About 6 months ago I replaced a dowel in a table leg. The wood is dark and fine-grained and looks like cherry. The leg is fastened to the upright with two dowels about 5/8 " diameter. I glued both dowels with titebond 2.
Yesterday the leg and post came back. It had come off again. The glue on the new dowel was still soft and colored blue. Any ideas why yellow glue would not set up, and why it turned blue? Would residue of hide glue do this?
