But in terms of case blowout, since the extractor cut is given as 53º, you really can't go too far wrong using that, if you don't like the trig answer.

Rick,
I know what the drawing says, I just wondered what angle you actually used!

GT and I argue over the best ramp angle, he likes a steeper angle, I like a flatter angle. But not more than about 5 degrees different.

Just wondering what you actually set up to cut.
