I probably already know the answer to this ...

Can you hone you own Wrist Pin Bushing? I had one that was a little loose so I put in 4 new brass ones from Stoddard.
Can you hone these or are you at risk of getting out of parallel to the Rod Journals? Or is this a machine shop only task?

Bill,

.0005 or 1/2 of a thousands of an inch . Are they using a device called a "bearing master" ?

Bill,

The .0008 spec is for A/B rods.
