How do you clamp a rabbet joint?
Gluing and Clamping There is no mystery to gluing up butt or rabbet joints. Apply a thin, even coat of glue to the mating surfaces (including the shoulder of the rabbet if used), assemble the pieces, align and apply a bit of clamping pressure to hold them in place while the glue dries.
What is a lock dado?
A Lock Dado joint is an improved version of the old KD joint. It uses a machined dado and tenon to precisely align and securely hold the joint and cam-lock fasteners to clamp it in place. This new joint can be assembled and disassembled with just a screw driver, yet the joints are rigid, solid and strong.
How do you clamp wood without bowing?
Use a pair of boards with the work piece between them. When it sets up, it should not be bowed at all. In that case, it’s a good idea to put an “insulating layer” (a sheet of paper or some felt or any such thing) between the hardwood boards and the work pieces.
What is a Knapp joint?

Do dowels prevent cupping?
On small boards, using dowels is an acceptable method of attaching breadboard ends. Once glued and driven home, they’ll keep the main board from cupping.
When did they stop using Knapp joints?
1900
What makes the Knapp joint so special is that it was only used for about 30 years, from 1870 until 1900. This joint is the first known mechanization for making drawers in the industrial revolution age until eventually being replaced by a machine that cuts dovetails.
What is the best joint for a drawer?
Dovetails are the strongest joint used in drawers. Like the box joint, a dovetail joint consists of fingers that fit together to increase surface area. Dovetails have a complex shape with angled surfaces that lock the two sides of a joint together. Once glued, a dovetail joint only can fail by breaking the wood.
