These joints are inherently tricky.
Metals, being stronger and harder than wood, must be joined to softer materials
by providing large surfaces of contact for the transmission of stresses.
If adhesive is used to fasten metals to voood, the surface of the metals must be very clean from grease and coarse sanded to make it rough. Such joints should only be made to work In shear. Peeling forces will break them easily. Whenever possible steel fasteners should be used as shown above.
