Default installing new rings....need help

ok so i have done many swaps but never a ring job. i have already bought bead hone and honing oil. now i have read the instructions on the back of the bead hone, and it says to...

1. Have the felx hone rotating upon entry and removeable from cylinder
2. recommended rpm range is 500-1200 RPM. do not use air or high speed
3. use 60-120 strokes per minute depending on RPM. Final stroking may be accelertated to devlope 45 degree cosshatch
4. hone each cylinder for approximately 20-45 seconds
5 clean cylinders after honing using a cylinder wash brush, warm water and detergent.


ok so my questions are....

1. so i oil the cylinder walls first before i enter the cylinder to scuff up the cylinder.
2. set the drill at the recommended rpm range and while its in the cylinder do an In and Out motion to what i think 60-120 strokes per minute and slightly accelerate it for the final strokes to achive a 45 degree crosshatch(like a basketweave)
3. using a stiff brush, warm water and dish detergent scrub the cylinder walls to clear all debris from walls and then reoil cylinders to prevent rust.


does it sound right? or is there an advise to make sure the crosshatch is correct.

i really want to try to build this motor without going to a shop, since this is the only aspect i have never done and would like to try it aleast once.


all advice is appreciated.

Your instructions are fine. The only issue is how worn are your cylinders. They could be uneven top to bottom or ovaled. In either case, all you would be doing is cleaning up the surface of lopsided cylinders. If they are bad enough, you will end up with compression loss and uneven ring wear.
The only way to tell is measuring the cylinders with a bore gage or mic.
You can take your chances and just clean 'em up and put it back together, but you won't really know what you have just done - something good or bad.

I just did this to my buddys civic.
Use a rigid stone hone not a flex ball hone. I used wd40 to lube the cylinders while I honed them out.
500-800 rpms...Fast speeds can take off to much material and instead of a hone job, youll end up with a bore job.
20-45 seconds is too much imo. After all the research I did I decided to hone for 10-15 seconds for each cylinder,
Dont try and remove all the scratches in the cylinder. Just give the rings a good surface to bite into.
Def. wash with soap and water. Wash it several times extremely well.
After about 20 miles of break-in, the compression is so good, I can barely rotate the engine by hand with the plugs in. This was a stock 2000 civic btw..
Good luck and practice on an extra block before you do the real thing!

I prefer the flex hone myself. You don't need to stay in a cylined for 20-45 seconds to get a good cross hatch. Try 10-15 seconds. Clean the cylinders with soapy water, then brake parts cleaner or acetone and then re-oil. Like already said you are not going to fix an out of round cylinder with a hone. I've honed a couple of Hondas and a lot of bmw's with this method and it has worked well each time.
