Normally for automated production processes, in this case the welding, it will take at least a few weeks to get things dialed in.

So unless you start seeing pre-production tooling trial run pieces within the next 2 weeks, the January 26 ship out date looks shaky at this point in time.

Not forgetting that you will lose at least 2 weeks over the X'mas / New Year period. So they will have about 6 weeks to sort everything out from this point forward though.
