Thanks, I saw that,maybe someone can check my work:
What I did was take 1/2 of "C" (11.5 degrees) and 1/2 of "D" (26 1/2 degrees) add them together(38 degrees) then subtract them from 180 degrees for a total valve opening of 142 degrees.
Did I go about this the right way? The only reason I ask is that I put this info into the online calculator for custom extractors to find out length and diameter, and I get a Primary tube length of 27.5, which seems okay, but a tube diameter of .01, which is a cocktail straw. Any ideas?
