I use a laser cutter to create intricate shapes out of 1/4 inch thick re-sawn pine, then laminate them together to form 1/2 and 3/4 inch thick structural elements in small boxes, corbels and briefcases. Sometimes my intricate designs defy easy clamping during the laminating step, sliding laterally out of alignment and leaving ledges which must be sanded away.
When the goal is 3 layers for a thickness of 3/4 inch or more, I've been successful using a corded nailer to pin the layers in place while the glue is still wet. That technique doesn't work for 2 layer thick constructions because the smallest pins which that nailer can handle are longer than the construction's 1/2 inch thickness.
What techniques are available to laminate small wooden objects together which provide precise lateral placement of each object in relation to each other, yet results in a strong, permanent bond?
