head milling

To use the chart divide the amount to be milled by the number in the chart. Or if you have a particular amount of ccs you want to reduce multiply the amount you want to remove by the number in the chart for example say you have 70cc and you want 65 do 5x.0048=.024 that's how much you need to remove. Or close to it. I'm sure there is a better way out there but that's how is did mine. I wanted to remove 6ccs which was .288 so I just did .030 and it came out to around 7ccs
