Hi all, brake hones and alloy, its a bloody slow process, I could bore one out in the lathe at work far quicker. If you wanted to remove 1.00mm in total ID, that 2 cuts in the lathe, less than 5 minutes cutting and about 3 minutes to set up. I'd really hate to say how much time it would take to hone out 1.00mm, hours to be honest. A hones real job is to take the highs from the surface finish and form a x hatch pattern for the seals to bed in on. The same goes for engine cyclinder bores. Cutters are required for metal removal.......regards wayne davidson Invers NZ.........
