I am making a top for a small child's table. It is 30" square and I jointed 3 10" wide pine boards to make it.
While I had it in a vise and was planing the end grain to clean up the marks left by the saw, the vise "let go" and it fell to my garage floor. The middle board suffered a small crack as a result. (The picture is a bit awkward and the angle isn't the best, but the split is on the end. The board is leaning against another one)
You can see a .25" chisel next to it for size comparison. I tried getting glue [edit: Titebond II] in the crack and using clamps to pull it together, but it is so small I wasn't able to get it in. What is the best way to repair this?
