Honing ball Hone etc

Honing  Ball hone etc.

Who is using these flex ball hone etc? 

Only time I used one was for my race 166 after it had hung a ring. 

Been reading up on them and may try one.  Then buy them all if I like.

Nobody doing this?    I'm just thinking of taking it that extra mile of de-glazing and redoing the cross hatch for rebuilds.

Checking to see if I had to use their flex hone oil.

The Flex-Hone REQUIRES the use of a lubricant. Always generously lubricate prior to use with 10-30 weight motor oil or BRM's custom Flex-Hone Oil. Hydraulic brake fluid may be used when honing hydraulic brake cylinders.

Using a drill, lathe, milling machine or CNC equipment, rotate the tool prior to entry. The tool will be oversized for the cylinder bore you are working with. Recommended RPM range 500 to 1200 RPM

The Flex-Hone is a low RPM tool. Do not use air tools or high speed motors.

Stroke 60-120 strokes per minute. Accelerate final stroking to develop a 45 cross-hatch angle.

Only use the Flex-Hone for approximately 20-45 seconds per cylinder. Do not over hone. Too much honing can result in the removal of material.

Do not use solvents when operating the Flex-Hone.

Thoroughly clean the cylinders after honing with a soft nylon brush using warm water and detergent. Oil the cylinder after cleaning to prevent corrosion

I have honed a bunch of my saws that I have rebuilt with ball hones.   I will run the hone in one direction and then reverse the drill and run it in the other direction.   I like the fact that it will soften the edge of the ports and it does remove any glaze on the cylinder.   It will also remove aluminum transfer much quicker than it does the any plating.   My saws run good and I have never hung a ring.   I also have never chipped the edge of a port either or gone through the plating of a cylinder.   Like most things there is a technique.   I use 320 grit ball hones and I have about 4 different sizes so far.   

I know there are pros and cons on this subject and these are my pros.

I have never used a ball hone in a 2 stroke cylinder, catching a ball in a port would ruin it. It does work well in four stroke blocks but use lots of lubricant to wash away debris.

Do you mean catching the edge of a port and causing it to chip the plating.   Other wise I do not know how you would catch a ball in a port.

Trying to reword my 166 wording in OP.

I had hung a ring on the 166. During clean up I used a flex ball hone to finish it off. I also done as Roger to knock off the glaze and went both way to add the cross hatching. 
I was impressed with it after using it and the 166 seemed to run better then it ever did even with new rings.

First time sounded as if I hung the ring after using. This was not the case. So hope I reworded so could understand.

I have ground on a few cylinders with a flex shaft and a burr and it would seem to me that you run a higher risk of chipping the plating on the edge of a port with a burr than you would with a ball hone.
