I wouldn't use that tool. Hard to explain, but basically you'll have too much tool flex and your surface won't be flat. Where the tool wipes over the combustion chambers wont be consistant with the area inbetween them.
You really need a facemill, it's actually a fairly precision operation. You also need to set and or veryify insert depth using a comparator or indicator to insure a flat surface with a consistant finish. |
