What is a common result of using insufficient gluing pressure when making a wood joint?

Using insufficient gluing pressure when making a wood joint typically results in thick glue lines, which are indicative of a weak joint. This occurs because the inadequate pressure does not allow the adhesive to spread evenly and adequately saturate the wood fibers, resulting in an incomplete bond. When the glue is applied, it should be squeezed into the joint under pressure so that it can penetrate the wood surfaces effectively. If the pressure is too low, the glue may not fully adhere to the surfaces, leading to excess glue in the joint that remains uncompressed, and ultimately forming a thick line instead of a tight bond.

Thick glue lines can compromise the overall strength of the joint, making it more prone to failure under stress. In a well-executed glue joint, the glue line should be thin and uniform, ensuring a strong connection between the pieces of wood.
