Re: babbit tolerance? .000?
Here's some pictures of fresh caps,the peining marks are visible on the rear cap, the front and center cap have the circular surfacing marks, and it was done after the cap was poured, the rear cap had the circular machining, then it was further smoothed in a linear direction
The finished cap shows very fine tool marks from the boring process, fine enough that they can hardly be felt with a fingernail
