Tool Topic: Cylinder Hone, Ball Hone, 3-Stone, or ???

What do you all use to hone/deglaze your (small) cast iron or sleeved cylinders?

I bought a cheap 1-1/4” thru 3” hone with three 2” stones off Amazon a couple years ago. I’ve used it a couple times on moped cylinders with varied success, and today I used it in a Kawasaki ke100 cylinder with a 49.5mm bore. I say varied success, because the stones would occasionally catch in an exhaust port or piston skirt, and bend the arm to shit. No biggie, just pull it out, straighten it up, and go again.

Well, on the 100cc cylinder, with a little bigger exhaust port, and skirts, the stones caught & popped a couple stones off their steel backing. I superglued em back on, straightened the arms, and went again. Just as I was finishing, the stones caught again, this time busting two of them. But at least I got it honed.

I know I can buy replacement stones, but I’m wondering if this $15 hone is worth it. I could buy a few different size ball hones, for different size bores, but that gets expensive and ball hones can chamfer ports wrong. What do you all use on small 2 stroke cylinders? I don’t want to spend a fortune on a tool I only use a couple times a year.

How you all honing yer holes?

I just borrow a 3 stone cylinder hone small enough to fit inside the bore from one of the auto parts stores , if I intend on taking a lot out , like for over sizing .

Other than that , I have a worn ball hone good for about a 2.5" bore and it fits nice and snug in my 41mm FA50 bore . It doesn't take a lot to produce a decent cross hatch pattern .

And , I've never had a problem with any chamfering . Maybe because I don't spend a lot of time in the cylinder .

I also have a brake cylinder hone , but , it's too small and catches ports .

None of the above^^

Always used the ball hones with as-expected results, use plenty of oil

I tried a brake hone for a couple passes once but it wasn’t proper, I think the pads weren’t long enough, it just wanted to catch on ports too easily

The ball hone chamfers port edges a bit as well

I dont know what the scotch brite thing is but that cylinder will have plenty of oil passing by the rings

Re: Tool Topic: Cylinder Hone, Ball Hone, 3-Stone, or ???

My vote is also ball hone

I brought a rijid 4 stone hone with adjustable cam action stone holders on ebay. 4 sets of different grit stones. I went to use it and it doesn't go down to the advertised min diameter. I had to send it back and I ordered the next size smaller but similar Atoz brand on Amazon. Takes almost a month to get in from India, I'm not happy about that, but the build quality is good and it should be fine for honing and even resizing 2 stroke cylinders. I made a custon workbench and found a heavy duty drill, got some ID telescopic gauges and a 1-2" micrometer from an old machinist.

^ This, or a 2-stone brake hone.

Aluminum oxide ball hone in the proper size is your only logical choice.

Re: Tool Topic: Cylinder Hone, Ball Hone, 3-Stone, or ???

the right answer is to use the ball hone but i've been using brake mc hones for 10+ years and dozens of cylinders and they come out great. You gotta be careful about the port edges, i do it with my drill press on low speed setting.

you used to be able to buy a really nice one from the auto parts stores but i haven't seen them for sale in a grip so i'm just hoardng the 3-4 i have

Re: Tool Topic: Cylinder Hone, Ball Hone, 3-Stone, or ???

I’m gonna buy a couple ball hones. 1-1/2” & 2”, because that’s the size of honable cylinders I have. They’re ~$20 each. Should I get the 240 grit, or 320 grit? I’m leaning toward 240.

I bought mine from team calamari a few years ago

You can get them practically anywhere for cheaper probably

But they made me laugh in an email convo so I bought it there ha

In case you don't know , you want the ball 'stems' to flex a bit as the hone is inserted . So , if you have a 2" cylinder , as much as a 2.5" hone can be used with great results .

What I'm trying to say is , don't expect good results using a 2" hone in a 2" cylinder .

As stated in description:

“Order by actual bore size, tool produced oversized”

Yeah, I’ve used these before in chev v8’s, so I know how they work. But I appreciate the warning. (edited)

I didn't click the link , as I know what a ball hone looks like . ;)

And , you're welcome . An ounce of prevention ... :)
