It is a difficult joint to make manually, requiring skilled workmanship. There are different types of dovetail joints. The joint is strong especially when used with glue. The angle of slope varies according to the wood used, purpose of joint and type of work. Typically the slope is 1:6 for softwoods and a shallower 1:8 slope for hardwoods.
