I am cutting (3) 4x4 support posts for beams supporting the joists of
a deck. One corner post is at the height I need. The posts are 10'
apart. Can I set a straight 2x10 on edge on the correct corner post
and use a level at the next post to determine the correct height so
that the post is level with the corner post? How accurate is a level
used at the end of a 10' board?
Once the second post is level with the corner post I was going to use
the same technique until all the posts were level? Is there a better
way to make sure the posts are level over 30'?
thanks tom
