A properly glued joint may be as strong or stronger than a single piece of wood. however, glue is notably less effective on end-grain surfaces. animal glue is soluble in water, producing joints that can be disassembled using steam to soften the glue.. A finger joint or box joint is one of the popular woodworking joints. you use it to join two pieces of wood at right angles to each other. it is much like a dovetail joint except that the pins are square and not angled.. Most joints are held together with some sort of outside force, such as glue, nails, staples, or screws. anywhere that two pieces of wood need to touch one another to create stability can be considered a type of wood joint. eight types of wood joints..
A weak joint will split in the glueline, either because the glue was too thick or the glue didn’t penetrate the wood correctly. the percentage of wood failure will be very low or nonexistent. a good joint will split mostly in the wood adjacent to the glueline.. Moisture and heat softens glue joints. some woodworkers drill a small hole in the joint and inject steam through a small tube. this works for older antiques that were assembled with organic hide glue, which was widely used in the past.. This joint has ample strength in one direction, but very limited strength in another, as the joint can be easily separated if no glue or other methods are used to secure the joint. with that knowledge, there are some very specific instances where a sliding dovetail is a perfect choice..
