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?



No telling, but you best answer will come from here.

Just as a follow up, this type of repair can be problematic. I have
done similar. If you did not create totally new, clean, fresh wood
surfaces the glue often fails. Typically you have to drill the hole out
to the next larger size, flush cut the dowels, and drill the next size
up and put in larger dowels. There is just something about fresh glue
not adhering well to old dried glue. My finding is that sanding the old
hole and dowel is not enough.
