I should have mentioned the relationship between velocity and lifter 
size. You'll notice from the graph that the maximum velocity is 0.006 
in/deg.  Multiply this number by 360/Pi and you will get the radius of 
the lifter needed. 0.688 in this case.  You need add a safety factor for 
chamfer, slop, etc.  A good design should use the entire lifter to get 
the maximum performance.
