Hi George,
Several folks have responded to your question concerning
angles, for what it is worth I also got 5.729 degrees.
There are a couple of formulas you can use. One
common approach is to use
ArcSin, but unless you have a convenient
ArcSin function available that can be problematic.
So instead I like to use this one for y/r (y being
the vertical length of your angle and r the horizontal
length) Degrees = y/r * 180/pi = 3/30*180/3.1456
= 5.729 deg. This way you don't need a
table/function of ArcSin.

Ed,
I measured the taper of the flywheel taper with a
ruler, the draft is 3mm in 30mm. I checked that with a dial indicator and it
was correct - how does one derive the angle of that?
Is it 6 degrees?
