separating the caps on the auxiliary unit con rods

the aux con rods still have the internal detail for the roller bearings to be completed. this was left till last because obviously wen the caps are split the hole would become oval by the amount of material lost when splitting the caps, this is being done with a wire eroder and we loose about 10 thou, the original had a flat surface and the alignment was achieved purely by the fir of the bolts ( which was good) however I realised with this technology, not available to Abner, we could cut a location "Vee" into both sides and do better
