Great video as always Tinman. I have been using those hones for 35 years. Always does a good job. Only difference is I use soapy water for lubricant. I actually submerge the cylinder in a bucket of soapy water when I hone. Works well for me and no messy oil everywhere 👍🏼

Those cylinder hones are excellent! As a truck mechanic I've overhauled many engines throughout the years and I would never put one back together without honing the cylinders with one of these tools. I have never honed a chrome cylinder so I cannot speak of that. Awesome job you are doing with the content!

[@gerrytrader4756]

I hone closed transfer port cylinders with three stone or tri hones and open transfer port cylinders with dingleberry hones or 220 sand paper if they are not to bad. The tri hone will tell you if the cylinder is round, if you have any taper near the top or something else wrong. They will also remove transfer. I use W-D 40 for lube. Great video keep the good stuff coming

[@danielford5455]

Tinman thanks for making this video- I’ve always honed after porting and have used that same brand hone for years- never once have I had issues with the plating - if plating comes off than there’s a bigger issue than the ball home running through it- and you hit the nail on the head when you mention how running the hone through cleans up the chamfers and makes the edges flow better- your best line for sure was “ if you don’t want to hone than don’t hone” it’s crazy how one guy will say not to and it’s like guys who have never tried it get all nervous like your running a jackhammer up and down the hole…. Great video man!

Tinman, honing definitely works. I have used the ball hones I'm many different cylinders on jet ski and marine engines. I was told by a very experienced race engine builder to never use a shoe hone in a two stroke cylinder. He said they can catch on the ports, breaking the shoe and absolutely trash a cylinder. If I rebuild an engine it gets honed unless I don't have that size or am replacing the cylinder. Keep up the great work Tinman. Your knowledge and humbleness is awesome. 🤘🪓🌳

Fantastic and spot on Tinman!!! You totally hit the ball out of the park when you say hello you aren’t honestly honing anything but you a just doing a little bit of a deglaze job to make your rings a good bore to bite and cut and seat and seal up your bore nicely!!! I absolutely do new and used or basically every single engine I build! I’m a warm water underneath my sink for the water lubrication and materials removal so it’s not really even possible to damage the bore with the water process! Yeah man it’s just like 6 rpm’s and a couple seconds of action for a nice surface break not a 9K boring project! LMFFAO

[@davidwagner2280]

I use both, ball hones and three shoe hones. With the the three shoe hone you have to be a little more careful because they can take material off faster then a ball hone. But I like them better because you are working with flat plains, so if you have waffling or low spots they'll show up. Where the ball hone will cover them up.

[@Carboneye7]

Covering them up is better for my ocd

[@michaelgilmore9288]

Hi Tinman. Thank you for ALL that you do to help all of us grunts work on our saws! We are all indebted to you. I was just out on the web looking for a source for the 320 grit silicon carbide flex hone for my Stihl 026 and I found a tool seller that has included an image of the Abrasive Selection page from the Brush Research catalog. It says "For deglazing Nikisil cylinders, we suggest 240 AO." So softer and courser stones than what you are using. And justgjt made the same comment about the aluminum oxide last month. Since we are only wanting to deglaze and/or crosshatch the surface the softer stone makes sense. Removing the aluminum transfer and restoring the cylinder surface rather than jumping right into a new cylinder isn't controversial to me!😁

[@woodcutter4481]

Glad you covered this subject. I started playing with saws a few years ago and purchaced the same brushes you have. I've had great success cleaning up cylinders and also some failures on cylinders that were very worn. As you pointed out speed and duration are all part of the learning process. Wouldn't try chrome myself either. To thin, hard and brittle IMO. Thank's for the video!

[@ooCHICOoo]

[@Hendogg28]

I use the 3 stone spring loaded hones for just about every Atv I rebuild. Never had a problem with one not seating the rings.. Even on chrome/Nikisil cylinders. I once took a Nikisil cylinder for a Suzuki that needed replated and i couldn’t afford to get done so I took my 3 rock hone and honed it out to the next size piston, was a steel sleeve that was plated knocked the plating off of it and then it it back together with a new 1st oversized piston and rings. Rode that thing ram better than when I got it for over a yr sold it to a buddy and he rode the snot out of it for at least two more years before blowing it up..

[@YardpigTSI]

Great channel. I do a lot of Polaris cylinders with Nikasil coating. I ball hone but only go one direction and I hone fast to get the recommended degree. I hone till I see a matt finish. I have also used stones to true the cylinder, but found the ball hones to be easier and less likely to chip or catch. If a cylinder is to the point it needs stones to true it up, it needs to be thrown out, or bored and Nikasil reapplied.

[@jjock3239]

I found this video quite interesting, because prior to watching this, I would never have honed a saw cylinder. I heard your comment about dry honing, and with three stone hones, what I learned long ago, was that dry honing takes off less metal than wet honing. The oil helps clear the debris from the stones, so they continue cutting much longer. My guess, is that the same thing would apply to the ball hones.

[@MrJeepfreak1972]

Well, I posted a link to the manufacturer of those ball hones explaining you can use them on undamaged nikasil plated cylinders but it appears to have been deleted already. Keep up the good work Tinman.

HAHA BBR ! As a fabricator/sign maker, mechanic, 30 year + I know this. I prefer the 3 stone hone due to its being spring loaded and don't have to buy a different hone for different sized cylinders.

*Mineral oil for break in. Semi synthetic at worst. NOT full synthetic. Also, try be mindful about the 'in/out' movement speed you are going to use to achieve the optimal cross hatch angle. This guy makes it look easier than it is, if you have never attempted it before. Make sure you set up your work area so you are in the absolute best position possible to control the drill movements to keep everything nice and square & consistent. That way, being the first ever attempt, it will either go perfectly as planed, or at least allow you to smoothly and accurately respond to anything that is unexpected.

Honing was part of my job and I wouldn't think twice about using a flexihone on those cylinders, I used to hone various jobs to size and instead of changing to finer stones to get the required finish I used to wrap abrasive paper or scotchbrite around the stones.

[@JohnnyDeScoville]

[@johnpower8356]

I own Boston industrial honing Co. I have all types of hones, we do engines and industrial honing on all materials. I usually use sunnen hones, but I love those ball hones for ported 2 strokes, not so much for sizing but for breaking the sharp port corners and somewhat of a cross hatch. You can size with them but to remove stock for sizing you really need like a sunnen positive feed hone. Ball hones can dothe trick tho.

[@boomupengineering]

During my brief stint at Arctic Cat, we would ball hone cylinders at rebuild. Just a couple in-and-outs...that's all. Have to do something to get the rings to seat. I did a lot of jetting and EFI testing and so I got to seize up a number of engines on purpose. Well, I'd lean out jetting and monitor detonation. If careful I'd catch it just before locking up the motor. I think a lot of times we'd just douse the ball hone in WD40 when honing.

[@travisweldmaster7815]

Love that 044, all ofem for that matter, good info buddy thanks

[@patthesoundguy]

If you are going through all the trouble to port a cylinder a good de-glaze is a very important step. A very glazed cylinder is not going to run any where near as good as a good cross hatching. You will notice the difference, especially if you want to run the engine for long periods of time. A glazed cylinder will be weird when it gets hot because the oil has nowhere to live. I have even been known to crosshatch a piston now and then with some 220 or 320 grit wet dry sandpaper 😉 anything to get the oil a place to be.

[@dreamdiction]

I think he should move in and out faster so that the cross hatch angle is increased.

I’ve used the shoe hone and flex hone together on non-nikasil 2-stroke cylinders. I first coat the cylinder with a light coating of oil and run the shoe hone briefly at fairly slow speed. Pop in the flex hone and run just long enough to give a good cross hatch. No expert by any means but has worked well for me on quite the few old Rotax’s.

[@thomasgronek6469]

Thanks TinMan, I did hone, and it looked about like your cylinder. However, after a few heat cycles, I took it apart and looked at what was going on. The cylinder was polished, but there was a MASSIVE amount of cast iron dust. I was using new Cabor rings. In short, after a few short runs, the honing marks were gone, and the bore was polished. I think I'll go back to green scrubbies wrapped around a dowel stick It was a three stone hone

[@bondvagabond42]

If you picture in your mind the old timey tripod style hones, the edge where it touches the cylinder is 90°, so if it catches on something, it catches good. With the flex hone style, the little balls touch at a much more gentle angle, and the force required to flex one up and over a port lip, for example, is much less, so they pop over obstructions without catching and pealing the plating off, cause the plating is weakest at port edges or at the edges of scoring.

[@thelongranger55]

I made my own tool for the job . deep socket wrapped with 3k grit wetdry sand paper & then buttered up with the 3k/350grit diamond paste . I have a video on my channel of the stihl cylinder I’m taking about specifically. I used 100% muriatic acid before I did anything too . A tip for the acid is to stuff the cylinder with toilet paper then soak it with acid but not dripping all over the place . The idea is to make sure the acid stays in the cylinder by sticking to the nikasil coated walls ONLY via soaked acid toilet paper
