Surfacing cylinders after being bored?
I recently sent out my cases to be bored out 3mm and after getting the cases back, they seem to have some machining marks on the deck, and the deck was also lightly sand blasted to remove the plating after boring so it doesn't have the machined look anymore.
I didn't ask them the surface the block because it measured flat and was free of defects.
Are you able to lightly surface the deck after they have been plated with out damaging of chipping the plating? What kind of surfacing machine should I ask to be used?
