What You'll Need
Power drill
Safety glasses
Hand gloves
Soapy water
Lint-free cloth
Motor oil

Cylinder honing is a moderately easy project often taken to be a complicated one requiring professional assistance. It is primarily a process of polishing metal which can be easily handled at home with inexpensive, widely available tools once your engine has been disassembled and the cylinders have been exposed.


Step 1 - Choose the Tool

Choosing the appropriate tool is mandatory to attain the desired results and therefore, choose the suitable honing tool in regards to the size of your cylinder. If the cylinder that you wish to hone is about 2 inches in width, purchase a tool which is not bigger than this width. Once applied, the tool will involuntarily increase in size which provides sufficient pressure to the cylinder’s walls during the process of polishing. It is worthy to note and remember while you choose the tool that the quality or quantity of the polishing does not depend upon the dimensions of the tool but rather on the amount of time it is kept or used within the cylinder.

Step 2 - Set the Speed of your Power Drill

Various devices or tools can be used for this step but a power drill is highly recommended considering its convenience. The accurate rotating speed of your power drill should be 1200 to 1600 rpm and see to it that this requirement can be well fulfilled by your power drill when operated at full throttle. You must set the speed switch on your drill (if it has one) to about 1400 rpm for this activity.

Step 3 - Apply Lubricant

Move forward by applying a mineral oil lubricant, a specific lubricant for cylinder honing or an oil-based lubricant free heartedly to the device you shall be using for honing and see to it that the tool is well lubricated. Use your drill to spin the honing device around gently/slowly and pour out oil over the complete surface area it will come in contact with. See to it that you apply enough oil to achieve a fairly well-diluted surface.

Step 4 - Use the Power Drill

Use safety glasses and hand gloves for safety purposes during this step. Hold the trigger of your drill steadily and setting it at the accurate speed, shove it in and out of the disassembled cylinder a couple of times. This method removes metal promptly and so, it is a good idea to inspect the cylinder walls for results after 4 to 5 thrusts. Try to remove as little metal as possible but at the same time, aim at achieving a shiny surface without any apparent scratches or marks. Therefore, when you think your job is half done, reverse the course of your drill in order to attain a crisscross model which allows oil to fuse firmly onto the walls of your cylinder.

Step 5 - Wash and Polish

Lastly, use soapy water with a lint-free cloth to thoroughly wash the surface area and as much metal away as possible which can be followed up by the application of motor oil to the same surface in order to avoid possible oxidation in future.
