SM Head Modifications on a budget
Here's some before and after pictures of the bowl blend. This took about 2 minutes using a 60 grit 1" diameter cartridge roll. In the before pictures, the black ring is the 45 degree seat, the red is the 60 degree bottom cut and the purple lines are the blend zone which includes the 70 degree bottom cut. The 2 blue rings perpendicular to the purple lines are the ridges to be removed. A couple of casting lines down the sides of the bowl were also smoothed out.
