ID this honing machine

[carl hinkson]

I am kind of partial to my Sunnen 616 Cylinder King, So far no sold on Diamond honing I do have Diamond stones for roughing only.

The stone packages I use for performance honing you can't get for the AN hone.

Manual machines are challenging to use and to get a consistent cross hatch from cylinder to cylinder is hard to do along with consistent honing pressure.

When plate honing blocks you need to leave about .005 to hone out and on OEM 400 blocks you need .008 and thats alot of work with a manual machine.

Sunnen stone hone heads are great for making a round cylinder because on stone is 10 degrees ahead of the other stone, With a hone head that has stones and shoes 90 degrees apart they really do nothing to make a cylinder round as when one stone hits a high spot in the cylinders it pushes the other stone in the other side of the cylinder.

Best way to combat that problem is to bore and hone with a torque plate the only issue is your using short bolts in te plate which i snot recommended.

Remember its impossible to measure a round cylinder with a 2 point gauge.

Hendrick Motorsports has probably done more research on honing and they still use Sunnen 616's to do the job with stones.

Again I am not sold on Diamond honing yet ..............
