Title: Honing ball Hone etc
Post by: Cut4fun . on February 15, 2017, 08:37:59 pm
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.

Should be here soon. Going to do both 54mm cylinders with it.

I've got a lot of em didn't know what I was doing when I bought them.  Wasted money on 180 grit hones.  Settled on 240 grit and 320 grit. 
Shep

I went with 240 Grit Aluminum Oxide. Copy paste info = This type is recommended for cylinder coatings such as chrome and Nikasil.
Used to lightly surface the bore of your cylinder, creating a cross hatch of scratches that helps your rings seat tightly to increase compression. They also smooth over imperfections around intake and exhaust ports.


Over this 320 Grit Silicon Carbide. " " " ".   This type of hone  works on all surfaces including cast iron cylinders.

Arrived today. Now to get some time to try it out. Havent used one of these since 09 or so and only once back then.

Will try and remember to take a before and after.  The one cylinder I deglazed by hand and cross hatched already like I used to do. But I am thinking this will be so much better.

I like to reuse oem cylinders when I can. I have always just deglazed the cylinders by hand.
Well I decided I wanted to go the extra mile and try and put in the oem cross hatching when new. Also think it will help with new ring seating.
First 2 pics show one I did by hand on LEFT and one on right waiting for me to do as pulled.
This is all before I use the drill and 240 ball hone to compare pics in next post.

Seems like folks on the CR G like the idea of these.    Many asking how to go about buying singles and set.

I never could figure out why the resistance against them.   Like anything else you can go over board on a plated cylinder but they do work well if done right.

Where are you getting them from. Sounds like they work well. Have a few cylinders I could try it out on.

Got mine from pmd or something like that on amazon. baileys sell them too and even as a set. But I refuse to buy anything from them.

 ;) I fired Baileys also for various reasons.Ball hones aren't that hard to find though .However keep in mind they won't round out or remove taper .Only a precision hone will do that .Then again most saw cylinders are plated and it's really a moot point .

Just want to show what a difference finishing touch of cross hatching does. ;)

First 2 pics.
Here is cleaned up by hand with emery cloth and flapper wheel.  See how you can still see the scuff area. But it is smooth as can be to go across it with fingernail or finger or whatever you want to use.

Then the next 2 pics are after the final step with ball hone  used for crosshatch.    :P

Any you guys using the SC ones?  They sent me a 240SC instead of the 240AO 57mm one.
