Hi. I'm Eric, with Today, I'm going to show you how to hone a cylinder, using a flex-hone.

We're going to need a drill, a flex-hone, cleaning brush, and flex-hone oil. Rocky Mountain carries flex-hones specific for your machine.

The flex-hone tool is perfect for deburring and deglazing cylinder walls. Refer to your owner's manual for recommended honing instructions and intervals. You can use them on both steel and nikasil plated cylinders. On the nikasil, you need to make sure and be really careful. The goal is to simply remove the glaze and the carbon, without damaging the plating.

To do this, make sure you use plenty of flex-hone oil and minimal time honing the cylinder. To start with, we're going to apply the flex-hone oil to the flex-hone. You want to make sure we get plenty on the hone, as well as the cylinder. The flex-hone needs to be rotating when you put it in the cylinder to start with. It's a slow spin, you only want between 500 and 1200 RPMs. Don't use air tools. You want to stroke it quickly. The goal is a 45 degree crosshatch. You only want to do it long enough so that you're deburring the cylinder. Between 5 and 20 seconds is usually enough.

Now that we're done honing, we need to clean out the cylinder, using hot water and soap. We're also using the flex-hone brush. This brush looks big, but it will actually work on many different size cylinders. Once we get it all cleaned out, rinsed off, we're going to dry it. Then we'll apply a light coat of oil to prevent oxidation.

This is what your cylinder should look like. It has a nice 45 degree angle crosshatch to it. The crosshatch allows your new rings to seat better. It also helps with oil lubrication.
