How to repair chair pocket joints with limited tools
Spread the joint apart and scrape off any excess,loose glue. Spread your wood glue over all the surfaces of the joint, in any dowel rod holes and around dowels. Make sure there's a groove in the dowel rod so excess glue can escape. Press the joint together firmly, tapping it with the hammer. Take your rope and wrap it around the seat frame of the chair and tie a knot leaving enough slack so you can loop the hammer or other object in the rope and twist it to tighten the rope around the frame, clamping the joint tight,like tightening a tourniquet. Let the glue dry 24 hours and you should be good to go.
