Hi Ruairidh
Many with lathes will be interested in your activities. It is a while since you published a photo of the jig used. It could be easily reproduced by any keen amateur. Perhaps time to run the photo again ?
A bit rattled by the extent of cracks found. Yet failed con rods not a major issue on cars reasonably driven. Is there a pattern to the conrod cracks? I presume you mean in the steel and not the whitemetal. If mostly short straight extensions of the slit would seem of little consequence if the bore not distorted. Or are cracks random transverse? Garages and reconditioners used to indent with their straightening jigs. I have detected on other makes by testing at forging flaws.
