The 6x6 center post on our deck came with a slight bend or warp to it. Over the last several year the warp has gotten worse, which in turn has had me worried.
So, in an effort to correct, my neighbor helped install an ~80" steel box-type post against the warped post. Three holes were drilled (top, center and bottom) through both posts and monster bolts were inserted and tightened down.
The plan is to slowly (every couple of days) torque the nuts to pull the warped wooden post into vertical alignment with the steel post.
Initial indication is good with the wooden post responding as we intended.
