Building a Raised Garden box, rebar getting stuck
I am building a raised Garden box using the landscaping timbers. I am using 4 layers of timbers and am dovetailing the corners. My problem is the rebar are not going through the hole into the next timber. I think my problem is the timbers are shifting and the holes are going out of aliment. So what is the right technique to do this? Do two layers at a time? Have someone else hold the timbers so they don't shift? When I did a box with only 2 layers I had no problems hammering the rebar through the timber holes.
