: what's the advantage to haunched tenons, other than filling the groove in
: the end of stiles in frame/panel joinery? I see a lot of designs, and it
: almost seems like the haunch was thrown in arbitrarily.
Haunched tenons ('thrown in' for centuries) are used at the corners of
The haunch is the wood between the end of the mortise and the end of the
If there was no haunch, the end of the stile (of a through jointed frame)
would consist of a slot, the joint becoming in effect a bridle joint.
Such joints will have greater gluing area, but are more difficult to cramp
up at gluing-up time. To keep the shoulders close, cramps are needed along
both the stiles and rails and a 'g' cramp (or similar) is needed to prevent
the flanks of the slot from spreading.
Hence, like other features in joints, ease of assembly is a fundamental
