It's actually quite simple ... you just make sure all three legs are at 
the same angle.  That assumes, of course, that the tower is straight, 
which I accomplished with a taut string as described in an earlier 
post.  There's nothing unique about a tapered tower ... the legs still 
need to be straight and each leg needs to have the same angle.  That's 
all there is to it.

I trued my tower by building "feet" for the base out of concrete block 
and angle iron, and clamping the base to the angle iron with C-clamps.  
I adjusted each leg one at a time until the angles were all the same 
(89.1 degrees in my case), and then drilled holes and put bolts in them 
to replace the C-clamps that I didn't trust to survive the concrete pour.
