Tricky this: mounting 4x4 posts, tops same height

I need to mount eight pressure treated fence posts (4x4s) in concrete, in a row, and have the top end of all of them to be equal distant above the ground (even/horizontal to the plane) so that a 2x4 can be nailed across the tops, one end to other, and be level.


Thanks in advance for suggestions, info, comments and advice.

One approach is to install them a bit longer than needed and cut to the exact height. Using strings installed to guide the setting of each post is also helpful.

To cut the tops, use a square and draw a line all the way around. Then a circular saw will go half way through. If you want the top to crown, set your saw at an angle and cut from all four sides.

This link might help w/ some basics about leveling your posts side to side (especially the batter boards if youíre doing this by yourself): How to Set Fence Posts: Home Improvement Projects | eHow.co.uk

That didnít show you how to level the tops. One way is not to worry about exacting precision about the tops so long as they are roughly level. After posts are set in concrete, you can then cut the top off any posts that exceed the height youíre aiming for with a circular saw. To get a level line for the top of the posts, temporarily install a nail at the top of each terminal post (if setting the end posts first) or at a mark on the side if doing all 8 at once. Make sure the string is set-up the same way on each terminal post. An inexpensive post & string level should cost around $10.

When setting posts in concrete, I usually sets posts deeper than the depth of the concrete pour. While the gravel at bottom of hole needs to be somewhat close, remember that you can move the posts around and use a hammer at the top of posts to make some minor height adjustments. Use a piece of scrap lumber with a mark at ground level to get the approximate depth of gravel needed (forming a tee out of two pieces of lumber with vertical piece used as a depth stop & horizontal piece spanning across post hole at ground level may be helpful). Backfilling with some dirt will help to stabilize post, and it helps if someone can hold the post while someone else pours in the concrete.

Once you do a couple, it will get easier & quicker.
