[QUOTE=Larry Hill;602288]Does the cap grinder cut the cap 90* to the bore? At .0006 taper per inch, it would taper .0072 per foot. That's a lot.

It might take truing the mandrel a few times to get rod to size using a slightly lower stone pressure.

If accepted size is 2.5000 to 2.5005 is any size on or between good or is there a taper tolerance " Tapper not to exceed .........."[/QUOT

The cap cutter would be dialed in @ 90 degrees, setup with the horse shoe.

How would the rods be put on (position) the mandrel at the start of the honing?

Chevrolet BBC rods from the factory sometimes the mating surface is not 90 degrees to the sides, which will cause taper when the mating surfaces are cut.
