Torque plate
IMO shops that bore within .002" then hone are taking shortcuts. You have to leave enough material to use a series of stones, in order to leave the subsurface with the proper depth of cross hatch to hold the oil. AKA Rvk value.
I see alot of blocks come in that have been shallow honed and the cylinders are glazed and missing the crosshatch from not being able to hold the oil on the bores properly.
Like Moper said- its a bunch of work and adds another accuracy issue to bore and hone with a plate.
I personally leave .005"-.007" depending on the block and bore size, and just finish hone with a plate.
A good hone is designed to make round holes, and can take out material very fast with the right stone and operator. I've taken several blocks and honed them .010" to the next size starting with an 80 grit stone.
