Now you will notice that after cutting the second cap up in the first photo, it now only has a small area that didn't clean up. I didn't want to keep grinding his cap away, so I left the patch there as it was still fairly deep. I just need a flat surface, perpendicular to the mating surface so I can cut it. The other caps cleaned up nicely without grinding much.

When cutting the mating surface, I need to know how much I'm cutting off, so I set the cap on a dial indicator so I can keep track of how much I cut off. That way I can cut all the caps the same and have housing bores close to each other when I start honing. The target amount to cut off will be .004". That should be enough to get a nice round hole, with all bores the same size. Any less, and it's usually not enough to get it all round again if you are installing studs. Especially when installing new dowel pins like I did in this.
