I took the sprocket cover off a while ago and have been trying to decide what to do with it as far as cool vents. After a light bulb type idea went off in my head I came up with this...
First I found the relative center line with a pair of dial calipers and marked it. Then I used a compass to draw the lines moving outward. I measured with the calipers and marked equally spaced lines to set the compass.

I set it up in the Bridgeport and away we go!
After all the holes were drilled
Then it was off to the buffing wheel!
The polishing didn't come out as well as it could but I used red ScotchBrite, then 600 grit, then 1000, then the buffing wheel.
