I am going to hone the cylinders for a re-ring on standard pistons. I understand that when it is honed, it will be a little more loose. So, do I need to use a more aggressive honing pattern (a little more course) to help to fit the rings to the cylinder walls? It just seems like if the hone is more aggressive, it would help the rings wear in better.

Here is the most extensive thread on the subject that I have seen to date.

A brush hone is so easy, compared to a re-do if it fails to seat. So, why not bottle brush it? Moly rings can be problematic to seat. Get rings made from a turbo specific alloy.

I have had bad luck with finger hones, use the ball type.

This is what I use-

Works great. Put it on a slow drill, oil it up, and run it down through 6-12 times, then spray the cylinder out with brake-clean and rub it down with a red mechanics rag. This style hone only ''deglazes'' the cylinder, it takes a microscopic amount of metal out so you don't really have any issues with the bore getting bigger everytime. I broke 2 pistons in the number 4 cylinder, and everytime I re-honed it with this flex hone. Plus I honed it the first time on the original rebuild, so it was honed 3 times. Perfect compression everytime. I did find out what was breaking my piston and eventually got it to stop!
Oh and whatever you you do, DON'T use the 3 stone hone. That one sucks, it's hard to get a good hone, and they only last a couple hones. A flex-hone lasts like forever and is almost idiot-proof. The only bad thing you can do with is run it in the drill too fast. Oh yeah and never stop in one place, if it's turning make sure you are going up or down with it.
Well, I definately need something idiot proof! I'll get that on the way. And I will read that thread before I start. Thanks!

Bottle hone, berry stick, ball hone, flex hone...same thing. They don't really remove material unless you get crazy with it.
Use a light oil liberally on the bores and honing balls. Use a slow speed and fast up and down action to give a decent cross hatch pattern.
Can't really explain the speed and feed to use, but rpm about 4-5 times a second (240-300) and stroke up and down about 2-3 times a second. (that's up/down up/down up/down fast a second)
Stroke all depends on what rpm you do it at.

A strong drill motorhelps a lot in controlling the speed of a bead hone. A typical drill has too little power to overcome the substantial friction of the brush hone's beads so the only way it can drive the hone is at a high speed and that makes it difficult to control the angle of the cross hatching. So, if you can beg or borrow a strong 1/2 construction drill do it. Also, the big drills are typcially reduction geared and that makes them easier to control too.

Which brings up Black and Decker service centers.. Real pro drills for about half price. I always check there before buying tools.
Make sure the crank throw is at the bottom of its stroke and cover the crank throws with a rag when you do it and make sure to brake clean off the crank and surrounding area after your done. You don't want to leave any grit in there.

+1
+2 I was assuming the engine was apart and out of the car. The abrasive grit from any honing proccess is horrible. wash with plenty of brake cleaner and then soap and water and a bristle brush.+1

Oh yeah, now I'm not sure. I've done it both ways come to think of it LOL but lately it's been in car piston replacements
I never assume that when it comes to TM's,

LOL, so what are you saying?
+1, finger hones suck.
I've done a couple in car re-ring jobs, the one that used the 3 finger stone to do the honing didn't come out well. The ball hone worked great. I badly melted #4 piston, and melted a little bit of #2. (pushed too far on alky injection on a log intake.

Man, i bought the finger ones. :[
The good thing is i bought it with my autozone reward card haha, so it was basicly free.
I bought one of the finger ones, and it worked pretty well. I will say that the 4th cylinder that I did looks pretty darn good. The 1st... Well, not so much.
The finger ones do work, but it seems you have to have some skill to get it right on all 4 cylinders.
