Cutting 4 x 4's Once in the Ground

I have 4 x 4 fence posts that are already in the ground, but the tops need to be shortened before the post caps go on.

What is the easiest way to cut these squarely and accurately? Obviously my circular saw won't get through it with one pass. Thanks!

Two passes with a circular saw will do it. Just use a straight edge to get an even cut. Alternatives - use a hand saw or a chain saw.

To get them dead square and accurate make a jig out of wood. Jig will have 4 sides and fit over the 4 X 4. The inside dimension should be 1/16" bigger then the 4 X 4 in both directions. 2 opposite sides of the jig should be long enough so that you can put a clamp on to hold it to the 4 X 4. Rest you circular saw on the jig and cut the 4 X 4. If there is more than 1 4 X 4 and you want them at the same final height use a water level to mark and set your cut line and jig.

I do something similar to Jimmiem, but I like to bevel the tops of 4x4 posts. So I would start with a level cut to set the post height, but then lower the jig about 1" and cut all 4 sides at a 45.

So I did it. The jig wouldn't work work as I only had a few inches to cut off and the fence was in the way. I cut it with a stiff sawzall blade and they came out level enough to put the post cap on squarely.

I did have to work more patiently with this approach.....I heard if you're not PATIENT then you'll become ONE.
