    I did it in the bottom of the crankcase casing, with both half’s bolted together, and ground down a half round bit for the cutting. The o-ring is far superior. Any machinist can do this for you, but as he will tell you; most of the time is taken in set up time and jig. Making the slot for the o-ring takes the least time.
