EWK 2" to 7" 3 Stones Engine Cylinder Hone Tool Adjustable Cylinder Deglazer Piston Honer 220 Grit

Worked great A+

There's something satisfying about bringing an old engine back to life, although getting everything ready for new rings can involve more work than expected. This adjustable hone is a handy option for the cylinder preparation part of the job. The three-stone design expands to accommodate different bore sizes, and the 220 grit stones are useful for deglazing suitable iron or steel cylinder walls. The quarter-inch drive makes it convenient to use with a compatible drill. The trick is maintaining steady motion, proper lubrication, and the correct crosshatch rather than spending forever in one spot. Check cylinder material and measurements first. Great tool for the home engine rebuilding toolbox.

It will do the job for sure! I’ve used this to hone my CB750Ks cylinders! Unfortunately it has disassembled itself twice in the process. It will totally do the job! But after putting the hone back together twice I wouldn’t count on its durability

Bought the mid-size hone to do rings on a 50cc quad. The hone worked great and I was really impressed with the build quality of the hone and the stones. So impressed in fact I just ordered the large size hone even though I don’t need it at the moment.

Cheap but works just fine! I used this to hone the cylinders on an old Sanborn 165 Compressor pump and it worked just as it should. No complaints. It's easy to adjust the tightness/looseness and the size was perfect for my application! It left a nice crosshatch pattern after I was done! All in all a great little hone!

It works but I'm disappointed with hardness the grinding stones. You also have to very careful because the stones are so soft if you pull it out beyond what you're honing it will cause uneven wear. As far as I can tell when the stones wear out the whole tool becomes trash? It got the job done but I'm not so happy with the way the stone wore down fast & uneven (although the uneven part is my fault) So be very careful not to pull out beyond what you are honing or it will damage the tool.

Was just the right size for the small engine repair i was doing,fast shipping and a lot cheaper price than my local Napa.I would buy again.

Perfect for application.

My first time honing a bore but does the job,the flexy means it's a bit forgiving if you get the angle slightly off when using a drill and can feel when it's right,done 3 of 6 cylinders so far and when taking my non existent experience before looks ok finish,pictures before and after

bon produit je recommande pour le prix

I needed this tool to hone a 500cc cylinder bore after fitting new rings. I bit tricky to close/grip the heads whilst inserting them into the 79mm bore butonce in it did the job perfectly in a matter of seconds. Well worth the money.

So good glad I got the 7" one worked well

I used this for a 500cc Briggs & Stratton 1 cyl OHV engine, 90.5mm bore to deglaze and prep for new rings. Its been 40 years since I used a cylinder hone, and this was a much smaller engine. The hone arrived in the original packaging, undamaged and free of defects. I followed the link to the website and watched the video. I then proceeded to start honing my 1 cylinder and just as quickly stopped after a couple of short tries and being alarmed by the lack of proper crosshatch and the very aggressive surface finish. Time to rethink before the point of no return, I am obviously doing this wrong. I expect some of the problem might be the metallurgy of the B&S cylinder sleeves, maybe they are not as hard as some good cast iron 1970s American V8s that I messed with as a teenager. Maybe the big Makita 1/2" drill with 2 speed gearbox is too fast and too heavy for such a small job. inertia is not your friend here. Maybe the stones on the hone are too new, the edges are quite sharp and crisp. Maybe the tension spring is too heavy even at it's minimum setting. So clean everything, sleep on it and try again the next day. Tried some different drills, settled on a cordless Ryobi One+ drill/driver with the speed range on 1 even with the trigger fully depressed it is nice and slow. And light weight so you aren't fighting to change direction at the end of each stroke. Speaking of which, on a little cylinder like this you're only stroking 2" if you don't want the stones popping out of the bore. Decided to break the stones in a bit. Got a glass 1qt pickle jar and half-filled with water and some dawn dish soap. Held it in the kitchen sink and proceeded to hone it out, working on speed and technique while also cleaning the stones and relieving the crisp corners a bit. It's not what the hone does to the glass, its what the glass does to the stones. Now I have them clean and not digging in. Removed the flex shaft and tried to find a lighter coil spring. Not much luck, the only one i had was too light and didn't give enough tension. But realized that the flex shaft screws on the adjustment bolt quite a distance, so if you don't screw it all the way down you can loosen the tension nut a few turns further up and get less force on the stones in a small bore. Make sure you run it up tight, double nut style, so it doesn't come apart unexpectedly. back to my little engine. Slop on some 10W30 and away we go. Much better this time, I could see a proper cross hatch working into the cylinder wall. However the deeper finish from the first attempt was still evident and I decided not to keep going to try for perfection. The goal was to deglaze, not hone it out .005 because then the new standard rings won't fit. Run my fingernail over it and can feel enough profile that it should seat the new rings. I'm sure this tool will last for many small engine rebuilds, the only noticeable wear was from my "break-in" in the pickle jar. Now we wait for the rebuild kit to arrive. I'll update once it is running and let you know if the smoking and oil consumption goes away.
