When laminating multiple pieces of wood together to make a wide slab, you could use a biscuit joiner to align the pieces, but you'd earn the contempt of Samurai Carpenter. In this video, Jesse shows you how HE does it: tap, tap, tap.
Step by step glue-up process:
Apply the glue to the edges of the boards.
Line up the pieces and apply light clamping pressure.
The individual pieces up or down to make them all flush along one edge
Crank down the clamp at one end (the end you just flushed up)
Repeat at the other end: flush the first two boards, flush the next, etc.
If you need to adjust the tension if the clamp in the process, do so.
Clamp down the second end.
Now, add opposing bat clamps to apply force in the opposite direction; this will keep your workpiece flat.
Use a straight edge to double-check the flatness and adjust the. Lamps as needed.
This works for long glue-ups, short glue-ups, and all kinds of glue-ups.
Extra glue-up tip:
If the boards still buckle a little bit—like if one of them has a wane in the end—then you can slide little shims between the bar and the board to push it all into position.
