From time to time I have found furniture designs that include dowels being passed through a tenon. I have also found plenty of information out there that states a well fitting, glued tenon will fail in the wood long before the glue would give way. Being a newbie I thought I would send the question out to you folks…does putting a dowel through a tenon serve a functional purpose??

It used to be that people pegged tenons in case of glue failure but with modern glues it really isn’t necessary and doesn’t add anything to the strength of the joint (in fact I think in the FWW test it failed sooner than the non pegged version) The pegs do have some advantages though; they look good, save you from having to clamp the joint while the glue sets, and they draw the joint together nice and tightly.

Pegged and drawbore tenons are also useful for places where you want a tight stable joint and want to be able to break down the piece later. I’ve also seen reference to them being used for items that must be assembled onsite because you don’t need to clamp the pieces.
