I am trying to learn how to hone using the 3 stone hone rented from auto zone. I am using a block that is bad to learn on before I do it on my good block. Does this look ok?

OK, This is far from OK.

The 3 block drill hone is garbage.

You will need a Flex-hone at 240 grit (280 would be best but not avail)
you need to have the cut at a 60 degree angle

Heres my hone I did myself with a Flex hone.

Will a flex hone remove surface rust? I have some rust in my hope to be good block. It does not seem like theres any pitting.

Did you use any WD-40 or cutting oil when you tried to hone it?
Did you tape the old gasket to the block while using that hone?
Did you pull out the hone quickly after honing.

I cant tell from the pic, but it looks like the edge of the cylinder is worn.
Those cuts look pretty deep.

The flex hone isnt a miracle worker.

Post up some better pics

I used ATF in that hone, the block im using is trash its just for practice really. 3in 240 grit flex hone would be what I would use? I think the cuts are deep cause the 3 stone hone from autozone is just too course.

This is the rust on the other block i have, I cleaned it up and it looks much better now but rust is still there, surface rust for the most part. I got the block for free so its worth a try, If the flex hone wont remove the rust I will have to risk with the 3 stone. Worst that can happen is I cant fix a block i got for free.

did you move it up and down? From the pics, it looks like you just left it in one spot. I would suggest you move the hone up and down at a constant speed so you get that nice 45 degree cross-hatch pattern. Lots of lube and steady hands will take you far with honing (thats what she said) good luck

i would agree that your first hone doesn't look too good. No matter what rings you would use, they all call for a 45-60 angle for the cross-hatches. Those in my opinion look like less than 25 degree lines (being generous) I can post pics of my block when i pick it up from the machine shop hopefully tomorrow if you would like.

From videos ive seen of people doing diy hones, you have to be very agressive in how quick you choose to move up and down within the cylinder, with a consistent speed across all 4. Also make sure you are quick to pull it out of the cylinder and that you keep the drill working until it is clearly out of the cylinder.

Hastings rings call for 220-280 grit final hone, and i found a 3 grit honing tool on amazon a while back that seemed pretty reasonable to me. honda rings call for a 400 grit final hone as per any service manual.

Did you check on your block first of all that the bore taper isn't significant? it was because of this reason that i choose to go with bigger pistons and a fresh bore and hone.

I also dont like how the cuts look, it may be because of using atf but probably it is not the case. either way, i would use some sort of more standard motor oil, and it may possibly produce better results

That does not look good at all.... stick with it and try different stones and methods.....


I suggest not using engine oil, cutting oil or WD-40 to lubricate while honing. Use a lot of kerosene. Maybe mixed with a little bit of ATF. You should be using a 3 stone hone using the specified grit stones that are required for the rings that you are using.

Maintain a 60° cross hatch pattern. This is achieved by keeping your drill RPM lower and your up down motion quick and steady. Try to limit the complete revolutions to 20-30 complete turns. If you cannot remove the rust or get a good even cross hatch pattern within this duration your cylinders will require an over bore and hone job.

here is my take at honing at home (in the yard actually). 400 grit flex hone i hate using the 3 stone hones. ive found that making 1 pass up and down in the cylinder about every 1 second gets a decent angle and pattern. keep the hone and cyl well lubed. ive been using atf but there are other options as ghost accord said.

clean quickly afterward with warm soapy water, dry out with some air then throw a light coat of wd 40 on the cylinder walls.

400 grit flex hone using tap magic as a honing lubricant, cleaned afterwards with a hone brush and dish soap and water. You have to keep the hone moving at a good pace and dont use anything over 1300rpm or under 800rpm. You want a 45 degree crosshatch for the best finish, but 60 degree will work too.
