pieces go to machine of step#6 for remove the goupille out from Bouchon. But Tsering send the second email to tell Tiger can finish assembly step#5 to #8 (QC)..... We back to assembly. But, 236 from 450 pieces have mark that is the reason why have many bad pieces in step#7!
