Today I was able to complete the deburring I started 2 days ago, got KitLog working on another computer & deconstructed the factory assembled cabin heater splitter box. The heater box had been incorrectly assembled with the hinge installed upside down and the cable mounting angle was incorrectly sandwiched between the body/hinge & bottom plate. I will need to replace the hinge with new & manufacture a new bottom plate as the holes that had been countersunk are way oversize for a 3.2mm rivet. On call again for work tomorrow so might be able to get some of this done then.
