Cylinder honing help?

[todapark]

I'd like to know how to get a crosshatch pattern on my cylinder walls. I bought a flexible 220grit 3 bladed honing tool and used it with kroil oil. The cylinder walls are now smooth and when mic'd are in spec for my motor, roughly a 3.376 average diameter. I've read about the importance of a crosshatch pattern but the more I hone the more I get a smooth surface with no crosshatch. I am moving the honing tool in and out as it rotates but still no cross hatch. Ok experts and old timers what is the technique for getting a cross hatch pattern?<br />What about the rotation speed of the honer and the in and out motion speed? Any advice at all is appreciated, Thanks?? todapark

Does that honing tool have a tensioner to adjust the pressure outward on the cyl. walls?? If there is not enoughpressure, you may be burnishing the walls,, just a hunch, though.

Yes the honing tool has the tension adjuster, I was afraid to use too much tension so I only turned the adjuster about 1/4 of the way in.<br />The surface of the walls do now have a burnished look to them, do I need to tighten the tensioner? Also I have been honing in only one direction, counterclockwise as you look down from the head portion of the block. More questions, should I reverse the direction, once again what about speed, also how much kroil oil should I use, should I be able to feel the honing stones "bite" or should it be a smooth rotation. Yup I'm a newby at trying this but then I have learned from all my mistakes in the past and this will probably be no different. All advice is still welcomed?? Also what duration of time should I be running the honing tool, ie 5 minutes at time , 1 hour??? Help

Does your motor have the chrome plated bore as some mercs did? If so you don't (can't) hone them.

No the cylinder walls are base metal and were not chromed.

You may have loaded your stones. Try a solvent, or as I have used in the past by suggestion, brake fluid.

Found the answer. I was rotating the honing tool way way way way too fast. Once I slowed it down to where I could actually see the stones rotating with no vision blur, I got a good cross hatch.

Right on. Use of a variable speed drill is mandatory. Just visualize the angle of the crosshatches as the hone is going up and down and keep your speed commensurate with that.<br /><br />Remember you're just trying to deglaze the cyl and put a bit of hatching on it, you don't want to do it excessively to any of the cyl's. Shouldn't take more than a minute per cyl to clean them up.<br /><br />Keep spraying plenty of oil as you hone, it's a bit awkward to have the oil spray bottle in one hand and drill motor in the other, but you get the hang of it after a while. Marvel Mystery oil does do a great job. I've also used 'WD' and it seems OK too.<br /><br />HTH and Happy Honing.........ed
