A dowel that’s broken near the surface is tough to grip with pliers. So drive a small screw into the dowel, then pull it with a claw hammer. 5) Clean up the holes. After removing the dowel, take a twist drill the same diameter as the hole and turn it by hand to clean out any remaining glue or chips.
For a super-strong joint that doesn’t require a lot of precise fitting, try using epoxy and all-thread rod as a substitute for dowels and woodworker’s glue. Drill your holes in the same location as you would for a dowel assembly, but make the holes about 1⁄ 16 ” larger than the diameter of your all-thread rod.

Water or white vinegar will do the job on familiar white carpenter’s glue , and vinegar will dissolve animal-based hide glue that you’re likely to find on older furniture. Use acetone or denatured alcohol if you suspect the joint was glued with epoxy or urethane.
