With a square mark 3 lines on 3 sides of the post at the desired location.
with a circle saw cut through the first line full depth. Use the saw kerf
to guide the blade for the cut on the next side. Doing the same on the
third side, complete the cut.


Use a speed square to fence, tilt the saw base to bevel and cut round and
round. If a straight cut, still use the fence. If nothing else, it lets
you know where your off hand is.
