I potentially have the need to modify a set of big end shells to reduce their width to suit my application. They are being used on a NRE Weslake crank and I need to reduce their width by about .060in. They will be fitted to a Carillo con rod but are otherwise similar to what’s in a Commando. I’m wondering if any of the resident custom engine builders on the forum here have had to do this in the past and what techniques they've used. I have a small mill and a lathe and could conceivably make a jig for machining them. I am concerned however about any burring that might be raised on the machined edge and if something as simple as hand scraping the edge would be OK. I’d also be interested in how the manufacturers make the shells and what process they use for taking them to the finished width ( perhaps a question for Kommando?)
