This cylinder hone from KD Tools lets you hone and remove glaze from your engine’s cylinder walls. It works on cylinders from 2″ to 7″ in diameter. You can adjust the tension to control how fast the medium 240-grit stones cut, and you can dial in the diameter with the spread limiter. Prices for the hone start from $20.
I’ll be the first to admit that rebuilding engines is not in my area of expertise, so does anyone have any experience with cylinder honers like this? I’m assuming you can’t just chuck this into your cordless drill, but would need some sort of stable platform such as a drill press or other boring machine. If you’ve worked with a tool like this, let us know in comments.
