I am currently making a dining table. The joints are mitered, motice and tenon on the apron/legs. This past weekend while preparing the table for finishing I noticed one of the tenons was loose and coming out of the mortice. The reason was due to all the stress I put on the joint as I have to move the table back and forth everytime I want to get around it (I am in a tight space). This is no excuse for a failed joint but I realize that even with all the care I take moving the table I am placing the joints under duress and this has caused the failure.
That said my fix was to drill a couple 1/4" holes in key areas in the top of leg, fill with glue and put a 1/4" dowell in it, spreading the glue inside the joint. This seems to have worked well as the joint is strong this morning when I took the clamps off.
My question is what would your fix have been? And do you recommend I do the same to the other three legs just in case?
