HI Don

>>>Hi Rob ...Is this some of the good stuff ?<<<

Well my name is not Rob! And no that is not the good stuff at all!

>>>However I have to call into question the angles you have the shafts drawn in at. I don't believe they are accurate.<<<

That’s a good one! You mark on my cad drawings with a line about 2 cubits thick and at the wrong angles but you are not sure about MY shaft angles!!! At least I got my laugh for the day thanks. They are not my shaft angles they come from Gantenbrink’s data so you need to contact him if you disagree! Also extending the KC south shaft will NOT meet the corner of base and apex extensions.

If you are referring to the KC north shaft (the angle B = 32.4712° I have) it is not the actual shaft angle I use the starting point at the end of the horizontal section and the exit point where it would contact casing. The bending that goes on between start and exit points is not that important.
