The housing joint also known as a dado joint is quite simple to make but requires the use of woodwork machinery for accuracy and tight fit. Hand Woodwork tools can be used but for quality appearance and tight fit we recommend ma chine tools.
A housing joint is made by cutting a channel across the face of a piece of wood about three quarters of its depth. You then need to apply some adhesive in the channel before you insert the end of the other piece of wood. This type of joint usually used on the back of drawers because it is strong and withstands the stress from many directions.
