ID this honing machine

Thanks for all the info guys, I know the difference between the CK and an air assist but figured if the guy was willing to take a low offer I might grab it, he's been trying to sell it for about three months now and the fact that it's filthy isn't in his favor, Paul.

X2 on Adger's reply.
It takes practice and skill to use hones with AN sunnen hone head,but can do good work with them,I have used CV-616 it is more operator friendly,but I was experienced with AN head hone first.
I have peterson hone that has air powered stroke,when needed let off pedal and manually operate at times,I had one that had air assist you pulled down and air cylinder helped push back up.

hey paul you could bore/hone lots of blocks and have some income. $325 around here for that. farm out the degrease/decking and your ready for assembly......I believe the 777 bar and the hone cleaned up (new sunnen head, that's good) is a great combo...

No problem with decking, I'm picking up a Storm Vulcan 85B next month as soon as the guy has his new machine in place. I had an 85B in my old shop in NH but parted out of it with a friend back in 2004 as I had no place for it at the new home in PA. My retirement home as I call it has 1.5 acres and enough shop space to make it happen. I plan on setting up a small 30 gal alkaline degreaser with a barrel heater just for heads and small parts, we had a 300 gal tank in NH but it took 24 hours to heat up so we ran it once or twice a month.

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 ..............

It's always very interesting to read your posts about block prep and honing.
